Subject: [RFT PATCH v2 0/2] Fix cross migration issue with missing
features: pdcm, arch-capabilities
X-Mailer: git-send-email 2.51.0
Add two compatibility properties to restore legacy behavior of machine types
prior to QEMU 10.1. Each of them addresses the two changes to CPUID:
- ARCH_CAPABILITIES should not be autoenabled when the CPU model specifies AMD
as the vendor
- specifying PDCM without PMU now causes an error, instead of being silently
dropped in cpu_x86_cpuid.
Note, I only tested this lightly.
Sorry for late.
I found the previous 2 fixes were merged into stable 10.0:

Yes, thanks for noticing it Zhao. Because we cannot apply the machine
type changes to 10.0, those two patches have to be reverted.
