Subject: Fix page allocation flags in grow_dev_page()
From: Christoph Lameter <clameter@xxxxxxx>
grow_dev_page() simply passes GFP_NOFS to find_or_create_page. This means
the allocation of radix tree nodes is done with GFP_NOFS and the allocation
of a new page is done using GFP_NOFS.
The mapping has a flags field that contains the necessary allocation flags
for the page cache allocation. These need to be consulted in order to get
DMA and HIGHMEM allocations etc right. And yes a blockdev could be
allowing Highmem allocations if its a ramdisk.
