Subject: [PATCH v4 0/3] initialize deferred pages with interrupts enabled

Keep interrupts enabled during deferred page initialization in order to
make code more modular and allow jiffies to update.

Original approach, and discussion can be found here:

Changelog

  David Hildenbrand

v2:
- Addressed comments Daniel Jordan. Replaced touch_nmi_watchdog() to cond_resched().

v1:
https://lore.kernel.org/linux-mm/20200401193238.22544-1-pasha.tatashin@soleen.com

Daniel Jordan (1):
  mm: call touch_nmi_watchdog() on max order boundaries in deferred init

Pavel Tatashin (2):
  mm: initialize deferred pages with interrupts enabled
