Return This is a common helper function for find_next_bit, find_next_zero_bit, and* find_next_and_bit. The differences are:* - The "invert" argument, which is XORed with each fetched word before* searching it for one bits.

cbm_validate_intel	Check whether a cache bit mask is valid. The SDM says:* Please note that all (and only) contiguous '1' combinations* are allowed (e.g. FFFFH, 0FF0H, 003CH, etc.).* Additionally Haswell requires at least two bits set.
