[PATCH v2 0/3] KVM: arm64: Read PMUVer as unsigned

[James Clark]

Fix some issues with the signedness of PMUVer and PerfMon ID fields.

I ran into the first issue when testing "ARM64 PMU Partitioning" patches
on the FVP. The second issue was only found by inspection.

Changes in v2:
- Handle ID_AA64DFR0_EL1_PMUVer_IMP_DEF correctly by using
  pmuv3_implemented()
- Fix another issue with incorrect sign in cpufeature.c
- Add a commit to refactor has_pmuv3() to use pmuv3_implemented() for
  consistency
- Link to v1: https://lore.kernel.org/r/20260305-james-kvm-pmuver-sign-v1-1-eea0a2116dd0@linaro.org
