How about pushing the call into cpu_physical_memory_set_dirty_flags()?
Would that reduce the number of call sites?

Pushing the calls to cpu_physical_memory_set_dirty_flags and
cpu_physical_memory_set_dirty_range would make the code much nicer.
However being these functions in exec-obsolete.h, are they at risk of

I thought about it, but when I saw that set_dirty were called only when it was not already set as dirty where the call seams to be necessary.

I just try to call xen_modified_mem only within cpu_phy_mem_set_dirty_flags but it does not work, even when I tried to clear the dirtybits. But I maybe don't do the right thing yet to clear the dirty bits
