[PATCH v5 0/2] luo: convert serialized ptr to KHOSER_PTR

Convert raw serialized_data to KHO serializeable pointer (KHOSER_PTR).
This series also takes care of resolving the bug with memfd of using
phys_to_virt before checking the args->serialized_data value.

v5 <- v4
	separate the memfd_luo fix in a new commit to allow backport if
	needed.

v4 <- RESEND V3
	use only KHOSER_COPY_PTR and have compiler time check for type
	excluding void * types. Remove TYPE(UN)SAFE variants.
RESEND V3:
	Sent incorrect thread format earlier, this one is with correct
	one.
v3 <- v2
	Rebased on top of liveupdate/next
v2 <- v1
	Use KHOSER_PTR across liveupdate files instead of only memfd_luo

Tarun Sahu (3):
  mm/memfd_luo: validate serialized_data before conversion
  kho: add KHOSER_COPY_PTR to allow phys copy of serialized ptr
  luo: Update serialized data to use KHOSER_PTR
