card has fewer channels. Also check for ioremap failure.

ringbuffer runs empty
Jan-Matthias Braun spotted a bug which locks up the driver when the
comedi ring buffer runs empty and provided a patch. The driver would
still send the data to comedi but the reader won't wake up any more.
What's required is setting the flag COMEDI_CB_BLOCK after new data has
arrived which wakes up the reader and therefore the read() command.

Yeeloong netbook has a sm712 video card, need this driver, but it is not
ready to upstream yet, so, go to drivers/staing at first.
This source code is originally from Silicon Motion Technology Corp, and
maintained at http://dev.lemote.com/code/linux_loongson for YeeLoong
netbook. I have done a lot of cleanups for it and merged it into my git
repository at http://dev.lemote.com/code/rt4ls.
Thanks to Simon for testing it on a little-endian x86 platform.
Thanks to Olivier Croset <olivier.croset@actis-computer.com> for
reporting the problem about __BIG_ENDIAN compiling problem and send a
relative patch.
The suspend/resume and blank support are contributed by Jason from
Silicon Motion Technology.

We create a file in orphan dir for reflink so that if there
is any error, we don't create any wrong dentry in the dir.
But actually the file in orphan dir should be i_nlink = 0
so that it can be replayed and freed successfully.
This patch first set i_nlink to 0 when creating the file in
orphan dir and then set it to 1(reflink now only works for
regular file) when we move it to the dest dir.

We used to add reflinked file's inode to inode hash when
we add it to the dest dir. But actually there is a race.
Consider the following sequence.
1. reflink happens and create the inode in orphan dir.
2. reflink thread is scheduled out because of some io.
3. recovery begins to work and calls ocfs2_recover_orphans.
It calls ocfs2_iget and get a new inode and i_count = 1.
It calls iput then and delete inode. the buffer's
uptodate state is cleared.
This patch move insert_inode_hash to the create function so
that it can be found by step 3 and prevented from deleting
because i_count > 1.
This resolves the bug

The reason is that if the ocfs2_extent_rec is the last record
in a leaf extent block, the old solution fails to find the
suitable end cpos. So this patch try to walk through the b-tree,
find the next sub root and get the c_pos the next sub-tree starts
from.
btw, I have runned tristan's test case against the patched kernel
for several days and this type of kernel panic never happens again.

Postpone the mixer name setup after the codec patch since the codec
patch may change the codec name string in itself.

I don't have an external mic or a SPDIF device to test the rest.

This patch fixes a bug where "virtual" registers were being written to the ac97
bus. This was causing unrelated registers to become corrupted (headphone 0x04,
touchscreen 0x78, etc).
This patch duplicates protection that was included in the wm9713 driver.

platform_get_irq returns -ENXIO on failure, so !irq was probably
always true. Better use (int)irq <= 0. Note that a return value of
zero is still handled as error even though this could mean irq0.
This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that
changed the return value of platform_get_irq from 0 to -ENXIO on error.

kernel-doc section header names (like "Note:") must be unique

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. ]

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()

Use a separate lock to protect s_groups_count and the other block
group descriptors which get changed via an on-line resize operation,
so we can stop overloading the use of lock_super().

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.
