Martin Schwidefsky 152125b7a8 s390/mm: implement dirty bits for large segment table entries
The large segment table entry format has block of bits for the
ACC/F values for the large page. These bits are valid only if
another bit (AV bit 0x10000) of the segment table entry is set.
The ACC/F bits do not have a meaning if the AV bit is off.
This allows to put the THP splitting bit, the segment young bit
and the new segment dirty bit into the ACC/F bits as long as
the AV bit stays off. The dirty and young information is only
available if the pmd is large.

uapi/asm A bunch of one-liners (except the s390 one). 2014-07-01 09:27:34 -07:00
