Hi Peter,
I see that you've added the HWEIGHT-capitalized interfaces for
compile-time constants with fce877e3. Which means, the bits in
<include/asm-generic/bitops/const_hweight.h> from your original patch at
http://lkml.org/lkml/2010/2/4/119 need changing (or have changed already
but I've missed them).
IOW, where can I get the current version of that last patch so that I can
base my __arch_hweightXX stuff ontop of it for testing?
Thanks.

Boris.
