Greetings,
the first test patch to fix the pgtable_bytes mis-accounting on s390 still had a few problems. For one it didn't work for x86 ..
Changes v1 -> v2:
- Split the patch into three parts, one patch to add the mm_pxd_folded helpers, one patch to use to the helpers in mm_[dec|inc]_nr_[pmds|puds] and finally the fix for s390.
- Drop the use of __is_defined, it does not work with the __PAGETABLE_PxD_FOLDED defines
- Do not change the basic #ifdef'ery in mm.h, just add the calls to mm_pxd_folded to the pgtable_bytes accounting functions. This fixes the compile error on alpha (and potentially on other archs).
Martin Schwidefsky (3): mm: introduce mm_[p4d|pud|pmd]_folded mm: add mm_pxd_folded checks to pgtable_bytes accounting functions s390/mm: fix mis-accounting of pgtable_bytes
