What sparked these small patches is the series that fixed the PMU reset
values and their visibility from userspace, more specifically the
discussion around the patch that removed the PMSWINC_EL0 shadow register
[1].
The patches are straightforward cleanups without any changes in
functionality.
Tested on a rockpro64, by running kvm-unit-tests under qemu.
Changes in v2:
* Added patch #3 ("KVM: arm64: Replace get_raz_id_reg() with get_raz_reg()"), as
suggested by Drew.
* Rebased on top of v5.15-rc5.
* Gathered Reviewed-by, thanks!
* A few small commit message changes to patch #1.
