The patch titled
Subject: mm, slub: don't disable irqs in slub_cpu_dead()
has been removed from the -mm tree. Its filename was
mm-slub-dont-disable-irqs-in-slub_cpu_dead.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Vlastimil Babka <vbabka@xxxxxxx>
Subject: mm, slub: don't disable irqs in slub_cpu_dead()
slub_cpu_dead() cleans up for an offlined cpu from another cpu and calls
only functions that are now irq safe, so we don't need to disable irqs
anymore.
