From c8d6f66ae7d0ce5f3622c19e29a2333d28dc1e9a Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Mon, 17 Nov 2014 17:54:07 +0200 Subject: exec: cpu_physical_memory_set/clear_dirty_range Make cpu_physical_memory_set/clear_dirty_range behave symmetrically. To clear range for a given client type only, add cpu_physical_memory_clear_dirty_range_type. Signed-off-by: Michael S.
