Andrew, We're somehow new on this procedure. Are you referring to rebase this patch series to git://git.kernel.org/pub/scm/linux/kernel/git/next/linux- next.git <5.17-rc1 tag>?
Regards, Alex Sierra
Alex Deucher, Just a quick heads up. This patch series contains changes to the amdgpu driver which we're planning to merge through Andrew's tree, If that's ok with you.
No problem.
Thanks!
Alex
Regards, Alex Sierra

Some more reviewer input appears to be desirable here.
I was going to tentatively add it to -mm and -next, but problems. 5.17-rc1's mm/migrate.c:migrate_vma_check_page() is rather different from the tree you patched. Please redo, refresh and resend?
