nommu: remove __GFP_HIGHMEM in vmalloc/vzalloc
mm/nommu.c: void *__vmalloc(unsigned long size, gfp_t gfp_mask) { /* * You can't specify __GFP_HIGHMEM with kmalloc() since kmalloc() * returns only a logical address. */ return kmalloc(size, (gfp_mask | __GFP_COMP) & ~__GFP_HIGHMEM); } nommu's __vmalloc just uses kmalloc internally and elimitates __GFP_HIGHMEM, so it makes no sense to add __GFP_HIGHMEM for nommu's vmalloc/vzalloc.
