[GIT PULL] KVM/arm64 updates for 5.13

Hi Paolo,

Here's the rather large pull request for 5.13. Changes are all over
the map, but the big ticket items are the S2 host isolation when
running in protected mode, the save/restore support for GICv4.1 and
guest SVE support in nVHE mode. Plenty of fixes too.

Note that this pull request drags a number of branches from other
trees in order to avoid conflicts and make people's life easier:

- the Coresight ETE/TRBE branch, as it is intertwined with the KVM
  tracing support

- the arm64 vhe-only branch that deals with broken CPUs such as the
  Apple M1

- the arm64 neon-softirqs-disabled that improves the support for
  FP processing

You will still get a couple of conflicts with the KVM tree, but these
are absolutely trivial to resolve.

Please pull,

	M.

  Merge branch 'kvm-arm64/kill_oprofile_dependency' into kvmarm-master/next (2021-04-22 13:41:49 +0100)

----------------------------------------------------------------
KVM/arm64 updates for Linux 5.13

New features:

- Stage-2 isolation for the host kernel when running in protected mode
- Guest SVE support when running in nVHE mode
- Force W^X hypervisor mappings in nVHE mode
- ITS save/restore for guests using direct injection with GICv4.1
- nVHE panics now produce readable backtraces
- Guest support for PTP using the ptp_kvm driver
- Performance improvements in the S2 fault handler
- Alexandru is now a reviewer (not really a new feature...)

Fixes:
- Proper emulation of the GICR_TYPER register
- Handle the complete set of relocation in the nVHE EL2 object
- Get rid of the oprofile dependency in the PMU code (and of the
  oprofile body parts at the same time)
- Debug and SPE fixes
- Fix vcpu reset
