[NTOS]
- Multiple ULONG -> SIZE_T fixes
- Use SLIST_ENTRY, not SINGLE_LIST_ENTRY in InterlockedPushEntrySList, they are not the same!
- Fix InterlockedCompareExchangePointer usage
- _1MB is 1024 KB, not 1000
- Rename PDE_SIZE to PD_SIZE to reflect it's purpose (size of a page directory, not a page directory entry)
- Add PD_COUNT, PDE_COUNT and PTE_COUNT for amd64 (should rather use PTE_PER_PAGE etc and move them to arch specific files.
- Some more PFN_TYPE -> PFN_NUMBER
