Hi!=0D

This patch series does some refactoring and implements on demand nested sta=
te area=0D
This way at least guests that don't use nesting won't waste memory=0D
on nested state.=0D
=0D
Patches 1,2,3 are refactoring=0D
=0D
Patches 4,5 are new from V1 and implement more strict SMM save state area c=
hecking=0D
on resume from SMM to avoid guest tampering with this area.=0D
=0D
This was done to avoid crashing if the guest enabled 'guest was interrupted=
'=0D
flag there and we don't have nested state allocated.=0D
=0D
Patches 6,7 are for ondemand nested state.=0D
=0D
The series was tested with various nested guests, in one case even with=0D
L3 running, but note that due to unrelated issue, migration with nested=0D
guest running didn't work for me with or without this series.=0D
I am investigating this currently.=0D

Best regards,=0D
