Hi Paolo and all,

Is it necessary to include the first patch (AVX10 cleanup/fix) in v9.2?

Others are for v10.0.

Compared with v4 [1],
 * patch 1 (AVX10 fix) and patch 9 (RAPL cleanup) are newly added.
 * rebased on commit 9a7b0a8618b1 ("Merge tag 'pull-aspeed-20241104' of
   https://github.com/legoater/qemu into staging").


Background and Introduction
===========================

This series picks cleanup from my previous kvmclock [2] (as other
renaming attempts were temporarily put on hold).

In addition, this series also include the cleanup on a historically
workaround, recent comment of coco interface [3] and error handling
corner cases in kvm_arch_init().

Avoiding the fragmentation of these misc cleanups, I consolidated them
all in one series and was able to tackle them in one go!
