Description
generic_start_io_acct/generic_end_io_acct in the master
branch of the linux kernel requires that the request_queue
be provided.
Move the logic from freemem in the spl to arc_free_memory
in arc.c. Do this so we can take advantage of global_page_state
interface checks in zfs.
Upstream kernel replaced struct block_device with
struct gendisk in struct bio. Determine if the
function bio_set_dev exists during configure
and have zfs use that if it exists.
bio_set_dev torvalds/linux@74d4699
global_node_page_state torvalds/linux@75ef718

Motivation and Context
Port for release branch.
How Has This Been Tested?
Local testing, buildbot, ported from master.
