Jose Fonseca 65bd4159b3 rtasm: Generalize executable memory allocator to all Unices.
We're only using fairly portable standard Unix calls here, so might as
well save ourselves future trouble by enabling on all Unices by default.

Emil Velikov 4dd445f1cf gallium/rtasm: handle mmap failures appropriately
For a variety of reasons mmap (selinux and pax to name
a few) and can fail and with current code. This will
result in a crash in the driver, if not worse.

This has been the case since the inception of the
gallium copy of rtasm.

Jon TURNEY 87e84acbfd rtasm: The heap is NX on 64-bit Cygwin, so use the rtasm_exec_malloc() implementation which uses mmap()
The heap is NX on 64-bit Cygwin, so use the rtasm_exec_malloc() implementation
which uses mmap() to allocate an anonymous page with execute permission, rather
than the one which just uses malloc().

Kenneth Graunke 3d8d5b298a mesa: Restore 78-column wrapping of license text in C-style comments.
The previous commit introduced extra words, breaking the formatting.

This text transformation was done automatically via the following shell
command:
$ git grep 'THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY' | sed 's/:.*$//' | xargs -I {} sh -c 'vim -e -s {} < vimscript

where 'vimscript' is a file containing:
/THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY/;/\*\// !fmt -w 78 -p ' * '
:wq

Kenneth Graunke 96ff2edc73 mesa: Add "OR COPYRIGHT HOLDERS" to license text disclaiming liability.
This brings the license text in line with the MIT License as published
on the Open Source Initiative website:

http://opensource.org/licenses/mit-license.php

Generated automatically be the following shell command:
$ git grep 'THE AUTHORS BE LIABLE' | sed 's/:.*$//g' | xargs -I '{}' \
  sed -i 's/THE AUTHORS/THE AUTHORS OR COPYRIGHT HOLDERS/' {}

This introduces some wrapping issues, to be fixed in the next commit.

Kenneth Graunke dd404bc94f mesa: Change "BRIAN PAUL" to "THE AUTHORS" in license text.
Generated automatically be the following shell command:
$ git grep 'BRIAN PAUL BE LIABLE' | sed 's/:.*$//g' | xargs -I '{}' \
  sed -i 's/BRIAN PAUL/THE AUTHORS/' {}

The intention here is to protect all authors, not just Brian Paul.  I
believe that was already the sensible interpretation, but spelling it
out is probably better.

More practically, it also prevents people from accidentally copy &
pasting the license into a new file which says Brian is not liable when
he isn't even one of the authors.

Benjamin Close dbab39c6ca gallium: Add support for BSD operating systems, tested with FreeBSD
BSD supports pipe in the same way as linux hence options which
are safe for linux are also safe for BSD. Define PIPE_OS_BSD in
include/pipe/p_config.h and adjust the defines to make use of it.

Also define MAP_ANONYMOUS for BSD systems which use MAP_ANON

The debug functions depend on several util function for os abstractions, and

Brian Paul 8828d52348 gallium: fix alignment parameter passed to u_mmAllocMem()
Was 32, now 5.  The param is expressed as a power of two exponent.
The net effect is that the alignment was a no-op on X86 but on PPC we
always got the same memory address everytime rtasm_exec_malloc() was called.
