dst_cache_ctrl affects bits 3, 1 and 0 of AWCACHE but it is a 3-bit
field in the Channel Control Register (see Table 3-21 of the DMA-330
Technical Reference Manual) and should be programmed as such.

Bootup with lockdep enabled has been broken on v7 since b46c0f74657d
("ARM: 7321/1: cache-v7: Disable preemption when reading CCSIDR").
This is because v7_setup (which is called very early during boot) calls
v7_flush_dcache_all, and the save_and_disable_irqs added by that patch
ends up attempting to call into lockdep C code (trace_hardirqs_off())
when we are in no position to execute it (no stack, MMU off).
Fix this by using a notrace variant of save_and_disable_irqs. The code
already uses the notrace variant of restore_irqs.

It turns out that many compilers don't show section warnings on ARM
currently because handling for ARM_CALL relocs are missing from
modpost.c.
Based on commit c2e26114 ([ARM] 3205/1: Handle new EABI relocations when
loading kernel modules) it seems that R_ARM_PC24, R_ARM_CALL and
R_ARM_JUMP24 can be handled the same way.
Note that at least Debian libc6-dev is missing defines for both
R_ARM_CALL and R_ARM_JUMP24 in /usr/include/elf.h. So for now
we need to define them in modpost.c if not defined.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
One small bug fix from Axel plus a fix for a build failure in unrealistic
but commonly built configs which for some reason manage to survive for
an awfully long time in -next without any reports.
* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator:
regulator: Fix getting voltage in max8649_enable_time()
regulator: Fix mc13xxx regulator modular build (again)

Since mc13xxx-regulator-core.c and the actual drivers can get built
into seperate modules, you have to export the DT support symbols
"mc13xxx_get_num_regulators_dt" and "mc13xxx_parse_regulators_dt"
otherwise the allmodconfig build fails on sparc64.
[Updated the subject; the same thing was previously reported and fixed
in -next but for some reason nobody noticed for some considerable time
after the issue was introduced -- broonie]

EEH may happen during a PCI driver probe. If the driver is trying to
access some register in a loop, the EEH code will try to print the
driver name. But the driver pointer in struct pci_dev is not set until
probe returns successfully.
Use a function to test if the device and the driver pointer is NULL
before accessing the driver's name.

This fixes a hang that was observed during live partition migration.
Since stop_topology_update must not be called from an interrupt
context, call it earlier in the migration process. The hang observed
can be seen below:

It appears that on the Chroma card, the class code of the root
complex is still wrong even on DD2 or later chips. This could
be a firmware issue, but that breaks resource allocation so let's
unconditionally fix it up.

MMC fixes for 3.3-rc4:
* 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
in that mode, leading to lower-speed cards failing to mount.
* A lockdep warning introduced in 3.3-rc1 is fixed.
* Various other small driver fixes, most notably for a NULL dereference
when using highmem with dw_mmc.

Sometimes a software reset is needed. Then some registers are saved and
restored but the interrupt mask register is missing. It causes issues
with sdio devices whose interrupts are masked after reset.

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.

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

So we skip the calculation of timeout and use the max value to fix it.

When eSDHC module is enabled on P5020/P3041/P2041/P1010 with eSDHC
version 2.3, there is following errors:
mmc0: Timeout waiting for hardware interrupt.
mmc0: error -110 whilst initialising SD card
mmc0: Unexpected interrupt 0x02000000.
mmc0: Timeout waiting for hardware interrupt.
mmc0: error -110 whilst initialising SD card
mmc0: Unexpected interrupt 0x02000000.
It is because eSDHC controller has different bit setting for PROCTL
register at 0x28 comparing SD specification.
This patch sets DMAS bits correctly for byte operation and does not
change the default value of other field of PROCTL register.
For other FSL chips, such as MPC8536/P2020, PROCTL[DMAS]
bits are reserved and even if they are set to wrong bits, it will not
take effective.

When the initial domain starts, it prints (depending on the
amount of CPUs) a slew of
XENBUS: Unable to read cpu state
XENBUS: Unable to read cpu state
XENBUS: Unable to read cpu state
XENBUS: Unable to read cpu state
which provide no useful information - as the error is a valid
issue - but not on the initial domain. The reason is that the
XenStore is not accessible at that time (it is after all the
first guest) so the CPU hotplug watch cannot parse "availability/cpu"
attribute.

Merged back the fix for Acer Aspire 6935 with ALC889 codec.
The fix commit was based on 3.2 kernel so that it can be applied to
stable kernel cleanly.

Since 3.2 kernel, the driver starts trying to assign the multi-io DACs
before the speaker, thus it assigns DAC2/3 for multi-io and DAC4 for
the speaker for a standard laptop setup like a HP, a speaker, a mic-in
and a line-in. However, on Acer Aspire 6935, it seems that the
speaker pin 0x14 must be connected with either DAC1 or 2; otherwise it
results in silence by some reason, although the codec itself allows
the routing to DAC3/4.
As a workaround, the connection list of each pin is reduced to be
mapped to either only DAC1/2 or DAC3/4, so that the compatible
assignment as in kernel 3.1 is achieved.

VT1705 codec has two ADCs where the secondary ADC has no MUX but only
a fixed connection to the mic pin. This confused the driver and it
tries always overriding the input-source selection by assumption of
the existing MUX for the secondary ADC, resulted in resetting the
input-source at each time PM (including power-saving) occurs.
The fix is simply to check the existence of MUX for secondary ADCs in
the initialization code.

The new HP laptops turns off the mute LED with VREF50 or VREF80, but
not in HIZ unlike the previous models. Since VREF50 (also 80) works
with the previous models, let's use VREF50 for all.

standard_receive3 will check the validity of the response from the
server (via checkSMB). It'll pass the result of that check to handle_mid
which will dequeue it and mark it with a status of
MID_RESPONSE_MALFORMED if checkSMB returned an error. At that point,
standard_receive3 will also return an error, which will make the
demultiplex thread skip doing the callback for the mid.
This is wrong -- if we were able to identify the request and the
response is marked malformed, then we want the demultiplex thread to do
the callback. Fix this by making standard_receive3 return 0 in this
situation.

Currently, it's always set to 0 (no oplock requested).
