[GIT PULL] KVM/arm64 fixes for 6.16, take #4

[Marc Zyngier]

Paolo,

Another week, another set of fixes. Nothing major this time: allow
pKVM to fail to initialise without taking the host down, make sure we
are not mapping too much in the host S2 (another pKVM special), and a
brown-paper-bag quality bug fix on the nested GICv3 emulation.

Please pull,

	M.
