Subject: [PATCH 8/9] coalesce mmio regions without an explicit call
Date: Fri, 12 Sep 2008 12:10:49 -0300 [thread overview]
Message-ID: <1221232250-9653-9-git-send-email-glommer@redhat.com> (raw)
In-Reply-To: <1221232250-9653-1-git-send-email-glommer@redhat.com>
Try to coalesce mmio regions inside kvm_cpu_register_physical_memory().
Coalescing is done if area has TLB_MMIO flags set, or anything greater than that.
The original explicit function turns into an empty function. This is to be
bisection friendly. Direct calls are to be removed in a later commit.
