[PATCH 05/28] KVM: arm64: Plumb HCRX_EL2.SRMASKEn in HCRX_EL2 sanitisation

[Marc Zyngier]

HCRX_EL2.SRMASKEn is a new bit enabling FEAT_SRMASK for a guest.
We don't plan to support it any time soon, but it doesn't hurt to
actively document it, specially as we are going to add more bits
we actually care about.
