      SoftPerfect RAM Disk 3.4.8, now working fine following CORE-9302

      https://www.majorgeeks.com/files/details/softperfect_ram_disk.html

      Create a new RAM drive (E:, 125 MB). Assert on mounting :

      (ntoskrnl/mm/freelist.c:196) ARM3-DEBUG: Being called with bffff ffffffffffffffff 0 7d01000 3 0
      *** Assertion failed: Pfn1
      ***   Source File: /srv/buildbot/worker_data/Build_GCCLin_x86/build/ntoskrnl/mm/freelist.c, line 320Break repeatedly, break Once, Ignore, terminate Process or terminate Thread (boipt)?
      kdb:> b
      Execute '.cxr F632358C' to dump contextEntered debugger on embedded INT3 at 0x0008:0x805AA7D2.kdb:> bt
      Eip:
      <ntoskrnl.exe:1aa7d2 (:0 (DbgUserBreakPoint))>
      Frames:
      <ntoskrnl.exe:ff30b (ntoskrnl/mm/freelist.c:320 (MiAllocatePagesForMdl))>
      <ntoskrnl.exe:bcc64 (ntoskrnl/mm/ARM3/mdlsup.c:497 (MmAllocatePagesForMdl))>
      <spvve.sys:e95b> 

      Same pattern as CORE-18917
