Subject: Re: [RFC][PATCH v3 20/22] mm, avr32: add gfp flags variant of pte
 allocations


 - Added __pte_alloc_one_kernel to allocate page using specified GFP flag
 - Changed pte_alloc_one_kernel to call __pte_alloc_one_kernel newly added function using GFP_KERNEL allocation flag
 - Helps in fixing the Bug 30702
