From: Vlastimil Babka <vbabka@xxxxxxx>
Subject: mm, page_ext: periodically reschedule during page_ext_init()
page_ext_init() can take long on large machines, so add a cond_resched()
point after each section is processed. This will allow moving the init to
a later point at boot without triggering lockup reports.
