This patch series is a result of long debug work to find out why=0D
sometimes guests with win11 secure boot=0D
were failing during boot.=0D
=0D
During writing a unit test I found another bug, turns out=0D
that on rsm emulation, if the rsm instruction was done in real=0D
or 32 bit mode, KVM would truncate the restored RIP to 32 bit.=0D
=0D
I also refactored the way we write SMRAM so it is easier=0D
now to understand what is going on.=0D
=0D
The main bug in this series which I fixed is that we=0D
allowed #SMI to happen during the STI interrupt shadow,=0D
and we did nothing to both reset it on #SMI handler=0D
entry and restore it on RSM.=0D
=0D
V3: addressed most of the review feedback from Sean (thanks!)=0D
=0D
Best regards,=0D
