This series has two small improvements for the s390 page tables. they fix some small inconsistencies and missing things. The first aligns the layout of large puds with that of large pmds; there is no reason for the large pud read and write softbits to be swapped compared to large pmds. The second adds a few bits to _SEGMENT_ENTRY_BITS, _SEGMENT_ENTRY_HARDWARE_BITS and _SEGMENT_ENTRY_HARDWARE_BITS_LARGE; those bits are supposed to always be zero, the current code was working correctly since those bits were being ignored and always left set to zero. The patch also introduces _REGION3_ENTRY_HARDWARE_BITS and _REGION3_ENTRY_HARDWARE_BITS_LARGE, for completeness, which are the bitmasks of the hardware bits for normal puds and large puds. v3->v2 * update patch description for the second patch v2->v1 * add the missing pmd bits and _REGION3_ENTRY_HARDWARE_BITS Claudio Imbrenda (2): s390/pgtable: switch read and write softbits for puds s390/pgtable: add missing hardware bits for puds, pmds arch/s390/include/asm/pgtable.h | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) -- 2.44.0
