Use explicit os-... in make dependencies instead of playing with symlinks
(symlink in question is still created - it's needed for other things; however,
there's no reason to complicate ordering here).

- Fix some problems with usage of $(targets) (sometimes missing, sometimes
used badly) that trigger partial rebuilds when doing a rebuild.
- At that purpose, also factor out some common code for symlinks creation.
- Fix a x86-64 build warning, caused by -L/usr/lib, which is anyway useless,
and invalid in the x86-64 case.
Tested on x86_64 and x86.

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).

These are some trivial fixes for the x86-64 subarch module support. The only
potential problem is that I have to modify arch/x86_64/kernel/module.c, to
avoid copying the whole of it.
I can't use it verbatim because it depends on a special vmalloc-like area for
modules, which for now (maybe that's to fix, I guess not) UML/x86-64 has not.
I went the easy way and reused the i386 vmalloc()-based allocator.

This patch does some totally trivial compilation fixes. It also restores the
debugregs manipulation, which was commented out simply because it doesn't
compile on x86_64 (we haven't yet implemented there debugregs handling).

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.

There were still a few comments left refering to verify_area, and two
functions, verify_area_skas & verify_area_tt that just wrap corresponding
access_ok_skas & access_ok_tt functions, just like verify_area does for
access_ok - deprecate those.
There was also a few places that still used verify_area in commented-out
code, fix those up to use access_ok.
After applying this one there should not be anything left but finally
removing verify_area completely, which will happen after a kernel release
or two.

Use the set_disk_ro() API when the backing file is read-only, to mark the disk
read-only, during the ->open(). The current hack does not work when doing a
mount -o remount.
Also, mark explicitly the code paths which should no more be triggerable (I've
removed the WARN_ON(1) things). They should actually become BUG()s probably
but I'll avoid that since I'm not so sure the change works so well. I gave it
only some limited testing.

Reuse asm-x86-64/unistd.h to build our syscall table, like x86-64 already
does.
Like for i386, we must add some #defines for all the (right!) changes UML does
to x86-64 syscall table.
Note: I noted a bogus:
[ __NR_sched_yield ] = (syscall_handler_t *) yield,
while doing this patch (which could only be a workaround for some strange bug,
but I would ignore this possibility). I'm changing this without notice.

Fix the moved syscall table for the x86_64 SUBARCH:
- redirect __NR_chown and such to versions aware of 32-bit UIDs,
- avoid the useless hack for sys_nfsservctl,
- use sys_sendfile64 in the table rather than sys_sendfile.
- __NR_uselib is sys_ni_syscall on x86_64 (which does not support A.OUT).
- __NR_getrlimit is sys_getrlimit, not sys_old_getrlimit

Split the i386 entry.S files into entry.S and syscall_table.S which is
included in the previous one (so actually there is no difference between them)
and use the syscall_table.S in the UML build, instead of tracking by hand the
syscall table changes (which is inherently error-prone).
We must only insert the right #defines to inject the changes we need from the
i386 syscall table (for instance some different function names); also, we
don't implement some i386 syscalls, as ioperm(), nor some TLS-related ones
(yet to provide).

We want to make possible, for the user, to enable the i586 AES implementation.
This requires a restructure.
- Add a CONFIG_UML_X86 to notify that we are building a UML for i386.
- Rename CONFIG_64_BIT to CONFIG_64BIT as is used for all other archs
- Tell crypto/Kconfig that UML_X86 is as good as X86
- Tell it that it must exclude not X86_64 but 64BIT, which will give the
same results.
- Tell kbuild to descend down into arch/i386/crypto/ to build what's needed.

This trick is useless, because sys_ni.c will handle this problem by itself,

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!
