Subject: [PATCH 0/4] KVM: x86: nVMX: Nested PML bug fix and cleanup
Date: Mon, 22 Jun 2020 14:58:28 -0700 [thread overview]
Message-ID: <20200622215832.22090-1-sean.j.christopherson@intel.com> (raw)
Fix for a theoretical bug in nested PML emulation, and additional clean up
of the related code.
Tested by doing a few rounds of intra-VM migration (same L1) of an L2
guest with PML confirmed enabled in L1.
This has a trivial conflict with patch 3 of the MMU files series[*], both
remove function prototypes from mmu.h.
