由 Juan Quintela 提交于 11月 05, 2013

If bitmaps are aligned properly, use bitmap operations.  If they are
not, just use old bit at a time code.

memory: make cpu_physical_memory_reset_dirty() take a length parameter · a2f4d5be

length parameter.

Once here, move the start/end calculation to
tlb_reset_dirty_range_all() as we don't need it here anymore.
