[PATCH v3 00/17] KVM: arm64: nv: Support for EL2 PMU controls

[Oliver Upton <oliver.upton@linux.dev>]

Marc, I stole patch 1 from you for the sake of sending out a consistent
series. I can sort things out when I apply patches if that patch is a
common base for the both of us.

v2 -> v3:
 - Use the sysreg sanitisation infrastructure to apply RES0/RES1 masks
   to MDCR_EL2
 - Drop trap_config bit describing if a trap applies to Host EL0
 - Honor MDCR_EL2.{HPME,HLP} for the 'hypervisor range' of PMU counters

v2: https://lore.kernel.org/kvmarm/20240827002235.1753237-1-oliver.upton@linux.dev/#r
