| |
- Added function __pmd_alloc_one which is same as pmd_alloc_one, but accepts an extra argument for gfp_t flag.
- Added function __pte_alloc_one_kernel to allocated zeroed page using allocation flag passed as an argument.
- Changed pte_alloc_one_kernel to call __pte_alloc_one_kernel using GFP_KERNEL allocation flag.
- Helps in fixing the Bug 30702
