Replace various atomic_ts used as flags in struct se_cmd with a single
transport_state bitmap that requires t_state_lock to be held for modifications.
In the target core that assumption generally is true, but some recently added
code in the SRP target had to grow new lock calls. I can't say I like the way
how it messes with the command state directly, but let's leave that for later.
(Re-add missing ib_srpt.c changes that nab dropped..)

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
These are the bug fixes that have accumulated since 3.3-rc3 in arm-soc.
The majority of them are regression fixes for stuff that broke during
the merge 3.3 window.
The notable ones are:
* The at91 ata drivers both broke because of an earlier cleanup patch that
some other patches were based on. Jean-Christophe decided to remove
the legacy at91_ide driver and fix the new-style at91-pata driver while
keeping the cleanup patch. I almost rejected the patches for being too
late and too big but in the end decided to accept them because they
fix a regression.
* A patch fixing build breakage from the sysdev-to-device conversion
colliding with other changes touches a number of mach-s3c files.
* b0654037 "ARM: orion: Fix Orion5x GPIO regression from MPP cleanup"
is a mechanical change that unfortunately touches a lot of lines
that should up in the diffstat.

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Here are a few more fixes for powerpc. Some are regressions, the rest
is simple/obvious/nasty enough that I deemed it good to go now.
Here's also step one of deprecating legacy iSeries support: we are
removing it from the main defconfig.
Nobody seems to be using it anymore and the code is nasty to maintain,
(involves horrible hacks in various low level areas of the kernel) so we
plan to actually rip it out at some point. For now let's just avoid
building it by default. Stephen will proceed to do the actual removal
later (probably 3.4 or 3.5).

There a two different irq variables ks->irq and netdev->irq.
Only ks->irq is set on probe, so disabling irq in ks_start_xmit fails.
This patches remove ks->irq from private data and use only netdev->irq.

This patch moves the MAC HW initialization and
the HW feature verification from the open to the probe
function as D. Miller suggested.
So the patch actually reorganizes and tidies-up some parts of
the driver and indeed fixes some problem when tune its HW features.
These can be overwritten by looking at the HW cap register at
run-time and that generated problems.

When adding new unicast steer entry, before moving qp to state ready,
actually before calling mlx4_RST2INIT_QP_wrapper(), there were added

Currently registers with a value of 0 are ignored when initializing the register
defaults from raw defaults. This worked in the past, because registers without a
explicit default were assumed to have a default value of 0. This was changed in
commit b03622a8 ("regmap: Ensure rbtree syncs registers set to zero properly").
As a result registers, which have a raw default value of 0 are now assumed to
have no default. This again can result in unnecessary writes when syncing the
cache. It will also result in unnecessary reads for e.g. the first update
operation. In the case where readback is not possible this will even let the
update operation fail, if the register has not been written to before.
So this patch removes the check. Instead it adds a check to ignore raw defaults
for registers which are volatile, since those registers are not cached.

* The most visible fix here is against a regression introduced in 3.3-rc1
that ran cards in Ultra High Speed mode even when they failed to initialize

Jean Delvare reported bonding on top of 3c59x adapters was not detecting
network cable removal fast enough.
3c59x indeed uses a 60 seconds timer to check link status if carrier is
on, and 5 seconds if carrier is off.
This patch reduces timer period to 5 seconds if device is a bonding

If the driver is loaded with a card in the slot, mmc_add_host() will
schedule an immediate card-detection work, which will start IO and wait
for command completion. Usually the kernel first returns to the sh_mmcif
probe function, lets it finish and only then schedules the rescan work.
But sometimes, expecially under heavy system load, the work will be
scheduled immediately before returning to the probe method. In this case
it is important for the driver to be fully prepared for IO. For sh_mmcif
this means, that also the timeout work has to be initialised before
calling mmc_add_host(). It is also better to prepare interrupts
beforehand. Besides, since mmc_add_host() does card-detection itself,
there is no need to do it again immediately afterwards.

When DMA is in use and the card is ejected during IO, DMA transfers have to
be terminated, otherwise the dmaengine driver fails to operate properly,
when the card is re-inserted.

Found this issue during code review. Actually, there are two issues which
both compensate together in lucky case. In unlucky case the bus width
probing might not work as expected.

Modified the mmc_poweroff to resume before sending the poweroff
notification command. In sleep mode only AWAKE and RESET commands are
allowed, so before sending the poweroff notification command resume from
sleep mode and then send the notification command.
PowerOff Notify is tested on a Synopsis Designware Host Controller
(eMMC 4.5). The suspend to RAM and resume works fine.

There is an understood mismatch between the voltage the host controller is
set to and the voltage supplied to the card by a fixed voltage regulator.
Teaching the driver to accept the mismatch is overly complicated. Instead
just accept the regulator's voltage.
This patch adds MMC_CAP2_BROKEN_VOLTAGE.
If the voltage didn't satisfy between min_uV and max_uV, try to change
the voltage in core.c. When changing the voltage, maybe use
regulator_set_voltage().
In regulator_set_voltage(), check the below condition.
/* sanity check */
if (!rdev->desc->ops->set_voltage &&
!rdev->desc->ops->set_voltage_sel) {
ret = -EINVAL;
goto out;
}
If some board should use the fixed-regulator, always return -EINVAL.
Then, eMMC didn't initialize always.
So if use a fixed-regulator, we need to add the MMC_CAP2_BROKEN_VOLTAGE.

When accessing the card on some FSL platform boards (e.g p2020, p1010,
mpc8536), the following error is reported with the timeout value calculated:
mmc0: Got data interrupt 0x00000020 even though no data operation was
in progress.
mmc0: Got data interrupt 0x00000020 even though no data operation was
in progress.
So we skip the calculation of timeout and use the max value to fix it.

For some FSL ESDHC controllers (e.g. P2020E, Rev1.0), the SDHC can not

A UHS sdio card that fails initialization at 1.8v signaling is not in
UHS mode. We cannot use the speed in the the cis to reflect the bus
speed as this is the maxiumum value and will not reflect the fact
that the host is operating at a lower (non uhs) bus speed.

This set of changes are fixing various section mismatch warnings which
look to be completely valid. Primerily, those which are fixed are those
which can cause oopses by manipulation of driver binding via sysfs. For
example: calling code marked __init from driver probe __devinit
functions.
Some of these changes will be reworked at the next merge window when the
underlying reasons are sorted out. In the mean time, I think it's
important to have this fixed for correctness.
Also included in this set are fixes to various error messages in OMAP -
including making them gramatically correct, fixing a few spelling
errors, and more importantly, making them greppable by unwrapping them.
Tony Lindgren has acked all these patches, put them out for testing a
week ago, and I've tested them on the platforms I have.
