Do you need to know the large page size outside of `Memory.inc`? If no, you could mark it as a static function, in the same way as the Windows `enableProcessLargePages()` (which detects the minimum large page size). Additionally, you can also take a look at how rpmalloc does it: `rpmalloc.c, L1802-L1871` in D71786 <https://reviews.llvm.org/D71786>, as it already handles the same platforms as LLVM.
