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 b46c0f74
("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.

 * A lockdep warning introduced in 3.3-rc1 is fixed.

This updates the sha512 fix so that it doesn't cause excessive stack
usage on i386.  This is done by reverting to the original code, and
avoiding the W duplication by moving its initialisation into the loop.

As the underlying code is in fact the one that we have used for years,
I'm pushing this now instead of postponing to the next cycle.

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

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.

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.
