43f5b3085f uml: fix build when SLOB is enabled
Reintroduce uml_kmalloc for the benefit of UML libc code.  The
previous tactic of declaring __kmalloc so it could be called directly
from the libc side of the house turned out to be getting too intimate
with slab, and it doesn't work with slob.

So, the uml_kmalloc wrapper is back.  It calls kmalloc or whatever
that translates into, and libc code calls it.

kfree is left alone since that still works, leaving a somewhat
inconsistent API.

cb8fa61c2b uml: arch/um/drivers formatting
Style fixes for the rest of the drivers.  arch/um/drivers should be pretty
CodingStyle-compliant now.

Except for the ubd driver, which will have to be treated separately.

e99525f970 uml: console subsystem tidying
This does a lot of cleanup on the UML console system.  This patch should be
entirely non-functional.

The tidying is as follows:
	header cleanups - the includes should be closer to minimal and complete
	all printks now have a severity
	lots of style fixes
	fd_close is restructured a little in order to reduce the nesting
	some functions were calling the os_* wrappers when they can
call libc directly
	port_accept had a unnecessary variable
	it also tested a pid unecessarily before killing it
	some functions were made static
	xterm_free is gone, as it was identical to generic_free

e4c4bf9968 uml: Eliminate kernel allocator wrappers
UML had two wrapper procedures for kmalloc, um_kmalloc and um_kmalloc_atomic
because the flag constants weren't available in userspace code.
kern_constants.h had made kernel constants available for a long time, so there
is no need for these wrappers any more.  Rather, userspace code calls kmalloc
directly with the userspace versions of the gfp flags.

kmalloc isn't a real procedure, so I had to essentially copy the inline
wrapper around __kmalloc.

vmalloc also had its own wrapper for no good reason.  This is now gone.

fd9bc53b99 [PATCH] uml console channels: remove console_write wrappers
We were using a long series of (stupid) wrappers which all call
generic_console_write().  Since the wrappers only change the 4th param, which
is unused by the called proc, remove them and call generic_console_write()
directly.

If needed at any time in the future to reintroduce this stuff, the member
could be moved to a generic struct, to avoid this duplicated handling.

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!
