Paolo Bonzini e74c3a8891 KVM/arm64 updates for 7.1
* New features:
 
 - Add support for tracing in the standalone EL2 hypervisor code,
   which should help both debugging and performance analysis.
   This comes with a full infrastructure for 'remote' trace buffers
   that can be exposed by non-kernel entities such as firmware.
 
 - Add support for GICv5 Per Processor Interrupts (PPIs), as the
   starting point for supporting the new GIC architecture in KVM.
 
 - Finally add support for pKVM protected guests, with anonymous
   memory being used as a backing store. About time!
 
 * Improvements and bug fixes:
 
 - Rework the dreaded user_mem_abort() function to make it more
   maintainable, reducing the amount of state being exposed to
   the various helpers and rendering a substantial amount of
   state immutable.
 
 - Expand the Stage-2 page table dumper to support NV shadow
   page tables on a per-VM basis.
 
 - Tidy up the pKVM PSCI proxy code to be slightly less hard
   to follow.
 
 - Fix both SPE and TRBE in non-VHE configurations so that they
   do not generate spurious, out of context table walks that
   ultimately lead to very bad HW lockups.
 
 - A small set of patches fixing the Stage-2 MMU freeing in error
   cases.
 
 - Tighten-up accepted SMC immediate value to be only #0 for host
   SMCCC calls.
 
 - The usual cleanups and other selftest churn.
