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->v4
* fix order of _REGION3_ENTRY_HARDWARE_BITS* macros to be the same as
  the _SEGMENT_ENTRY_HARDWARE_BITS* macros
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
