(bsc#1008340) Non security issues fixed :
Remove zlib module as requirement. (bsc#1020063)
Unlimit TaskMax for xfs_repair in emergency shell.
(bsc#1019938)
Resolve symbolic links for -i and -k parameters.
(bsc#902375)
Enhance purge-kernels script to handle kgraft patches.
(bsc#1017141)
Allow booting from degraded MD arrays with systemd.
(bsc#1017695)
Allow booting on s390x with fips=1 on the kernel command line. (bnc#1021687)
Start multipath services before local-fs-pre.target.
(bsc#1005410, bsc#1006118, bsc#1007925)
Fix /sbin/installkernel to handle kernel packages built with ‘make bin-rpmpkg’. (bsc#1008648)
