This patch series contains few nested SVM fixes from testing I did this weekend.
Patch #1 fixes issue where we were setting the GIF (global interrupt flag) on first nested VMexit, after migration thus making the nested guest crash from unexpected interrupts.
Patch #2 is my observation that we never setup nesed msr bitmap on nested state load after migration.
Patch #3 was 'migrated' ;-) from my other patch series to make it smaller, which is about more strict checks when we about to return to a nested guest, from SMM.
Best regards, Maxim Levitsky
