Intel said these patches will be in 5.11, and these patches could be 
changed before they are officially merged to upstream kernel. My plan is 
after the patches are merged to upstream, I will check hirsute/unstable 
kernel, if some patches are not in it, I will backport the upstreamed 
patch to hirsute/unstable.

Thanks.
