__GFP_WAIT: If memory isn't avaible, sleep untill it is
__GFP_IO: We are allowed to do IO (eg swap).
__GFP_{LOW|MED|HI}: Relative necessity.
__GFP_DMA: Only allocate memory that we can DMA into (ie <16 MB on Intel
boxes)
the GFP_* flags are just combinations of the __GFP_* flags defined in
include/linux/mm.h. The order in __get_free_pages is the order of pages we
want (ie 2^order contigious pages. Order of 1 is equivlent to
__get_free_page().)
