SubjectRe: [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
