Merge tag 'liveupdate-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull liveupdate updates from Mike Rapoport:
 "Kexec Handover:

   - Fix size calculation in kho_preserved_memory_reserve() for
     preservations larger than 2 GiB

  Live Update Orchestrator:

   - move liveupdate selftest utilities into a library so that selftests
     of subsystems participating in liveupdate, e.g. PCI and VFIO, can
     use them and drop direct ioctl calls from the tests

   - add end to end liveupdate test infrastructure that allows running
     the tests across a kexec in QEMU

   - remove redundant INIT_LIST_HEAD in luo_session_alloc()

   - remember the error status of an FLB retrieve() and return it on
     subsequent attempts rather than retrying retrieve() with an FLB in
     an unexpected state

   - reference count the outgoing FLB so that it cannot be freed while a
     caller is using it, the same way it's done for the incoming FLB

   - reject nonzero reserved field in LIVEUPDATE_SESSION_FINISH so that
     it can be reused by a future extension"
