Carlos' fix for a bug where KVM fails to signal #GP on emulated MOV DR to
DR4 or DR5, plus follow-up fixes priority goofs (#GP vs #DB, and #GP versus
#VMEXIT on SVM). The rest are opportunistic cleanups.

Carlos López (1):
KVM: x86: Treat any non-zero return from set_dr() as a faulting
condition
Sean Christopherson (5):
KVM: x86: Prioritize DR7.GD #DB over #GP due to illegal DR6/7 value
KVM: x86: Manually check DR4/5 write values to fix SVM intercept
priority
KVM: x86: Use kvm_dr{6,7}_valid() to check DR{4,5,6,7} write values in
emulator
KVM: x86: WARN if MOV DR emulation hits a "too late" #GP
KVM: x86: Read CR4.DE in emulator if and only if accessing DR4 or DR5
