This patchset refactors/adds code to support writable per guest CPU ID
feature
registers. Part of the code/ideas are from

Hi Jing/Reiji,

Just to check the status on the above mentioned series "KVM: arm64: Make

CPU

quoted

ID registers writable by userspace". Is there any plan to respin that one

soon?

quoted

(Sorry, not sure there is any other series in progress for that support

currently)

I think this still is the latest, which I'm about to review again. I'd
appreciate if you could have a look to!

Thanks Marc for confirming. Will go through. We do have some requirement to
add support for Qemu CPU models/migration between different hosts.

Thanks,
Shameer
 

Thanks,

	M.
