From 59d8eb53ea9947db7cad8ebc31b0fb54f23a9851 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Tue, 10 Nov 2009 11:03:12 +0100 Subject: hw-breakpoints: Wrap in the KVM breakpoint active state check Wrap in the cpu dr7 check that tells if we have active breakpoints that need to be restored in the cpu. This wrapper makes the check more self-explainable and also reusable for any further other uses. Reported-by: Jan Kiszka Signed-off-by: Frederic Weisbecker Cc: Avi Kivity Cc: "K.
