Nicolas Pitre f741a1aab5 [ARM] 3049/1: More optimized libgcc functions
Patch from Nicolas Pitre

This patch gets rid of the last C implementations of needed libgcc
functions for the kernel, replacing them with optimized assembly
versions.

Those functions are:

__ashldi3
__ashrdi3
__lshrdi3
__muldi3
__ucmpdi2

The first 3 were lifted from gcc, the other two were written from scratch.

Nicolas Pitre c09f98271f [ARM] 2930/1: optimized sha1 implementation for ARM
Patch from Nicolas Pitre

Here's an ARM assembly SHA1 implementation to replace the default C
version. It is approximately 50% faster than the generic C version. On
an XScale processor running at 400MHz:
	generic C version:	9.8 MB/s
	my version:		14.5 MB/s
This code is useful to quite a few callers in the tree:
crypto/sha1.c:		sha_transform(sctx->state, sctx->buffer, temp);
crypto/sha1.c:			sha_transform(sctx->state, &data[i], temp);
drivers/char/random.c:		sha_transform(buf, (__u8 *)r->pool+i, buf + 5);
drivers/char/random.c:	sha_transform(buf, (__u8 *)data, buf + 5);
net/ipv4/syncookies.c:	sha_transform(tmp + 16, (__u8 *)tmp, tmp + 16 + 5);

Seems to work fine on big-endian as well.

Russell King e7ec02938d [ARM SMP] Fix another ARMv6 bitop problem
We sometimes forgot to check whether the exclusive store succeeded.
Ensure that we always check.  Also ensure that we always use the
out of line versions, since the inline versions are not SMP safe.

Russell King 614d73edae [ARM SMP] Fix data corruption in test_* bitops
If we found that the bit was already in the desired state, we
would skip performing the operation, and write random data back.

Alexander Schulz b7523418f6 [PATCH] ARM: 2815/1: Shark: new defconfig, fixes with __io and serial ports
Patch from Alexander Schulz

This patch brings a new default config file for the shark and
fixes a compilation issue with io addressing and a runtime
problem with the serial ports, where I corrected a wrong
regshift value.
These are all shark specific files so I hope it is ok to
put them in one patch.

Nicolas Pitre c7e7887666 [PATCH] ARM: 2723/2: remove __udivdi3 and __umoddi3 from the kernel
Patch from Nicolas Pitre

Those are big, slow and generally not recommended for kernel code.
They are even not present on i386.  So it should be concluded that
one could as well get away with do_div() alone.

Russell King 684f970e2f [PATCH] ARM: bitops
Convert ARM bitop assembly to a macro.  All bitops follow the same
format, so it's silly duplicating the code when only one or two
instructions are different.

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!
