[PATCH 0/2] KVM: arm64: Simplify handling of GICv3 hardware with broken SEIS

[Will Deacon]

Hi folks,

While looking at reducing the host memory mapped into pKVM at EL2, I
noticed that the GICv3 CPU interface emulation for hardware with broken
SEIS implementations can be simplified and the corresponding mapping of
'kvm_vgic_global_state' can be dropped.

Please have a look!

Cheers,

Will
