[PATCH v2 0/9] cleanup around kvm_sync_page, and a few micro-optimizations

From: Paolo Bonzini
Date: Mon Mar 07 2016 - 09:16:10 EST


Having committed the ubsan fixes, this are the cleanups that are left.

Compared to v1, I have fixed the patch to coalesce page zapping after
mmu_sync_children (as requested by Takuya and Guangrong), and I have
rewritten is_last_gpte again in an even simpler way.
