Merge branch 'core-types-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

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"
