Last minute pullreq with one patch, fixing the GICv3 ICH_MISR_EL2.LRENP
calculation. I went back-and-forth on whether to put this in, but:
* it's an effective regression from 6.1 (the bug itself has been
present since before then, but it was previously masked by the
other bug which we fixed in 9cee1efe92)
* I just realized it could cause a screaming maintenance interrupt
even for hypervisors like KVM that don't set LRENPIE
On the other hand this is very late and we haven't seen it be a
problem with any guest except Qualcomm's hypervisor. So if you want
to decide it's better not going in that's OK too.
Tested on the gitlab CI and with a local test of nested KVM.
