Merge tag 'kvmarm-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64 updates for 7.0

- Add support for FEAT_IDST, allowing ID registers that are not
  implemented to be reported as a normal trap rather than as an UNDEF
  exception.

- Add sanitisation of the VTCR_EL2 register, fixing a number of
  UXN/PXN/XN bugs in the process.

- Full handling of RESx bits, instead of only RES0, and resulting in
  SCTLR_EL2 being added to the list of sanitised registers.

- More pKVM fixes for features that are not supposed to be exposed to
  guests.

- Make sure that MTE being disabled on the pKVM host doesn't give it
  the ability to attack the hypervisor.

- Allow pKVM's host stage-2 mappings to use the Force Write Back
  version of the memory attributes by using the "pass-through'
  encoding.

- Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the
  guest.

- Preliminary work for guest GICv5 support.

- A bunch of debugfs fixes, removing pointless custom iterators stored
  in guest data structures.

- A small set of FPSIMD cleanups.

- Selftest fixes addressing the incorrect alignment of page
  allocation.

- Other assorted low-impact fixes and spelling fixes.
