      [POWERPC] Add flatdevtree source · 6fb4efc6
      由 Mark A. Greer 提交于 
      Add the latest version of the flatdevtree code and corresponding glue.

A phandle table now tracks values returned by ft_find_device().
The value returned by ft_find_device() is a phandle which is really
an index into the phandle table.  The phandle table contains the address
of the corresponding node.  When the flat dt is edited/moved, the node
pointers in the phandle table are updated accordingly so no phandles kept
by the caller become stale.

      [POWERPC] Create a "wrapper" script and use it in arch/powerpc/boot · 2bf11819
      由 Paul Mackerras 提交于 
      This puts the knowledge of how to create various sorts of zImage
wrappers into a script called "wrapper" that could be used outside of
the kernel tree.  This changes arch/powerpc/boot so it first builds
the files that the wrapper script needs, then runs it to create
whatever flavours of zImage are required.

This version does uImages as well.  The zImage names are changed
slightly; zImage.pseries is the one with the PT_NOTE program header
entry added, and zImage.pmac is the one without.  If the
zImage.pseries gets made, it will also get hardlinked to zImage;
otherwise, if zImage.pmac is made, it gets hardlinked to zImage.

      [PATCH] zlib_inflate: Upgrade library code to a recent version · 4f3865fb
      由 Richard Purdie 提交于 
      Upgrade the zlib_inflate implementation in the kernel from a patched
version 1.1.3/4 to a patched 1.2.3.

The code in the kernel is about seven years old and I noticed that the
external zlib library's inflate performance was significantly faster (~50%)
than the code in the kernel on ARM (and faster again on x86_32).

For comparison the newer deflate code is 20% slower on ARM and 50% slower
on x86_32 but gives an approx 1% compression ratio improvement.  I don't
consider this to be an improvement for kernel use so have no plans to
change the zlib_deflate code.

Various changes have been made to the zlib code in the kernel, the most
significant being the extra functions/flush option used by ppp_deflate.
This update reimplements the features PPP needs to ensure it continues to
work.

This code has been tested on ARM under both JFFS2 (with zlib compression
enabled) and ppp_deflate and on x86_32.  JFFS2 sees an approx.  10% real
world file read speed improvement.

This patch also removes ZLIB_VERSION as it no longer has a correct value.
We don't need version checks anyway as the kernel's module handling will
take care of that for us.  This removal is also more in keeping with the
zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've
added something to the zlib.h header to note its a modified version.

      [PATCH] ppc64: make arch/ppc64/boot standalone · decd300b
      由 Olaf Hering 提交于 
      Make the bootheader for ppc64 independent from kernel and libc headers.
* add -nostdinc -isystem $gccincludes to not include libc headers
* declare all functions in header files, also the stuff from string.S
* declare some functions static
* use stddef.h to get size_t (hopefully ok)
* remove ppc32-types.h, only elf.h used the __NN types

With further modifications by Paul Mackerras and Stephen Rothwell.

      Linux-2.6.12-rc2 · 1da177e4
      由 Linus Torvalds 提交于 
      Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
