A couple of (char *) casts removed in a previous cleanup patch in
lib/string.c:memmove() were actually useful, as they suppressed a couple of
warnings:assignment discards qualifiers from pointer target type
Fix by declaring the local variable const in the first place, so casts
aren't needed to strip the const qualifier.Signed-off-by: Paul Jackson

The first two hunks of the patch really belongs in patch 1, but I missed
them on the first pass and instead of redoing all 3 patches I stuck them in
this one.Signed-off-by: Jesper Juhl

Removes a few pointless register keywords. register is merely a compiler
hint that access to the variable should be optimized, but gcc (3.3.6 in my
case) generates the exact same code with and without the keyword, and even
if gcc did something different with register present I think it is doubtful
we would want to optimize access to these variables - especially since this
is generic library code and there are supposed to be optimized versions in
asm/ for anything that really matters speed wise.(akpm: iirc, keyword register is a gcc no-op unless using -O0)

In include/asm-x86_64/string.h there are such comments:
/* Use C out of line version for memcmp */
#define memcmp __builtin_memcmp
int memcmp(const void * cs,const void * ct,size_t count);This would mean that if the compiler does not decide to use __builtin_memcmp,
it emits a call to memcmp to be satisfied by the C out-of-line version in
lib/string.c. What happens is that after preprocessing, in lib/string.i you
may find the definition of "__builtin_strcmp".Actually, by accident, in the object you will find the definition of strcmp
and such (maybe a trick intended to redirect calls to __builtin_memcmp to the
default memcmp when the definition is not expanded); however, this particular
case is not a documented feature as far as I can see.Also, the EXPORT_SYMBOL does not work, so it's duplicated in the arch.
I simply added some #undef to lib/string.c and removed the (now duplicated)
exports in x86-64 and UML/x86_64 subarchs (the second ones are introduced by
another patch I just posted for -mm).Signed-off-by: Paolo 'Blaisorblade' Giarrusso

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!
