[PATCH 0/4] KVM: arm64: nv: Fixes for external abort exception routing

[Oliver Upton <oliver.upton@linux.dev>]

SEAs and SErrors come with a set of exception routing rules that are
potentially affected by EL2. KVM currently ignores these and just
injects the exceptions into the present context.

This series aims to address that, enlightening some of the injection
plumbing to the presence of vEL2. Additionally, patches 2 and 4 are
minor fixes for bugs that I found along the way.

Oliver Upton (4):
  KVM: arm64: nv: Respect exception routing rules for SEAs
  KVM: arm64: nv: Ensure Address size faults affect correct ESR
  KVM: arm64: nv: Honor SError exception routing / masking
  KVM: arm64: Treat vCPU with pending SError as runnable
