Subject[PATCH 0/3] KVM: x86: cleanup and fixes for debug register accesses
Date
The purpose of this series is to get rid of the get_dr6 accessor
and, on Intel, of set_dr6 as well. This is done mostly in patch 2,
since patch 3 is only the resulting cleanup. Patch 1 is a related
bug fix that I found while inspecting the code.

A guest debugging selftest is sorely needed if anyone wants to take
a look!

KVM: SVM: fill in kvm_run->debug.arch.dr[67]
KVM: SVM: keep DR6 synchronized with vcpu->arch.dr6
