[Juerg Haefliger]

https://ubuntu.com/security/CVE-2024-53114

https://warthogs.atlassian.net/browse/KCVE-1933

[ Impact ]

Random AMD Zen4 host reboots wen using virtualized VMLOAD/VMSAVE.


[ Test Case ]

Compile-tested only.


[ Where Problems Could Occur ]

CPU handling code, specific to AMD ZEN. Could result in problems
when booting AMD systems.


[ Notes ]

Older series are not affected. Newer series are already fixed.

v2:
  - Add additional commits identified during review:
    - 232afb557835d x86/CPU/AMD: Add X86_FEATURE_ZEN1
    - 15d6daad8f8ad tools headers x86 cpufeatures: Sync with the kernel
  - That area of the code was heavily refactored, pull in all those
    commits as well (which are tagged as non-functional changes) to ease
    future backports.
  - Pull in additional fixes for all of the above.
  - Add commits (partial backports) to sync the tools headers to not
    introduce new perf compile warnings (note that this does not fix any
    of the existing warnings, just makes sure no new ones are added).
