D Scott Phillips	f878200180	bitset: add BIT_FFS_AT() for finding the first bit set greater than a start bit ... Reviewed by: kib Approved by: scottl (implicit) MFC after: 1 week Sponsored by: Ampere Computing, Inc. Differential Revision: https://reviews.freebsd.org/D26128	2020-08-26 02:07:46 +00:00
Ryan Libby	9825eadf2c	bitset: rename confusing macro NAND to ANDNOT ... s/BIT_NAND/BIT_ANDNOT/, and for CPU and DOMAINSET too. The actual implementation is "and not" (or "but not"), i.e. A but not B. Fortunately this does appear to be what all existing callers want. Don't supply a NAND (not (A and B)) operation at this time.

Konstantin Belousov	1550c62236	Add BIT_FLS() analogous to BIT_FFS(). ... The benefit of BIT_FLS() is that ffsl() can be implemented with a count leading zeros instruction which is more widespread available.
