Use the recently-added bio front_pad field to allocate struct dm_target_io.
Prior to this patch, dm_target_io was allocated from a mempool. For each
dm_target_io, there is exactly one bio allocated from a bioset.
This patch merges these two allocations into one allocation: we create a
bioset with front_pad equal to the size of dm_target_io so that every
bio allocated from the bioset has sizeof(struct dm_target_io) bytes
before it. We allocate a bio and use the bytes before the bio as
dm_target_io.
466e69b8b03b8c1987367912782bc12988ad8794 dropped busmaster enable from the
global drm code and moved it to the individual drivers, but missed the savage
driver. So, this re-adds busmaster enable to the savage driver, fixing the
regression.

Merge branch 'drm-next-3.7' of git://people.freedesktop.org/~agd5f/linux into drm-next
Alex writes:
"The big changes for 3.7 include:
- Asynchronous VM page table updates for Cayman/SI
- 2 level VM page table support. Saves memory compared to 1 level
page tables.
- Reworked PLL handing in the display code allows lots more
combinations of monitors to work, including more than two
DP displays assuming compatible clocks across shared PLLs.
This also allows us to power down extra PLLs when we can
share a single one across multiple displays which saves power.
- Native backlight control on ATOMBIOS systems.
- Improved ACPI support for interacting with the GPU. Fixes
backlight control on some laptops.
- Document AMD ACPI interfaces
- Lots of code cleanup
- Bug fixes"

This merge also removes a new use of __cancel_delayed_work(), and
replaces it with the regular cancel_delayed_work() that is now irq-safe

That said, I suspect the sequence in question should probably use
"mod_delayed_work()". I just did the minimal "don't use deprecated

workqueue: avoid using deprecated functions
The network merge brought in a few users of functions that got
deprecated by the workqueue cleanups: the 'system_nrt_wq' is now the
same as the regular system_wq, since all workqueues are now non-
reentrant.
Similarly, remove one use of flush_work_sync() - the regular
flush_work() has become synchronous, and the "_sync()" version is thus
deprecated as being superfluous.
Don't check MAY_WRITE as a newly created file may not have write mode bits,
but POSIX allows the creating process to write regardless.
This is ok because NFSv4 OPEN ops handle write permissions correctly -
the ACCESS in the OPEN compound is to differentiate READ v EXEC permissions.
Fixes a regression due to commit 6168f62c (NFSv4: Add ACCESS operation to
OPEN compound)
