  KVM: SEV-ES: reduce ghcb_sa_len to 32 bits (2021-10-18 06:49:26 -0400)

----------------------------------------------------------------
Tools:
* kvm_stat: do not show halt_wait_ns since it is not a cumulative statistic

x86:
* clean ups and fixes for bus lock vmexit and lazy allocation of rmaps
* avoid warning with -Wbitwise-instead-of-logical
* avoid warning due to huge kvmalloc.  Temporarily disables accounting,
  will be fixed in 5.16 and backported to stable 5.15
* two fixes for SEV-ES (one more coming as soon as I get reviews)
* fix for static_key underflow

ARM:
* Properly refcount pages used as a concatenated stage-2 PGD
* Fix missing unlock when detecting the use of MTE+VM_SHARED
