Pull hweight type fix from Ingo Molnar:
"This lone commit makes sure that __const_hweight8() is unsigned, which
addresses a build warning if code is built with -Wsign-compare.
I hope the type cast in this cleanup is fine - another option would be
to eliminate the double unary negation and use a construct with more
obvious integer type characteristics, along the lines of:
((w) & (1ULL << 1) ? 1U : 0U)
or so"
