Subject: [PATCH] S390: Replace calls to __get_free_pages() with __get_dma_pages().
Replace a number of calls to __get_free_pages() with the corresponding
calls to __get_dma_pages().
Signed-off-by: Robert P. J. Day <rpjday@...dspring.com>

once the __GFP_DMA argument is removed, it does look weird to see
the first argument of just 0. should that be filled in with
GFP_ATOMIC as christopher lameter suggested?
*not* compile tested.
