and https://clang.llvm.org/docs/AttributeReference.html#alloc-align

Daniel Micay c6af50d088 use unsigned for ffzl definition 
This makes more sense and avoids clang tidy conversion warnings.
 2022-01-03 01:29:12 -05:00
Daniel Micay 8ae78237ae avoid unnecessarily mixing 32-bit and 64-bit ints 
It's ever so slightly faster to stick to stick to 64-bit arithmetic and
it avoids clang tidy being unhappy about the implicit widening.
 2022-01-03 00:54:43 -05:00
Daniel Micay 3f8e9d3184 make MREMAP_MOVE_THRESHOLD into size_t constant 
This avoids a clang-tidy warning and is a bit cleaner.
