From 152125b7a882df36a55a8eadbea6d0edf1461ee7 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Thu, 24 Jul 2014 11:03:41 +0200 Subject: [PATCH] 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. Signed-off-by: Martin Schwidefsky --- Reading git-format-patch failed
