Subject: [GIT PULL] KVM/arm64 fixes for 6.6, take #2

 Paolo,

Here's a set of additional fixes for 6.6. The most important part is
the fix for a breakage of the Permission Indirection feature, which is
a regression. The other (less important) part is a fix for the physical
timer offset.

Please pull,

        M.
