| |
- Added __pud_alloc_one which allows caller to specify the gfp_t flag. Like pud_alloc_one the function calls quicklist_alloc() and passes the given allocation flag.
- Changed pud_alloc_one to call __pud_alloc_one using GFP_KERNEL.
- Added similar changes for pte and pmd allocation functions.
- Helps in fixing the Bug 30702.
