Log:
[NTOSKRNL]
- Remove the BoundaryAddressMultiple parameter from MmCreateMemoryArea (wasn't used)
and give it instead a Granularity parameter
- Use the Granularity parameter in MmMapViewOfSegment to make sure that full sections are
allocated on a MM_ALLOCATION_GRANULARITY aligned address.
- Check for overflow and unaligned image base in MmMapViewOfSection when mapping image
sections
- Return proper status code on failure
