When a break signal is detected, the next character should be ignored.
This was not implemented correctly for the pnx8xxx_uart driver.
[From further discussion:
Correct, you can look to it as two separate bugs:
a) the next character is not ignored while it should;
b) the status bits 31-8 are copied to the 'ch' variable while they shouldn't.
Both bugs prevent correct break signal handling (and therefore correct
behaviour of the magic SysRq key). Bug b didn't cause too much trouble
earlier because in most situations the status bits are all zero; for
this case they unfortunately aren't.

For UID grouping we initialize the root group with infinite bandwidth
which by default is actually more than the global limit, therefore the
bandwidth check always fails.
Because the root group is a phantom group (for UID grouping) we cannot
runtime adjust it, therefore we let it reflect the global bandwidth
settings.

sound: virtuoso: do not overwrite EEPROM on Xonar D2/D2X
On the Asus Xonar D2 and D2X models, the SPI chip select signal for the
fourth DAC shares its pin with the serial clock for the EEPROM that
contains the PCI subdevice ID values. It appears that when DAC
registers are written and some other unknown conditions occur (probably
noise on the EEPROM's chip select line), the EEPROM gets overwritten
with garbage, which makes it impossible to properly detect the card
later.
Therefore, we better avoid DAC register writes and make sure that the
driver works with the DAC's registers' default values. Consequently,
the sample format is now I2S instead of left-justified (no user-visible
change), and the DAC's volume/mute registers cannot be used anymore
(volume changes are now done by the software volume plugin).

When an i4l ppp interface is shut down (e.g. with /sbin/ifdown ippp0) a
scary warning is logged:
isdn_free_channel: called with invalid drv(-1) or channel(-1)
This warning is caused by isdn_net_unbind_channel(), which always calls
isdn_free_channel() even if isdn_net_local->isdn_device and
isdn_net_local->isdn_channel are (still) in a perfectly acceptable
default state, so let's not do that.

PHYID returns 0xffff and not 0xffffffff when not found and in some
case(at91sam9263) 0x0. Maybe this patch could be useful.
phy_device.c treats PHY ID == 0x0 as bogus IDs, and that results in
gianfar driver failure to see the TBI PHYs. This code snippet triggers:
if (!priv->tbiphy) {
printk(KERN_WARNING "SGMII mode requires that the device "
"tree specify a tbi-handle\n");
return;
}
Although tbi-handle is specified in the device tree.
Btw, technically PHY ID == 0x0 is a valid ID (if we ever see a PHY
manufactured by Xerox :-).

gro: Check for GSO packets and packets with frag_list
As GRO cannot be applied to packets with frag_list we need to
make sure that we reject such packets if they are fed to us,
e.g., through a tunnel device.
Also there is no point in applying GRO on GSO packets so they
too should be rejected. This allows GRO to be used in virtio-net
which may produce GSO packets directly but may still benefit
from GRO if the other end of it doesn't support GSO.

IDE: fix sparse signed-ness errors with host->host_busy
The host_busy field in struct ide_host defaults to a
signed-long, where most arch's test_and_set_bit_*

Change to using an unsigned long, which on ARM removes

Restart the request queue early for REQ_TYPE_PM_RESUME requests
(though there is only one resume request for the whole resume
sequence it stays in the queue until is fully completed and now
depends on kblockd for processing consequential resume states).

commit 54cc1428cfa619e16d75baae8cb041a2eff015f0 ("ide: remove
local_irq_set() macro") accidentally replaced local_save_flags()
by local_irq_set() in ide_probe_port() and __ide_wait_stat()
which resulted in LOCKDEP breakage.

mm: fix assertion
This assertion is incorrect for lockless pagecache. By definition if we
have an unpinned page that we are trying to take a speculative reference
to, it may become the tail of a compound page at any time (if it is
freed, then reallocated as a compound page).
It was still a valid assertion for the vmscan.c LRU isolation case, but
it doesn't seem incredibly helpful... if somebody wants it, they can
put it back directly where it applies in the vmscan code.
