David Howells b0e15190ea [PATCH] NOMMU: Make SYSV IPC SHM use ramfs facilities on NOMMU
The attached patch makes the SYSV IPC shared memory facilities use the new
ramfs facilities on a no-MMU kernel.

The following changes are made:

 (1) There are now shmem_mmap() and shmem_get_unmapped_area() functions to
     allow the IPC SHM facilities to commune with the tiny-shmem and shmem
     code.

 (2) ramfs files now need resizing using do_truncate() rather than by modifying
     the inode size directly (see shmem_file_setup()). This causes ramfs to
     attempt to bind a block of pages of sufficient size to the inode.

 (3) CONFIG_SYSVIPC is no longer contingent on CONFIG_MMU.

Greg Kroah-Hartman 712f47cea7 [PATCH] HOTPLUG: always enable the .config option, unless EMBEDDED
With modules, dynamic /dev, and uevents, people really want
CONFIG_HOTPLUG to be enabled in their kernels.  If not, they can still
disable it, but it is discouraged.

kobject_uevent.h header into the kobject.h header file.

David S. Miller a9c9dff1bc [SPARC64]: Stop putting -finline-limit=XXX into CFLAGS
It was a stupid workaround for the "static inline" vs.
"extern inline" issues of long ago, and it is what causes
schedule() to be inlined like crazy into kernel/sched.c
when -Os is specified.

MIPS and S390 should probably do the same.

Now CC_OPTIMIZE_FOR_SIZE can be safely used on sparc64
once more.

Linus Torvalds c45b4f1f1e Move size optimization option outside of EMBEDDED menu, mark it EXPERIMENTAL
Also, disable on sparc64 - a number of people report breakage.  Probably
a compiler bug, but it's quite possible that it tickles some latent
kernel problem too.

It still defaults to 'y' everywhere else (when enabled through
EXPERIMENTAL), and Dave Jones points out that Fedora (and RHEL4) has
been building with size optimizations for a long time on x86, x86-64,
ia64, s390, s390x, ppc32 and ppc64.  So it is really only moderately
experimental, but the sparc64 breakage certainly shows that it can
trigger "issues".

Linus Torvalds 0910b444bc Expose "Optimize for size" option for everybody
Let's put my money where my mouth is.  Smaller code is almost always
faster, if only because a single I$ miss ends up leaving a lot of cycles
to make up for.  And system software - kernels in particular - are known
for taking more cache misses than most other kinds.

On my random config, this made the kernel about 10% smaller, and lmbench
seems to say that it's pretty uniformly faster too. Your milage may vary.

Adrian Bunk 83bab9a4bb [PATCH] allow KOBJECT_UEVENT=n only if EMBEDDED
KOBJECT_UEVENT=n seems to be a common pitfall for udev users in 2.6.14 .

-mm already contains a bigger patch removing this option that is IMHO
too big for being applied now to 2.6.15-rc.

This patch simply allows KOBJECT_UEVENT=n only if EMBEDDED.

Ryan Anderson aaebf43320 [PATCH] kbuild: automatically append a short string to the version based upon the git commit
If CONFIG_AUTO_LOCALVERSION is set, the user is using a git-based tree, and the
current HEAD is not referred to by any tags in .git/refs/tags/, append -g and
the first 8 characters of the commit to the version string.  This makes it
easier to use git-bisect, and/or to do a daily build, without trampling on your
older, working builds, or accidentally setting up conflicting sets of modules.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
