The commit 0f990222108d ("KVM: Check the allocation of pv cpu mask") we
have in 5.9-rc5 has two issue:
1) Compilation fails for !CONFIG_SMP, see:
https://bugzilla.kernel.org/show_bug.cgi?id=209285
2) This commit completely disables PV TLB flush, see
https://lore.kernel.org/kvm/87y2lrnnyf.fsf@xxxxxxxxxxxxxxxxxxxx/
The allocation problem is likely a theoretical one, if we don't
have memory that early in boot process we're likely doomed anyway.
Let's solve it properly later.
