Vladimir Murzin cb96408da4 arm64: KVM: VHE: reset PSTATE.PAN on entry to EL2 ... SCTLR_EL2.SPAN bit controls what happens with the PSTATE.PAN bit on an exception. However, this bit has no effect on the PSTATE.PAN when HCR_EL2.E2H or HCR_EL2.TGE is unset. Thus when VHE is used and exception taken from a guest PSTATE.PAN bit left unchanged and we continue with a value guest has set. To address that always reset PSTATE.PAN on entry from EL1.
