Patch 01 reverts the C-bit truncation patch as the reserved #PF was
confirmed to be due to a magic HyperTransport region (how many magic
addresses are there!?!). Hopefully the original patch simply be dropped,
but just in case...
Patch 02 reverts the C-bit clearing in the #NPF handler. If that somehow
turns out to be incorrect, i.e. there are flows where the CPU doesn't
mask off the C-bit, then it can be conditional on a SEV guest.
I'll be offline for the next two weeks, fingers crossed I've undone all
the damage. :-)
Thanks!
