* For backwards compatibility, here is a version of the

* Note that the current version of that structure requires VMX to
* pass down the VA of the mapped file. Before host support was added
* there was nothing of the sort. So, when the driver sees the ioctl
* with a parameter that is the sizeof
* VMCIQueuePairPageFileInfo_NoHostQP then it can infer that the version
* of VMX running can't attach to host end points because it doesn't
* provide the VA of the mapped files.
*
* The Linux driver doesn't get an indication of the size of the
* structure passed down from user space. So, to fix a long standing
* but unfiled bug, the _pad field has been renamed to version.
* Existing versions of VMX always initialize the PageFileInfo
* structure so that _pad, er, version is set to 0.
*
* A version value of 1 indicates that the size of the structure has
* been increased to include two UVA's: produceUVA and consumeUVA.
* These UVA's are of the mmap()'d queue contents backing files.
*
* In addition, if when VMX is sending down the
* VMCIQueuePairPageFileInfo structure it gets an error then it will
* try again with the _NoHostQP version of the file to see if an older
* VMCI kernel module is running.

* Memory Barriers
* ===============
*
* Terminology
* -----------
*
* A compiler memory barrier prevents the compiler from re-ordering memory
* accesses accross the barrier. It is not a CPU instruction, it is a compiler
* directive (i.e. it does not emit any code).
*
* A CPU memory barrier prevents the CPU from re-ordering memory accesses
* accross the barrier. It is a CPU instruction.
*
* A memory barrier is the union of a compiler memory barrier and a CPU memory
* barrier. A compiler memory barrier is a useless construct by itself. It is
* only useful when combined with a CPU memory barrier, to implement a memory
* barrier.
*
* Semantics
* ---------
*
* At the time COMPILER_*_BARRIER were created (and references to them were
* added to the code), the code was only targetting x86. The intent of the code
* was really to use a memory barrier, but because x86 uses a strongly ordered
* memory model, the CPU would not re-order memory accesses, and the code could
* get away with using just a compiler memory barrier. So COMPILER_*_BARRIER
* were born and were implemented as compiler memory barriers _on x86_. But
* make no mistake, _the semantics that the code expects from
* COMPILER_*_BARRIER are that of a memory barrier_!
*
* DO NOT USE!
* -----------
*
* On at least one non-x86 architecture, COMPILER_*_BARRIER are
* 1) Misnomers
* 2) Not fine-grained enough to provide the best performance.
* For the above two reasons, usage of COMPILER_*_BARRIER is now deprecated.
* _Do not add new references to COMPILER_*_BARRIER._ Instead, precisely
* document the intent of your code by using
* <mem_type/purpose>_<before_access_type>_BARRIER_<after_access_type>.
* Existing references to COMPILER_*_BARRIER are being slowly but surely
* converted, and when no references are left, COMPILER_*_BARRIER will be
* retired.
*
* Thanks for pasting this whole comment into every architecture header.

* <*_access type> is either R(load), W(store) or RW(any).
*
* Above every use of these memory barriers in the code, there _must_ be a
* comment to justify the use, i.e. a comment which:
*
* 1) Precisely identifies which memory accesses must not be re-ordered across
* the memory barrier.
* 2) Explains why it is important that the memory accesses not be re-ordered.
*
* Thanks for pasting this whole comment into every architecture header.
*
* On x86, we only need to care specifically about store-load reordering on
* normal memory types. In other cases, only a compiler barrier is needed. The
* ST_LD barrier is implemented with a locked xor operation (instead of the
* mfence instruction) for performance reasons. See PR 1674199 for more
* details.
*
* On x64, special instructions are only provided for load-load (lfence) and

* VMCIQueueHeader
*
* A Queue cannot stand by itself as designed. Each Queue's header
* contains a pointer into itself (the producerTail) and into its peer
* (consumerHead). The reason for the separation is one of
* accessibility: Each end-point can modify two things: where the next
* location to enqueue is within its produceQ (producerTail); and
* where the next dequeue location is in its consumeQ (consumerHead).
*
* An end-point cannot modify the pointers of its peer (guest to
* guest; NOTE that in the host both queue headers are mapped r/w).
* But, each end-point needs read access to both Queue header
* structures in order to determine how much space is used (or left)
* in the Queue. This is because for an end-point to know how full
* its produceQ is, it needs to use the consumerHead that points into
* the produceQ but -that- consumerHead is in the Queue header for
* that end-points consumeQ.
*
* Thoroughly confused? Sorry.
*
* producerTail: the point to enqueue new entrants. When you approach
* a line in a store, for example, you walk up to the tail.
*
* consumerHead: the point in the queue from which the next element is
* dequeued. In other words, who is next in line is he who is at the
* head of the line.
*
* Also, producerTail points to an empty byte in the Queue, whereas
* consumerHead points to a valid byte of data (unless producerTail ==
* consumerHead in which case consumerHead does not point to a valid
* byte of data).
*
* For a queue of buffer 'size' bytes, the tail and head pointers will be in
* the range [0, size-1].
*
* If produceQHeader->producerTail == consumeQHeader->consumerHead
* then the produceQ is empty.

* In the Atomic_* definitions below, memory ordering and atomicity are somewhat
* conflated in an inconsistent manner. First, we have Atomic_{Read,Write},
* which only guarantees single copy atomicity, i.e. that the read/write occurs
* in an atomic fashion, but have no implication on memory ordering. The second
* class of Atomics are all the non-unfenced operations excluding
* Atomic_{Read,Write}*, which both imply atomicity and act as a memory barrier,
* implying sequentially consistent ordering of the atomic operation with all
* loads/stores prior to and after it.
*
* Since on x86, the second class of operations are associated with LOCK
* semantics, assumptions have been made about the ordering these operations
* imply on surrounding code (see for example the vmkernel's RefCount
* implementation). As a result, on arm64 we have to provide these same
* guarantees. We do this by making use of DMB barriers both before and after
* the atomic ldrx/strx sequences. A barrier before and after is required to
* avoid having part of the atomic operation reordered with surrounding code,
* e.g. a store-load reordering of the strx with a following load outside the
* Atomic_ op. For the first class of operations, Atomic_{Read,Write}, we do not
* implement a barrier.
*
* This implementation of Atomic operations is suboptimal on arm64, since
* both atomicity and memory ordering are fused together. Ideally the Atomic
* operations would only imply atomicity, and an explicit memory barrier in the
* surrounding code used to enforce ordering where necessary. This would eschew
* the need for the DMBs. A middle ground can be implemented where we use the
* arm64 load-acquire/store-release exclusive instructions to implement Atomics.
* This would imply sequential consistency of the Atomic operations (but not
* with any of the surrounding non-atomic operations) without the need for a
* DMB. Using these without a DMB today can still result in problematic
* reordering by the processor with surrounding non-atomic operations, e.g. a
* store-load reordering with a stlxr. Future optimization for arm64 should
* consider the wider change required at the call sites to minimize DMBs.

*
* 1) The constraint cannot be "m", because the memory location the compiler
* chooses could then be relative to %ebx.
*
* 2) The constraint cannot be a register class which contains %ebx (such as
* "r" or "q"), because the register the compiler chooses could then be
* %ebx. (This happens when compiling the Fusion UI with gcc 4.2.1, Apple
* build 5577.)
*
* 3) Using register classes even for other values is problematic, as gcc
* can decide e.g. %ecx == %edi == 0 (as compile-time constants) and
* ends up using one register for two things. Which breaks xchg's ability
* to temporarily put the PIC pointer somewhere else. PR772455
*
* For that reason alone, the __asm__ statement should keep the regions
* where it temporarily modifies %ebx as small as possible, and should
* prefer specific register assignments.

* Work queues and delayed work queues.
*
* Prior to 2.5.41, the notion of work queues did not exist. Taskqueues are
* used for work queues and timers are used for delayed work queues.
*
* After 2.6.20, normal work structs ("work_struct") and delayed work
* ("delayed_work") structs were separated so that the work_struct could be
* slimmed down. The interface was also changed such that the address of the
* work_struct itself is passed in as the argument to the work function. This
* requires that one embed the work struct in the larger struct containing the
* information necessary to complete the work and use container_of() to obtain
* the address of the containing structure.
*
* Users of these macros should embed a compat_work or compat_delayed_work in
* a larger structure, then specify the larger structure as the _data argument
* for the initialization functions, specify the work function to take
* a compat_work_arg or compat_delayed_work_arg, then use the appropriate
* _GET_DATA macro to obtain the reference to the structure passed in as _data.
* An example is below.
*
*
* typedef struct WorkData {
* int data;
* compat_work work;
* } WorkData;
*
*
* void
* WorkFunc(compat_work_arg data)

/*
* FIELD can be defined to process the CPUID information provided in the
* following CPUID_FIELD_DATA macro.
*
* The first parameter is the CPUID level of the feature (must be defined in
* CPUID_ALL_LEVELS, above).
*
* The second parameter is the CPUID sub-level (subleaf) of the feature. Please
* make sure here the number is consistent with the "subleaf count" in
* CPUIDLEVEL macro. I.e., if a feature is being added to a _new_ subleaf,
* update the subleaf count above as well.
*
* The third parameter is the result register.
*
* The fourth and fifth parameters are the bit position of the field and the
* width, respectively.
*
* The sixth is the name of the field.
*
* The seventh parameter specifies the monitor support characteristics for
* this field. The value must be a valid CpuidFieldSupported value (omitting
* CPUID_FIELD_SUPPORT_ for convenience). The meaning of those values are
* described below.
*
* The eighth parameter specifies the first virtual hardware version that
* implements the field (if 7th field is YES or ANY), or 0 (if 7th field is
* NO or NA). The field's hardware version must match the version in
* defaultMasks (cpuidcompat.c) if defined there, and must be less than or
* equal to the version of the cpuid leaf it's in.
*
* The eighth parameter describes whether the feature is capable of being used
* by usermode code (TRUE), or just CPL0 kernel code (FALSE).
*
* FLAG is defined identically to FIELD, but its accessors are more appropriate
* for 1-bit flags, and compile-time asserts enforce that the size is 1 bit
* wide.
*/
/*
* CpuidFieldSupported is made up of the following values:
*
* NO: A feature/field that IS NOT SUPPORTED by the monitor. Even
* if the host supports this feature, we will never expose it to
* the guest.
*
* YES: A feature/field that IS SUPPORTED by the monitor. If the
* host supports this feature, we will expose it to the guest. If
* not, then we will not set the feature.
*
* ANY: A feature/field that IS ALWAYS SUPPORTED by the monitor.
* Even if the host does not support the feature, the monitor can
* expose the feature to the guest. As with "YES", the guest cpuid
* value defaults to the host/evc cpuid value. But usually the
* guest cpuid value is recomputed at power on, ignoring the default
* value.
*
*
* NA: Only legal for levels not masked/tested by default (see
* above for this definition). Such fields must always be marked
* as NA.
*
* These distinctions, when combined with the feature's CPL3
* properties can be translated into a common CPUID mask string as
* follows:
*
* NO + CPL3 --> "R" (Reserved). We don't support the feature,
* but we can't properly hide this from applications when using
* direct execution or HV with apps that do try/catch/fail, so we
* must still perform compatibility checks.
*
* NO + !CPL3 --> "0" (Masked). We can hide this from the guest.
*
* YES --> "H" (Host). We support the feature, so show it to the
* guest if the host has the feature.
*
* ANY/NA --> "X" (Ignore). By default, don't perform checks for
* this feature bit. Per-GOS masks may choose to set this bit in
* the guest. (e.g. the APIC feature bit is always set to 1.)
*
* See lib/cpuidcompat/cpuidcompat.c for any possible overrides to
* these defaults.

/* **********************************************************
* GCC's intrinsics for the lssb and mssb family produce sub-optimal code,
* so we use inline assembly to improve matters. However, GCC cannot
* propagate constants through inline assembly, so we help GCC out by
* allowing it to use its intrinsics for compile-time constant values.
* Some day, GCC will make better code and these can collapse to intrinsics.
*
* For example, in Decoder_AddressSize, inlined into VVT_GetVTInstrInfo:
* __builtin_ffs(a) compiles to:
* mov $0xffffffff, %esi
* bsf %eax, %eax
* cmovz %esi, %eax
* sub $0x1, %eax
* and $0x7, %eax
*
* While the code below compiles to:
* bsf %eax, %eax
* sub $0x1, %eax
*
* Ideally, GCC should have recognized non-zero input in the first case.
* Other instances of the intrinsic produce code like
* sub $1, %eax; add $1, %eax; clts

Version 2, June 1991

51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.
