Subject: Re: [RFC][PATCH v3 08/22] mm, score: add gfp flags variant of pte
 allocations


- Added __pte_alloc_one_kernel() function to allocate zeroed pages using
   passed allocation flag. The function pte_alloc_one_kernel() is changed to
   call __pte_alloc_one_kernel() passing GFP_KERNEL | __GFP_REPEAT allocation
   flags.

- Helps in fixing the Bug 30702
