Hi Sean,
Below is the implementation to support 2M as you mentioned as option D.
It's based on UPM v7 xarray code: https://lkml.org/lkml/2022/7/6/259
Everything sounds good, the only trick bit is inc/dec disallow_lpage. If
we still treat it as a count, it will be a challenge to make the inc/dec
balanced. So in this patch I stole a bit for the purpose, looks ugly.
Any feedback is welcome.
Thanks,
Chao

Subject: [PATCH] KVM: Add large page support for private memory
Update lpage_info when handling KVM_MEMORY_ENCRYPT_{UN,}REG_REGION.
Reserve a bit in disallow_lpage to indicate a large page has
private/share pages mixed.
