| |
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!
