- In success cases of NtAllocateVirtualMemory, return the real (page rounded!) base address and region size, not the possibly unaligned pointer and length which were passed to the function. These cases were hit when a region of memory was previously reserved, then a commit request came with unaligned base address and length, which match that previously reserved region after aligning.
