- kho: make memory preservation compatible with deferred initialization of
the memory map
- luo: add LIVEUPDATE_SESSION_GET_NAME ioctl and parameter verification for
LIVEUPDATE_IOCTL_CREATE_SESSION ioctl
- luo: documentation updates for liveupdate=on command line option, systemd
support and the current compatibility status
- luo: remove the fixed limits on the number of files that can be preserved
within a single session, and the total number of sessions managed by the
Live Update Orchestrator
- fixes that didn't cut as urgent and were delayed until the merge window:
* reference count incoming File-Lifecycle-Bound (FLB) data so it cannot
be freed while a subsystem is still using it
* fixes for a TOCTOU race in luo_session_retrieve(), a use-after-free in
the file finish and unpreserve paths, concurrent session mutations
during reboot and serialization on preserve_context kexec
* make sure ioctls for incoming LUO sessions are blocked for outgoing
sessions and vice versa
* make sure KHO scratch size is always aligned by CMA_MIN_ALIGNMENT_BYTES
* fix memblock tests build issue introduced by KHO changes

Pull liveupdate updates from Mike Rapoport:
"Kexec Handover (KHO):
- make memory preservation compatible with deferred initialization
of the memory map
Live Update Orchestrator (LUO):
- add LIVEUPDATE_SESSION_GET_NAME ioctl and parameter verification
for LIVEUPDATE_IOCTL_CREATE_SESSION ioctl
- documentation updates for liveupdate=on command line option,
systemd support and the current compatibility status
- remove the fixed limits on the number of files that can be
preserved within a single session, and the total number of
sessions managed by the LUO
Misc fixes:
- reference count incoming File-Lifecycle-Bound (FLB) data so
it cannot be freed while a subsystem is still using it
- fixes for a TOCTOU race in luo_session_retrieve(), a use-
after-free in the file finish and unpreserve paths, concurrent
session mutations during reboot and serialization on
preserve_context kexec
- make sure ioctls for incoming LUO sessions are blocked for
outgoing sessions and vice versa
- make sure KHO scratch size is always aligned by
CMA_MIN_ALIGNMENT_BYTES
- fix memblock tests build issue introduced by KHO changes"
