------------------------------------------------------
Subject: SLUB: Extract finish_bootstrap function for clean !SYSFS boot
From: Christoph Lameter <clameter@xxxxxxx>

Extract finish_bootstrap function from slab_sysfs_init.  We can call that
function also if we do not have sysfs defined.  This enables embedded SMP
systems to have the periodic 30 second check for unused per cpu slabs.
