[PATCH 0/6] KVM: arm64: More PMU/debug ID register fixes

This is a respin of a series I posted in the 5.7 time frame, and
completely forgot about it until I noticed again that a few things
where not what I remembered... Given how long it has been, I'm
pretending this is v1 again.

Anyway, this covers a few gaps in our ID register handling for PMU and
Debug, plus the upgrade of the PMU support to 8.4 when possible.

I don't plan to take this into 5.11, but this is a likely candidate
for 5.12.

Marc Zyngier (6):
KVM: arm64: Fix missing RES1 in emulation of DBGBIDR
KVM: arm64: Fix AArch32 PMUv3 capping
KVM: arm64: Add handling of AArch32 PCMEID{2,3} PMUv3 registers
KVM: arm64: Refactor filtering of ID registers
KVM: arm64: Limit the debug architecture to ARMv8.0
KVM: arm64: Upgrade PMU support to ARMv8.4
