[PATCH 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

- Make the NV init of the timers less awkward and expensive

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

Patches on top of kvmarm-6.14, 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: Consolidate NV configuration of virtual timers
