Subject: memory: make cpu_physical_memory_get_dirty() the main function
X-Git-Tag: Tizen_Studio_1.3_Release_p2.3.1~386^2~42^2~242^2~16
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9f2c43e41a13605d3ab1e37ba433aa669652fb6b;p=sdk%2Femulator%2Fqemu.git

memory: make cpu_physical_memory_get_dirty() the main function

And make cpu_physical_memory_get_dirty_flag() to use it.  It used to
be the other way around.
