Preparation for pselect and ppoll.
ia32 compat code not tested. :-(

This fixes the setup of the alignment of the signal frame, so that all
signal handlers are run with a properly aligned stack frame.
The current code "over-aligns" the stack pointer so that the stack frame
is effectively always mis-aligned by 4 bytes. But what we really want
is that on function entry ((sp + 4) & 15) == 0, which matches what would
happen if the stack were aligned before a "call" instruction.
i386 and x86_64 are already fixed by d347f372273c2b3d86a66e2e1c94c790c208e166

Remove includes of <linux/smp_lock.h> where it is not used/needed.
Suggested by Al Viro.
Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

got the hint from Linus.

Removed IA64 architecture specific users of asm/segment.h
The removal of asm-ia64/segment.h itself can wait until all
of the kernel source has been purged of references.

Found by Alexander Nyberg, improved by Bjorn Helgaas.
- Fix the incorrect argument to sizeof()
- looks like memcpy() code pass was dervived from code that used
copy_from_user(). But in this case we are doing to kernel space
to kernel space copy, so memcpy is the right routine, but it
doesn't return an error code.

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!
