[PATCH v2 0/3] KVM/arm64: timer fixes for 6.14

[Marc Zyngier <maz@kernel.org>]

It's been recently pointed out that the NV timer code that is
(hopefully) on its way upstream is marginally sub-optimal (read:
terminally broken). This short series attempts to fix things:

- Correctly arm a background timer in all situations

- Avoid corrupting the EL2 state by shoving the EL1 state into it, and
  simplify the handling of emulated timers

- Drop the weird HV timer offset dance dance on E2H switch that never
  happens and make HV timer correctly UNDEF on E2H==0.

Thanks to Volodymyr Babchuk and Wei-Lin Chang for their help.

Patches on top of kvmarm/fixes, and merged back on top of my
kvm-arm64/nv-next branch.

Marc Zyngier (3):
  KVM: arm64: timer: Always evaluate the need for a soft timer
  KVM: arm64: timer: Correctly handle EL1 timer emulation when !FEAT_ECV
  KVM: arm64: timer: Don't adjust the EL2 virtual timer offset
