Subject: [RFC][PATCH v2 03/23] (avr32) __vmalloc: add gfp flags variant of pte
 and pmd allocation

__vmalloc: propagating GFP allocation flag.

- adds functions to allow caller to pass the GFP flag for memory allocation
- helps in fixing the Bug 30702 (__vmalloc(GFP_NOFS) can callback
		  file system evict_inode).
