- Add module option to force the display priority
0 = auto, 1 = normal, 2 = high
- Default to high on r3xx/r4xx/rv515 chips
Fixes flickering problems during heavy acceleration
due to underflow to the display controllers
- Fill in minimal support for RS600
v2 - update display priority when bandwidth is updated
so the user can change the parameter at runtime and it
will take affect on the next modeset.

- Drop some more safe regs taht userspace shouldn't hit
- Constant base regs need relocs. This allows us to use
constant buffers rather than the constant register file.
Also we don't want userspace to be able to set arbitrary
mc base values for the const caches.
- Track SQ_CONFIG so we know whether userspace is using
the cfile or constant buffers.

If the amount of free space left in a device is less than what we think should
be the minimum size, just ignore the minimum size and use the amount we have. I
ran into this running tests on a 600mb volume, the chunk allocator wouldn't let
me allocate the last 52mb of the disk for data because we want to have at least
64mb chunks for data. This patch fixes that problem. Thanks,

As Yan pointed out, theres not much reason for all this complicated math to
account for file extents being split up into max_extent chunks, since they are
likely to all end up in the same leaf anyway. Since there isn't much reason to
use max_extent, just remove the option altogether so we have one less thing we
need to test.

We don't actually check the return value of btrfs_read_block_groups, so we can
possibly succeed to mount, but then fail to say read the superblock xattr for
selinux which will cause the vfs code to deactivate the super.
This is a problem because in find_free_extent we just assume that we
will find the right space_info for the allocation we want. But if we
failed to read the block groups, we won't have setup any space_info's,
and we'll hit a NULL pointer deref in find_free_extent.
This patch fixes that problem by checking the return value of
btrfs_read_block_groups, and failing out properly. I've also added a
check in find_free_extent so if for some reason we don't find an
appropriate space_info, we just return -ENOSPC.

Commit 8ebc423238341b52912c7295b045a32477b33f09 (reiserfs: kill-the-BKL)
introduced a bug in the mount failure case.
The error label releases the lock before calling journal_release_error,
but it requires that the lock be held. do_journal_release unlocks and
retakes it. When it releases it without it held, we trigger a BUG().
The error_alloc label skips the unlock since the lock isn't held yet
but none of the other conditions that are clean up exist yet either.
This patch returns immediately after the kzalloc failure and moves
the reiserfs_write_unlock after the journal_release_error call.
This was reported in https://bugzilla.novell.com/show_bug.cgi?id=591807

Previously in interrupt handling tasklet, iwlwifi driver only clear/ack
those interrupts that are enabled by the driver through inta_mask.
If the hardware generates unattended interrupts, driver will not ack them,
defeating the interrupt coalescing feature. This results in high number
of interrupts per second and high CPU utilization.
This patch addresses this issue by acking those unattended interrupts
in the tasklet. Local test showed an order of magnitude improvement
in terms of the number of interrupts without sacrificing networking
throughput. This is a workaround for hardware issue.
