Rename the extisting runtime hweight() implementations to __arch_hweight(), rename the compile-time versions to __const_hweight() and then have hweight() pick between them. Suggested-by: NH.

Sam Ravnborg did the build-test that the direct header file move works, I'm just committing it. This is a pure move: mkdir arch/alpha/include git mv include/asm-alpha arch/alpha/include/asm with no other changes.

Implement __fls on all 64-bit archs: alpha has an implementation of fls64. Added __fls(x) = fls64(x) - 1. ia64 has fls, but not __fls. Added __fls based on code of fls. mips and powerpc have __ilog2, which is the same as __fls. Added __fls = __ilog2. parisc, s390, sh and sparc64: Include generic __fls. x86_64 already has __fls.

forbid asm/bitops.h direct inclusion Because of compile errors that may occur after bit changes if asm/bitops.h is included directly without e.g. linux/kernel.h which includes linux/bitops.h, forbid direct inclusion of asm/bitops.h.

Documentation/atomic_ops.txt defines these primitives must contain a memory barrier both before and after their memory operation. This is consistent with the atomic ops implementation on alpha.

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!
