[PATCH] cpumask: bitmap cleanup preparation for cpumask overhaul
From: Paul Jackson <pj@sgi.com>
Document the bitmap bit model and handling of unused bits.
Tighten up bitmap so it does not generate nonzero bits in the unused tail if
it is not given any on input.
Add intersects, subset, xor and andnot operators. Change bitmap_complement to
take two operands.
Add a couple of missing 'const' qualifiers on bitops test_bit and bitmap_equal
args.
