The patch titled
s390: fix ipd handling
has been added to the -mm tree. Its filename is
s390-fix-ipd-handling.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
From: Heiko Carstens <heiko.carstens@xxxxxxxxxx>
As pointed out by Paulo Marques <pmarques@xxxxxxxxxxxx> MAX_IPD_TIME is by
a factor of ten too small. Since this means that we allow ten times more
IPDs in the intended time frame this could result in a cpu check stop of a
physical cpu.
