[NTOSKRNL]: Remove an ASSERT(FALSE) that was only there for testing. [NTOSKRNL]: Support transition pages during prototype PTE faults, which is our first try at soft faults! Should fix ASSERTs that were seen in the previous attempts in ole32, corrupting the registry. [NTOSKRNL]: It's fine for MiCreatePagingFileMap to fail in MmCreateSection -- don't assert and simply return failure. Should fix the ASSERTs taht were seen in KmTest. [NTOSKRNL]: Enable richard's ARM3 section code unconditionally for all non-file backed sections. Works4me. Let's see what Testbot says.
