+Subject: [PATCH 353/354] Revert "sched/rt: Provide migrate_disable/enable()
+ inlines"
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=c127f3a8909b2dc34b7e211dba228ce6f63ec46c
+
+This reverts commit 56e8949825226341d28dd5156b3d0057684ff669.
+
+The tree contains already the migrate_disable/enable() helpers thus this
+stable backport conflicts (b) with the existing definition (compiler
+complains with conflicting definition). Thus we don't need this
+backported functions and can avoid the conflict by just dropping the
+backport.
