[GIT PULL] KVM/arm64 fixes for 5.19, take #1

[Marc Zyngier]

Hi Paolo,

Here's the first set of fixes for 5.19. Nothing major (one fix for the
GICv2 emulation, one for the embryonic protected VM support), the rest
being a bunch of small scale cleanup that I have decided to take now
rather than leaving them for later.

Please pull,

	M.

KVM/arm64 fixes for 5.19, take #1

- Properly reset the SVE/SME flags on vcpu load

- Fix a vgic-v2 regression regarding accessing the pending
  state of a HW interrupt from userspace (and make the code
  common with vgic-v3)

- Fix access to the idreg range for protected guests

- Ignore 'kvm-arm.mode=protected' when using VHE

- Return an error from kvm_arch_init_vm() on allocation failure

- A bunch of small cleanups (comments, annotations, indentation)
