Contention when updating a page table entry can lead to unnecessary refaults. The issue was reported by a user when testing PUD hugepage support[1] but also exists for PMD and PTE updates though with a lower probability.
This version -
* fixes a nit reported by Suzuki * Re-orders the checks when setting PMD hugepage * drops mistakenly introduced Change-id in the commit message
Thanks, Punit
