The next phase of bitops cleanup.  This series:

 1) Untangles the mess around hweight()
 2) Removes some unwise uses of hweight()
 3) Makes it work transparently for RISC-V
 4) Use the POPCNT instruction on x86 when available

6 patches from the v2 posting has been committed.  See the remainder for v3
changes.

Andrew Cooper (5):
  xen/bitops: Reinstate the please tidy message
  xen/bitops: Drop the remnants of hweight{8,16}()
  xen/bitops: Implement hweight32() in terms of hweightl()
  xen/bitops: Implement hweight64() in terms of hweight{l,32}()
  x86/bitops: Use the POPCNT instruction when available
