Subject: [PATCH 0/4] KVM: nested x86: nested page faults fixes
Date: Tue,  2 Sep 2014 17:13:46 +0200	[thread overview]
Message-ID: <1409670830-14544-1-git-send-email-pbonzini@redhat.com> (raw)

Patch 1 implements AMD semantics for non-leaf PDPEs and PML4Es, which
are a bit different from Intel.  The SVM test relies on this, so fix it.

Patch 2 lets nested SVM implement nested page fault correctly.  We were
not setting bits 32/33.

Patches 3 and 4 fix the interaction between emulator and nested EPT/NPT,
which was reported by Valentine.

Reviews are very welcome, I'm walking on thin ice here...

Paolo

Paolo Bonzini (4):
  KVM: x86: reserve bit 8 of non-leaf PDPEs and PML4Es in 64-bit mode on AMD
  KVM: nSVM: propagate the NPF EXITINFO to the guest
  KVM: x86: inject nested page faults on emulated instructions
  KVM: x86: propagate exception from permission checks on the nested page fault
