The USB serial code was a new user of the kfifo API, and it was missed
when porting things to the new kfifo API.
Please make the write_fifo in place. Here is my patch to fix the
regression and full ported version.

We have to delay vfs_dq_claim_space() until allocation context destruction.
Currently we have following call-trace:
ext4_mb_new_blocks()
/* task is already holding ac->alloc_semp */
->ext4_mb_mark_diskspace_used
->vfs_dq_claim_space() /* acquire dqptr_sem here. Possible deadlock */
->ext4_mb_release_context() /* drop ac->alloc_semp here */
Let's move quota claiming to ext4_da_update_reserve_space()

The function ext3_mark_recovery_complete() is called from two call
paths: either (a) while mounting the filesystem, in which case there's
no danger of any other CPU calling write_super() until the mount is
completed, and (b) while remounting the filesystem read-write, in
which case the fs core has already locked the superblock. This also
allows us to take out a very vile unlock_super()/lock_super() pair in
ext3_remount().

ext3_fill_super() is no longer called by read_super(), and it is no
longer called with the superblock locked. The
unlock_super()/lock_super() is no longer present, so this comment is
entirely superfluous.

Currently inode_reservation is managed by fs itself and this
reservation is transfered on dquot_transfer(). This means what
inode_reservation must always be in sync with
dquot->dq_dqb.dqb_rsvspace. Otherwise dquot_transfer() will result
in incorrect quota(WARN_ON in dquot_claim_reserved_space() will be
triggered)
This is not easy because of complex locking order issues
for example http://bugzilla.kernel.org/show_bug.cgi?id=14739
The patch introduce quota reservation field for each fs-inode
(fs specific inode is used in order to prevent bloating generic
vfs inode). This reservation is managed by quota code internally
similar to i_blocks/i_bytes and may not be always in sync with
internal fs reservation.
Also perform some code rearrangement:
- Unify dquot_reserve_space() and dquot_reserve_space()
- Unify dquot_release_reserved_space() and dquot_free_space()
- Also this patch add missing warning update to release_rsv()
dquot_release_reserved_space() must call flush_warnings() as
dquot_free_space() does.

Effectively reverts 738d2be4301007f054541c5c4bf7fb6a361c9b3a.
As demonstrated by Eric, we really need to call __set_task_cpu()
early in the fork() path to properly initialize the various task
state -- specifically the cgroup state through set_task_rq().
[ we could probably fix this by explicitly calling
__set_task_cpu() from sched_fork(), but lets try that for the
next cycle and simply revert to the old behaviour for now. ]

This fixes LVDS on some mac laptops without a panel edid.
v2 - Set proper mode type flags
v3 - Note that this is not neceesarily the exact panel mode,
but an approximation based on the cvt formula. For these
systems we should ideally read the mode info out of the
registers or add a mode table, but this works and is much
simpler.
v4 - Update comments and debug message.

Because hardware cannot disable all colorbuffers directly to do depth-only
rendering, a user should:
- disable reading from a colorbuffer in blending
- disable fastfill
- set the color channel mask to 0 to prevent writing to a colorbuffer

Improve the command verifier to catch all occurences of surface handles,
and translate to SIDs.
This way DMA buffers and 3D surfaces share a common handle space,
which makes it possible for the kms code to differentiate.

Use kzalloc rather than kcalloc(1,...)
The use of the allocated memory that looks like an array is &p->relocs[0],
but this should be the same as p->relocs.
The semantic patch that makes this change is as follows:

linux/kernel.h has a "clamp" macro, but r300_cmdbuf also uses a variable
with the same name. Right now it doesn't seem to include the header,
but sooner or later someone will. So better rename the variable
now.
