[PATCH 0/2] KVM: arm64: Control visibility of S1PIE related sysregs to userspace

From: Mark Brown
Date: Wed Aug 21 2024 - 09:14:57 EST


While looking at the KVM system register code I noticed that we do not
have visibility operations for TCR2 or the S1PIE registers, I may be
missing some reason why they are not required but in case I'm not I
figured the most direct way to ask was to propose adding the operations.
