Video input mux settings for tvp7002 and imager inputs were swapped.
Comment was correct.
Tested on EVM with tvp7002 input.

Commit 7416401 ("arm: davinci: Fix fallout from generic irq chip
conversion") introduced a bug, causing low level interrupt handlers to
get a bogus irq number as an argument. The gpio irq handler falsely
assumes that the handler data is the irq base number and that is no
longer true.
Set the irq handler data to be a pointer to the corresponding gpio
controller. The chained irq handler can then use it to extract both the
irq base number and the gpio registers structure.

I'm running a workload which triggers a lot of swap in a machine with 4
nodes. After I kill the workload, I found a kswapd livelock. Sometimes
kswapd3 or kswapd2 are keeping running and I can't access filesystem,
but most memory is free.
This looks like a regression since commit 08951e545918c159 ("mm: vmscan:
correct check for kswapd sleeping in sleeping_prematurely").
Node 2 and 3 have only ZONE_NORMAL, but balance_pgdat() will return 0
for classzone_idx. The reason is end_zone in balance_pgdat() is 0 by
default, if all zones have watermark ok, end_zone will keep 0.
Later sleeping_prematurely() always returns true. Because this is an
order 3 wakeup, and if classzone_idx is 0, both balanced_pages and
present_pages in pgdat_balanced() are 0. We add a special case here.
If a zone has no page, we think it's balanced. This fixes the livelock.

Assume that /sys/kernel/debug/dummy64 is debugfs file created by
debugfs_create_x64().
# cd /sys/kernel/debug
# echo 0x1234567812345678 > dummy64
# cat dummy64
0x0000000012345678
# echo 0x80000000 > dummy64
# cat dummy64
0xffffffff80000000
A value larger than INT_MAX cannot be written to the debugfs file created
by debugfs_create_u64 or debugfs_create_x64 on 32bit machine. Because
simple_attr_write() uses simple_strtol() for the conversion.
To fix this, use simple_strtoll() instead.

Don't update *inode in __follow_mount_rcu() until we'd verified that
there is mountpoint there. Kudos to Hugh Dickins for catching that
one in the first place and eventually figuring out the solution (and
catching a braino in the earlier version of patch).

`make headers_check` complains that
linux-2.6/usr/include/linux/sdla.h:116: userspace cannot reference
function or variable defined in the kernel
this is due to that there is no such a kernel function,
void sdla(void *cfg_info, char *dev, struct frad_conf *conf, int quiet);
I don't know why we have it in a kernel header, so remove it.

The WM8994 and WM8958 series of devices have two MICBIAS supplies rather
than one, the current widget actually manages the microphone detection
control register bit (which is managed separately by the relevant API).
Fix this, hooking the relevant supplies up to the MICBIAS1 and MICBIAS2
widgets.

same as in type 1 messages (i.e. keep the indicated capabilities same).
Some of the servers such as Samba, expect the flags such as
Negotiate_Key_Exchange in type 3 message of NTLMSSP exchange as well.
Some servers like Windows do not.

Another regression fix considering incomming l2cap connections with
defer_setup enabled. In situations when incomming connection is
extracted with l2cap_sock_accept, it's bt_sock info will have
'parent' member zerroed, but 'parent' may be used unconditionally
in l2cap_conn_start() and l2cap_security_cfm() when defer_setup
is enabled.

Bluetooth: Fix regression with incoming L2CAP connections
PTS test A2DP/SRC/SRC_SET/TC_SRC_SET_BV_02_I revealed that
( probably after the df3c3931e commit ) the l2cap connection
could not be established in case when the "Auth Complete" HCI
event does not arive before the initiator send "Configuration
request", in which case l2cap replies with "Command rejected"
since the channel is still in BT_CONNECT2 state.

disable it.

There is no software fallback implemented for SCTP or FCoE checksumming,
and so it should not be passed on by software devices like bridge or bonding.
For VLAN devices, this is different. First, the driver for underlying device
should be prepared to get offloaded packets even when the feature is disabled
(especially if it advertises it in vlan_features). Second, devices under
VLANs do not get replaced without tearing down the VLAN first.
This fixes a mess I accidentally introduced while converting bonding to
ndo_fix_features.
NETIF_F_SOFT_FEATURES are removed from BOND_VLAN_FEATURES because they
are unused as of commit 712ae51afd.

Packets to devices without NETIF_F_SCTP_CSUM (including NETIF_F_NO_CSUM)
should be properly checksummed because the packets can be diverted or
rerouted after construction. This still leaves packets diverted from
NETIF_F_SCTP_CSUM-enabled devices with broken checksums. Fixing this
needs implementing software offload fallback in networking core.
For users of sctp_checksum_disable, skb->ip_summed should be left as
CHECKSUM_NONE and not CHECKSUM_UNNECESSARY as per include/linux/skbuff.h.

As Simon reported, digital TV broke with mt20xx tuner due to
commit ad020dc2fe9039628cf6cef42cd1b76531ee8411.
The mt20xx tuner passes V4L2_TUNER_DIGITAL_TV to tuner core. However, the
check_mode code now doesn't handle it well. Change the logic there to
avoid the breakage, and fix a test for analog-only at g_tuner.

Attached is a patch which addresses a race condition in the DVB core
related to closing/reopening the DVB frontend device in quick
succession. This is the reason that devices such as the HVR-1300,
HVR-3000, and HVR-4000 have been failing to scan properly under MythTV
and w_scan.
The gory details of the race are described in the patch.
Devin
There is a race condition exhibited when channel scanners such as w_scan and
MythTV quickly close and then reopen the frontend device node.
Under normal conditions, the behavior is as follows:
1. Application closes the device node
2. DVB frontend ioctl calls dvb_frontend_release which sets
fepriv->release_jiffies
3. DVB frontend thread *eventually* calls dvb_frontend_is_exiting() which
compares fepriv->release_jiffies, and shuts down the thread if timeout has
expired
4. Thread goes away
5. Application opens frontend device
6. DVB frontend ioctl() calls ts_bus_ctrl(1)
7. DVB frontend ioctl() creates new frontend thread, which calls
dvb_frontend_init(), which has demod driver init() routine setup initial
register state for demod chip.
8. Tuning request is issued.
The race occurs when the application in step 5 performs the new open() call
before the frontend thread is shutdown. In this case the ts_bus_ctrl() call
is made, which strobes the RESET pin on the demodulator, but the
dvb_frontend_init() function never gets called because the frontend thread
hasn't gone away yet. As a result, the initial register config for the demod
is *never* setup, causing subsequent tuning requests to fail.
If there is time between the close and open (enough for the dvb frontend
thread to be torn down), then in that case the new frontend thread is created
and thus the dvb_frontend_init() function does get called.
The fix is to set the flag which forces reinitialization if we did in fact
call ts_bus_ctrl().
This problem has been seen on the HVR-1300, HVR-3000, and HVR-4000, and is
likely occuring on other designs as well where ts_bus_ctrl() actually strobes
the reset pin on the demodulator.
Note that this patch should supercede any patches submitted for the
1300/3000/4000 which remove the code that removes GPIO code in
cx8802_dvb_advise_acquire(), which have been circulating by users for some
time now...
