Merge branch kvm-arm64/nv-resx-fixes-6.14 into kvmarm-master/next

* kvm-arm64/nv-resx-fixes-6.14:
  : .
  : Fixes for NV sysreg accessors. From the cover letter:
  :
  : "Joey recently reported that some rather basic tests were failing on
  : NV, and managed to track it down to critical register fields (such as
  : HCR_EL2.E2H) not having their expect value.
  :
  : Further investigation has outlined a couple of critical issues:
  :
  : - Evaluating HCR_EL2.E2H must always be done with a sanitising
  :   accessor, no ifs, no buts. Given that KVM assumes a fixed value for
  :   this bit, we cannot leave it to the guest to mess with.
  :
  : - Resetting the sysreg file must result in the RESx bits taking
  :   effect. Otherwise, we may end-up making the wrong decision (see
  :   above), and we definitely expose invalid values to the guest. Note
  :   that because we compute the RESx masks very late in the VM setup, we
  :   need to apply these masks at that particular point as well.
  : [...]"
