Subject: [PATCH v1 0/2] s390/pgtable: misc small improvements

This series has two small improvements for the s390 page tables.

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 introduces _REGION3_ENTRY_HARDWARE_BITS_LARGE, for
completeness, which is a bitmask of the hardware bits for large puds.

Claudio Imbrenda (2):
  s390/pgtable: switch read and write softbits for puds
  s390/pgtable: introduce _REGION3_ENTRY_HARDWARE_BITS_LARGE
