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.

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.

drivers/block/ is right now a mix of core and driver parts. Lets move
the core parts to a new top level directory. Al will move the fs/
related block parts to block/ next.

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.

Move initramfs options from Device Drivers | Block Drivers to General Setup
This is a more natural place for this option.
Furthermore separate out intramfs options to usr/Kconfig

Actually, the real support was added by some earlier patches. Now we simply
re-enable the config. option. I've actually tested it and it works well.

Audit now actually requires netlink. So make it depend on CONFIG_NET,
and remove the inline dependencies on CONFIG_NET.

This patch is for -mm only. It should probably be included in git-audit,
and should be forwarded to Linus iff git-audit is.
It updates the audit-syscall-{entry,exit} calls to current -mm.

Arrange for all kernel printks to be no-ops. Only available if
CONFIG_EMBEDDED.
This patch saves about 375k on my laptop config and nearly 100k on minimal

This patch eliminates all kernel BUGs, trims about 35k off the typical
kernel, and makes the system slightly faster.

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!
