V4L/DVB (13097): cx23885: Complete CX23888 IR subdev implementation for Rx & almost for Tx
This change completes the v4l2_subdev implementation for IR receive for the
IR controller built into the CX23888.
This changes almost completes the IR transmit side also, but doesn't. Instead
notes in the comments describe what needs to be done for IR Tx to work in the
subdevice implementation.
The current Tx behavior is skeletal and benign. If left alone, it does nothing.
It will only ever generate a Tx interrupt on Tx init by a caller or when the
tx_write() method is called. The ISR, when called, will then disable the Tx
FIFO service interrupt.

Separate out the set_audclk_freq() function into separate functions for the

schemes and may be assuming slightly (+/- 3 Hz) different reference frequencies.
The code resuse was not worth the maintenance and testing headache of have all

bugs related to the shared code having a large number of conditional statements.

and CX2584[0123] cores and chips.
Also added code to identify a CX2388[578] A/V decoder core that is not
responding properly. Typical symptoms include registers 0x00-0xff
responding properly but all other registers returning the same value
(0x13 and 0x5 have been observed). This state will cause proper detection of
'885 vs. '887 vs. '888 to fail and the chip won't respond to get configured
properly anyway. I have no method of reseting the core to a working state at
this time; but I didn't try too hard to work one out either. The problem
likely only occurs in development. I suspect configuring the SYS PLL VCO to
oscillate too slowly (286.3 MHz?) before post divide may be the root cause,
when encountered.

2. possibly port it to the cx18 module for the CX23418 IR controller

This patch fixes some ref counting issues. Firstly by moving
the point at which we drop the ref count after a dlm lock
operation has completed we ensure that we never call
gfs2_glock_hold() on a lock with a zero ref count.
Secondly, by using atomic_dec_and_lock() in gfs2_glock_put()
we ensure that at no time will a glock with zero ref count
appear on the lru_list. That means that we can remove the

GFS2: drop rindex glock to refresh rindex list
When a gfs2 filesystem is grown, it needs to rebuild the rindex list to be able
to use the new space. gfs2 does this when the rindex is marked not uptodate,
which happens when the rindex glock is dropped. However, on a single node
setup, there is never any reason to drop the rindex glock, so gfs2 never
invalidates the the rindex. This patch makes gfs2 automatically drop the
rindex glock after filesystem grows, so it can refresh the rindex list.

GFS2: Tag all metadata with jid
There are two spare field in the header common to all GFS2
metadata. One is just the right size to fit a journal id
in it, and this patch updates the journal code so that each
time a metadata block is modified, we tag it with the journal
id of the node which is performing the modification.
The reason for this is that it should make it much easier to
debug issues which arise if we can tell which node was the
last to modify a particular metadata block.
Since the field is updated before the block is written into
the journal, each journal should only contain metadata which
is tagged with its own journal id. The one exception to this
is the journal header block, which might have a different node's
id in it, if that journal was recovered by another node in the
cluster.
Thus each journal will contain a record of which nodes recovered
it, via the journal header.
The other field in the metadata header could potentially be
used to hold information about what kind of operation was
performed, but for the time being we just zero it on each
transaction so that if we use it for that in future, we'll
know that the information (where it exists) is reliable.
I did consider using the other field to hold the journal
sequence number, however since in GFS2's journaling we write
the modified data into the journal and not the original
data, this gives no information as to what action caused the
modification, so I think we can probably come up with a better
use for those 64 bits in the future.

GFS2: Fix -o meta mounts for subsequent mounts (i.e. all but the first one)
We have a long term plan to use the "-o meta" flag to GFS2 mounts to
access the alternate root which is used to store metadata for a GFS2
filesystem. This will allow us to eventually remove support for the
gfs2meta filesystem type (which is in any case just a "front end" to
the gfs2 filesystem type with the meta/master root).
Currently the "-o meta" option is only taken into account on the
initial mount of the filesystem. Subsequent mounts of the same
filesystem (i.e. on the same device) result in basically the same
as bind mounting the root of the original mount.
This patch changes that by using what is more or less a copy
of get_sb_bdev() and extending it so that it will take into
account the alternate root in all cases. The main difference
is that we have to parse the mount options a bit earlier. We can
then use them to select the appropriate root towards the end of
the function.
In addition this also fixes a bug where it was possible (but certainly
not desirable) to set different ro/rw options for the meta root
when mounted via the gfs2meta fs compared with the original mount.

x86, Calgary IOMMU quirk: Find nearest matching Calgary while walking up the PCI tree
On a multi-node x3950M2 system, there's a slight oddity in the
PCI device tree for all secondary nodes:
30:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1)
\-33:00.0 PCI bridge: IBM CalIOC2 PCI-E Root Port (rev 01)
\-34:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04)
...as compared to the primary node:
00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1)
\-01:00.0 VGA compatible controller: ATI Technologies Inc ES1000 (rev 02)
03:00.0 PCI bridge: IBM CalIOC2 PCI-E Root Port (rev 01)
\-04:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04)
In both nodes, the LSI RAID controller hangs off a CalIOC2
device, but on the secondary nodes, the BIOS hides the VGA
device and substitutes the device tree ending with the disk
controller.
It would seem that Calgary devices don't necessarily appear at
the top of the PCI tree, which means that the current code to
find the Calgary IOMMU that goes with a particular device is
buggy.
Rather than walk all the way to the top of the PCI
device tree and try to match bus number with Calgary descriptor,
the code needs to examine each parent of the particular device;
if it encounters a Calgary with a matching bus number, simply
use that.
Otherwise, we BUG() when the bus number of the Calgary doesn't
match the bus number of whatever's at the top of the device tree.
Extra note: This patch appears to work correctly for the x3950
that came before the x3950 M2.

For RAM starved systems, TINY_RCU does not support CPU-stall detection
and is much smaller, but then again it is a uniprocessor...
