Ard Biesheuvel 8439e62a15 arm64: mm: use bit ops rather than arithmetic in pa/va translations ... Since PAGE_OFFSET is chosen such that it cuts the kernel VA space right in half, and since the size of the kernel VA space itself is always a power of 2, we can treat PAGE_OFFSET as a bitmask and replace the additions/subtractions with 'or' and 'and-not' operations. For the comparison against PAGE_OFFSET, a mov/cmp/branch sequence ends up getting replaced with a single tbz instruction. For the additions and subtractions, we save a mov instruction since the mask is folded into the instruction's immediate field.
