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!
