     2     NOTE! This copyright does *not* cover user programs that use kernel
     3   services by normal system calls - this is merely considered normal use
     4   of the kernel, and does *not* fall under the heading of "derived work".
     5   Also note that the GPL below is copyrighted by the Free Software
     6   Foundation, but the instance of code that it refers to (the Linux
     7   kernel) is copyrighted by me and others who actually wrote it.
     8  
     9   Also note that the only valid version of the GPL as far as the kernel
    10   is concerned is _this_ particular version of the license (ie v2, not
    11   v2.2 or v3.x or whatever), unless explicitly otherwise stated.

    19  
    20   Copyright (C) 1989, 1991 Free Software Foundation, Inc.
    21                         51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
    22   Everyone is permitted to copy and distribute verbatim copies
    23   of this license document, but changing it is not allowed.
    24  
    25  			    Preamble
    26  
    27    The licenses for most software are designed to take away your
    28  freedom to share and change it.  By contrast, the GNU General Public
    29  License is intended to guarantee your freedom to share and change free
    30  software--to make sure the software is free for all its users.  This
    31  General Public License applies to most of the Free Software
    32  Foundation's software and to any other program whose authors commit to
    33  using it.  (Some other Free Software Foundation software is covered by
    34  the GNU Library General Public License instead.)  You can apply it to
    35  your programs, too.
    36  
    37    When we speak of free software, we are referring to freedom, not
    38  price.  Our General Public Licenses are designed to make sure that you
    39  have the freedom to distribute copies of free software (and charge for
    40  this service if you wish), that you receive source code or can get it
    41  if you want it, that you can change the software or use pieces of it
    42  in new free programs; and that you know you can do these things.
    43  
    44    To protect your rights, we need to make restrictions that forbid
    45  anyone to deny you these rights or to ask you to surrender the rights.
    46  These restrictions translate to certain responsibilities for you if you
    47  distribute copies of the software, or if you modify it.
    48  
    49    For example, if you distribute copies of such a program, whether
    50  gratis or for a fee, you must give the recipients all the rights that
    51  you have.  You must make sure that they, too, receive or can get the
    52  source code.  And you must show them these terms so they know their
    53  rights.
    54  
    55    We protect your rights with two steps: (1) copyright the software, and
    56  (2) offer you this license which gives you legal permission to copy,
    57  distribute and/or modify the software.
    58  
    59    Also, for each author's protection and ours, we want to make certain
    60  that everyone understands that there is no warranty for this free
    61  software.  If the software is modified by someone else and passed on, we
    62  want its recipients to know that what they have is not the original, so
    63  that any problems introduced by others will not reflect on the original
    64  authors' reputations.
    65  
    66    Finally, any free program is threatened constantly by software
    67  patents.  We wish to avoid the danger that redistributors of a free
    68  program will individually obtain patent licenses, in effect making the
    69  program proprietary.  To prevent this, we have made it clear that any
    70  patent must be licensed for everyone's free use or not licensed at all.
    71  
    72    The precise terms and conditions for copying, distribution and
    73  modification follow.
    74  
    75  		    GNU GENERAL PUBLIC LICENSE
    76     TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
    77  
    78    0. This License applies to any program or other work which contains
    79  a notice placed by the copyright holder saying it may be distributed
    80  under the terms of this General Public License.  The "Program", below,
    81  refers to any such program or work, and a "work based on the Program"
    82  means either the Program or any derivative work under copyright law:
    83  that is to say, a work containing the Program or a portion of it,
    84  either verbatim or with modifications and/or translated into another
    85  language.  (Hereinafter, translation is included without limitation in
    86  the term "modification".)  Each licensee is addressed as "you".
    87  
    88  Activities other than copying, distribution and modification are not
    89  covered by this License; they are outside its scope.  The act of
    90  running the Program is not restricted, and the output from the Program
    91  is covered only if its contents constitute a work based on the
    92  Program (independent of having been made by running the Program).
    93  Whether that is true depends on what the Program does.
    94  
    95    1. You may copy and distribute verbatim copies of the Program's
    96  source code as you receive it, in any medium, provided that you
    97  conspicuously and appropriately publish on each copy an appropriate
    98  copyright notice and disclaimer of warranty; keep intact all the
    99  notices that refer to this License and to the absence of any warranty;
   100  and give any other recipients of the Program a copy of this License
   101  along with the Program.
   102  
   103  You may charge a fee for the physical act of transferring a copy, and
   104  you may at your option offer warranty protection in exchange for a fee.
   105  
   106    2. You may modify your copy or copies of the Program or any portion
   107  of it, thus forming a work based on the Program, and copy and
   108  distribute such modifications or work under the terms of Section 1
   109  above, provided that you also meet all of these conditions:
   110  
   111      a) You must cause the modified files to carry prominent notices
   112      stating that you changed the files and the date of any change.
   113  
   114      b) You must cause any work that you distribute or publish, that in
   115      whole or in part contains or is derived from the Program or any
   116      part thereof, to be licensed as a whole at no charge to all third
   117      parties under the terms of this License.
   118  
   119      c) If the modified program normally reads commands interactively
   120      when run, you must cause it, when started running for such
   121      interactive use in the most ordinary way, to print or display an
   122      announcement including an appropriate copyright notice and a
   123      notice that there is no warranty (or else, saying that you provide
   124      a warranty) and that users may redistribute the program under
   125      these conditions, and telling the user how to view a copy of this
   126      License.  (Exception: if the Program itself is interactive but
   127      does not normally print such an announcement, your work based on
   128      the Program is not required to print an announcement.)
   129  
   130  These requirements apply to the modified work as a whole.  If
   131  identifiable sections of that work are not derived from the Program,
   132  and can be reasonably considered independent and separate works in
   133  themselves, then this License, and its terms, do not apply to those
   134  sections when you distribute them as separate works.  But when you
   135  distribute the same sections as part of a whole which is a work based
   136  on the Program, the distribution of the whole must be on the terms of
   137  this License, whose permissions for other licensees extend to the
   138  entire whole, and thus to each and every part regardless of who wrote it.
   139  
   140  Thus, it is not the intent of this section to claim rights or contest
   141  your rights to work written entirely by you; rather, the intent is to
   142  exercise the right to control the distribution of derivative or
   143  collective works based on the Program.
   144  
   145  In addition, mere aggregation of another work not based on the Program
   146  with the Program (or with a work based on the Program) on a volume of
   147  a storage or distribution medium does not bring the other work under
   148  the scope of this License.
   149  
   150    3. You may copy and distribute the Program (or a work based on it,
   151  under Section 2) in object code or executable form under the terms of
   152  Sections 1 and 2 above provided that you also do one of the following:
   153  
   154      a) Accompany it with the complete corresponding machine-readable
   155      source code, which must be distributed under the terms of Sections
   156      1 and 2 above on a medium customarily used for software interchange; or,
   157  
   158      b) Accompany it with a written offer, valid for at least three
   159      years, to give any third party, for a charge no more than your
   160      cost of physically performing source distribution, a complete
   161      machine-readable copy of the corresponding source code, to be
   162      distributed under the terms of Sections 1 and 2 above on a medium
   163      customarily used for software interchange; or,
   164  
   165      c) Accompany it with the information you received as to the offer
   166      to distribute corresponding source code.  (This alternative is
   167      allowed only for noncommercial distribution and only if you
   168      received the program in object code or executable form with such
   169      an offer, in accord with Subsection b above.)
   170  
   171  The source code for a work means the preferred form of the work for
   172  making modifications to it.  For an executable work, complete source
   173  code means all the source code for all modules it contains, plus any
   174  associated interface definition files, plus the scripts used to
   175  control compilation and installation of the executable.  However, as a
   176  special exception, the source code distributed need not include
   177  anything that is normally distributed (in either source or binary
   178  form) with the major components (compiler, kernel, and so on) of the
   179  operating system on which the executable runs, unless that component
   180  itself accompanies the executable.
   181  
   182  If distribution of executable or object code is made by offering
   183  access to copy from a designated place, then offering equivalent
   184  access to copy the source code from the same place counts as
   185  distribution of the source code, even though third parties are not
   186  compelled to copy the source along with the object code.
   187  
   188    4. You may not copy, modify, sublicense, or distribute the Program
   189  except as expressly provided under this License.  Any attempt
   190  otherwise to copy, modify, sublicense or distribute the Program is
   191  void, and will automatically terminate your rights under this License.
   192  However, parties who have received copies, or rights, from you under
   193  this License will not have their licenses terminated so long as such
   194  parties remain in full compliance.
   195  
   196    5. You are not required to accept this License, since you have not
   197  signed it.  However, nothing else grants you permission to modify or
   198  distribute the Program or its derivative works.  These actions are
   199  prohibited by law if you do not accept this License.  Therefore, by
   200  modifying or distributing the Program (or any work based on the
   201  Program), you indicate your acceptance of this License to do so, and
   202  all its terms and conditions for copying, distributing or modifying
   203  the Program or works based on it.
   204  
   205    6. Each time you redistribute the Program (or any work based on the
   206  Program), the recipient automatically receives a license from the
   207  original licensor to copy, distribute or modify the Program subject to
   208  these terms and conditions.  You may not impose any further
   209  restrictions on the recipients' exercise of the rights granted herein.
   210  You are not responsible for enforcing compliance by third parties to
   211  this License.
   212  
   213    7. If, as a consequence of a court judgment or allegation of patent
   214  infringement or for any other reason (not limited to patent issues),
   215  conditions are imposed on you (whether by court order, agreement or
   216  otherwise) that contradict the conditions of this License, they do not
   217  excuse you from the conditions of this License.  If you cannot
   218  distribute so as to satisfy simultaneously your obligations under this
   219  License and any other pertinent obligations, then as a consequence you
   220  may not distribute the Program at all.  For example, if a patent
   221  license would not permit royalty-free redistribution of the Program by
   222  all those who receive copies directly or indirectly through you, then
   223  the only way you could satisfy both it and this License would be to
   224  refrain entirely from distribution of the Program.
   225  
   226  If any portion of this section is held invalid or unenforceable under
   227  any particular circumstance, the balance of the section is intended to
   228  apply and the section as a whole is intended to apply in other
   229  circumstances.
   230  
   231  It is not the purpose of this section to induce you to infringe any
   232  patents or other property right claims or to contest validity of any
   233  such claims; this section has the sole purpose of protecting the
   234  integrity of the free software distribution system, which is
   235  implemented by public license practices.  Many people have made
   236  generous contributions to the wide range of software distributed
   237  through that system in reliance on consistent application of that
   238  system; it is up to the author/donor to decide if he or she is willing
   239  to distribute software through any other system and a licensee cannot
   240  impose that choice.
   241  
   242  This section is intended to make thoroughly clear what is believed to
   243  be a consequence of the rest of this License.
   244  
   245    8. If the distribution and/or use of the Program is restricted in
   246  certain countries either by patents or by copyrighted interfaces, the
   247  original copyright holder who places the Program under this License
   248  may add an explicit geographical distribution limitation excluding
   249  those countries, so that distribution is permitted only in or among
   250  countries not thus excluded.  In such case, this License incorporates
   251  the limitation as if written in the body of this License.
   252  
   253    9. The Free Software Foundation may publish revised and/or new versions
   254  of the General Public License from time to time.  Such new versions will
   255  be similar in spirit to the present version, but may differ in detail to
   256  address new problems or concerns.
   257  
   258  Each version is given a distinguishing version number.  If the Program
   259  specifies a version number of this License which applies to it and "any
   260  later version", you have the option of following the terms and conditions
   261  either of that version or of any later version published by the Free
   262  Software Foundation.  If the Program does not specify a version number of
   263  this License, you may choose any version ever published by the Free Software
   264  Foundation.
   265  
   266    10. If you wish to incorporate parts of the Program into other free
   267  programs whose distribution conditions are different, write to the author
   268  to ask for permission.  For software which is copyrighted by the Free
   269  Software Foundation, write to the Free Software Foundation; we sometimes
   270  make exceptions for this.  Our decision will be guided by the two goals
   271  of preserving the free status of all derivatives of our free software and
   272  of promoting the sharing and reuse of software generally.
   273  
   274  			    NO WARRANTY
   275  
   276    11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
   277  FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
   278  OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
   279  PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
   280  OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
   281  MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
   282  TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
   283  PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
   284  REPAIR OR CORRECTION.
   285  
   286    12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
   287  WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
   288  REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
   289  INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
   290  OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
   291  TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
   292  YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
   293  PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
   294  POSSIBILITY OF SUCH DAMAGES.
   295  
   296  		     END OF TERMS AND CONDITIONS
   297  
   298  	    How to Apply These Terms to Your New Programs
   299  
   300    If you develop a new program, and you want it to be of the greatest
   301  possible use to the public, the best way to achieve this is to make it
   302  free software which everyone can redistribute and change under these terms.
   303  
   304    To do so, attach the following notices to the program.  It is safest
   305  to attach them to the start of each source file to most effectively
   306  convey the exclusion of warranty; and each file should have at least
   307  the "copyright" line and a pointer to where the full notice is found.
   308  
   309      <one line to give the program's name and a brief idea of what it does.>
   310      Copyright (C) <year>  <name of author>
   311  
   312      This program is free software; you can redistribute it and/or modify
   313      it under the terms of the GNU General Public License as published by
   314      the Free Software Foundation; either version 2 of the License, or
   315      (at your option) any later version.
   316  
   317      This program is distributed in the hope that it will be useful,
   318      but WITHOUT ANY WARRANTY; without even the implied warranty of
   319      MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
   320      GNU General Public License for more details.
   321  
   322      You should have received a copy of the GNU General Public License
   323      along with this program; if not, write to the Free Software
   324      Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
   325  
   326  
   327  Also add information on how to contact you by electronic and paper mail.
   328  
   329  If the program is interactive, make it output a short notice like this
   330  when it starts in an interactive mode:
   331  
   332      Gnomovision version 69, Copyright (C) year name of author
   333      Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
   334      This is free software, and you are welcome to redistribute it
   335      under certain conditions; type `show c' for details.
   336  
   337  The hypothetical commands `show w' and `show c' should show the appropriate
   338  parts of the General Public License.  Of course, the commands you use may
   339  be called something other than `show w' and `show c'; they could even be
   340  mouse-clicks or menu items--whatever suits your program.
   341  
   342  You should also get your employer (if you work as a programmer) or your
   343  school, if any, to sign a "copyright disclaimer" for the program, if
   344  necessary.  Here is a sample; alter the names:
   345  
   346    Yoyodyne, Inc., hereby disclaims all copyright interest in the program
   347    `Gnomovision' (which makes passes at compilers) written by James Hacker.

   351  
   352  This General Public License does not permit incorporating your program into
   353  proprietary programs.  If your program is a subroutine library, you may
   354  consider it more useful to permit linking proprietary applications with the
   355  library.  If this is what you want to do, use the GNU Library General
   356  Public License instead of this License.
