This patch series is a result of long debug work to find out why sometimes guests with win11 secure boot were failing during boot. During writing a unit test I found another bug, turns out that on rsm emulation, if the rsm instruction was done in real or 32 bit mode, KVM would truncate the restored RIP to 32 bit. I also refactored the way we write SMRAM so it is easier now to understand what is going on. The main bug in this series which I fixed is that we allowed #SMI to happen during the STI interrupt shadow, and we did nothing to both reset it on #SMI handler entry and restore it on RSM.
I have now sent out the final/new version of the first 8 patches and will review these tomorrow. Thanks for your patience. :)
