  scsi-generic: do not do VPD emulation for sense other than ILLEGAL_REQUEST
  scsi-generic: avoid invalid access to struct when emulating block limits
  scsi-generic: avoid out-of-bounds access to VPD page list
  scsi-generic: keep VPD page list sorted
  lsi53c895a: check message length value is valid
  scripts/dump-guest-memory: Synchronize with guest_phys_blocks_region_add
  memory-mapping: skip non-volatile memory regions in GuestPhysBlockList
  nvdimm: set non-volatile on the memory region
  memory: learn about non-volatile memory region
  target/i386: Clear RF on SYSCALL instruction
  MAINTAINERS: remove or downgrade myself to reviewer from some subsystems
