Greetings, this patch set of two adds memory change tracking alias soft-dirty feature to the s390 architecture. The first patch is a cleanup of the existing x86 support, it adds two arch specific functions pte_clear_soft_dirty and pmd_clear_soft_dirty to complement the other xxx_soft_dirty functions. This removes the use of a x86 specific function in fs/proc/tasm_mmu.c. The second patch is the s390 arch support. Tested on x86 and s390, seems to work as intended for both platforms. If the first patch is acceptable I can queue the set on the linux-s390 tree for the 4.4 merge window in a couple of weeks.
