[PATCH] pgtables: fix GFP_KERNEL allocation with preempt disabled

[Martin Hicks]

Hi Andrew,

This is a fix to the pgtable_quicklist code.  There is a GFP_KERNEL
allocation in pgtable_quicklist_alloc(), which spews the usual warnings
if the kernel is under heavy VM pressure and the reclaim code is
invoked.

This patch is against 2.6.12-rc2-mm2
