Hello,
Two python bugfixes which definitely qualify for backport:
897257ba49d0 tools/python: change 's#' size type for Python >= 3.10
3a59443c1d5a tools/xenmon: Fix xenmon.py for with python3.x
Next, I'm going to argue for taking:
f7d07619d2ae x86/vmx: implement VMExit based guest Bus Lock detection
d329b37d1213 x86/vmx: introduce helper to set VMX_INTR_SHADOW_NMI
573279cde1c4 x86/vmx: implement Notify VM Exit
5f08bc9404c7 x86/vmx: Partially revert "x86/vmx: implement Notify VM Exit"
These are technically new features for Sapphire Rapids, but they're both
very simple (in the grand scheme of new features), and are both
mitigations to system-wide denial of services that required silicon
changes to make happen.
Either way, there is a security argument to be made for backporting these.
