Through reading debug related codes in kvm/x86, I found the flags of
switch_db_regs is a little confusing (at least for me) and there is
something to improve. So this patchset comes. But it only go througg
compilation.

Xiaoyao Li (3):
  kvm: x86: Rename KVM_DEBUGREG_RELOAD to KVM_DEBUGREG_NEED_RELOAD
  kvm: x86: Use KVM_DEBUGREG_NEED_RELOAD instead of
    KVM_DEBUGREG_BP_ENABLED
  kvm: x86: skip DRn reload if previous VM exit is DR access VM exit
