The patch titled mm: disable preemption in apply_to_pte_range has been removed from the -mm tree. Its filename was mm-disable-preemption-in-apply_to_pte_range.patch This patch was dropped because it was nacked The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: mm: disable preemption in apply_to_pte_range From: Jeremy Fitzhardinge <jeremy@xxxxxxxx> Lazy mmu mode needs preemption disabled, so if we're apply to init_mm (which doesn't require any pte locks), then explicitly disable preemption. (Do it unconditionally after checking we've successfully done the allocation to simplify the error handling.)
