[PATCH] include/linux/gfp.h cleanup for NUMA API

[Matthew Dobson]

Andi,
	Here's a few cleanups to include/linux/gfp.h

1) Move the extern of alloc_pages_current() into #ifdef CONFIG_NUMA. 
The only references to the function are in NUMA code in mempolicy.c

2) Remove the definitions of __alloc_page_vma().  They aren't used.

3) Move forward declaration of struct vm_area_struct to top of file.
