13d261932b sound fixes for 3.3-rc4
Basically all small fixes suited as rc4: a few HD-audio regression fixes,
 a stable fix for an old Dell laptop with intel8x0, and a simple fix for
 ASoC fsi.

The reporter states that audio is inaudible by default without muting
'External Amplifier'. Add a quirk to handle his SSID so that changing
the control is not necessary.

ca81a62198 Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
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.

778a785f02 powerpc/pseries/eeh: Fix crash when error happens during device probe
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:

5ba85d95ca mmc: sh_mmcif: fix late delayed work initialisation
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.

6e8201f57c mmc: core: add the capability for broken voltage
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.

This set of changes are fixing various section mismatch warnings which
look to be completely valid.  Primerily, those which are fixed are those

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

5b1cbac377 i387: make irq_fpu_usable() tests more robust
Some code - especially the crypto layer - wants to use the x86
FP/MMX/AVX register set in what may be interrupt (typically softirq)
context.

That *can* be ok, but the tests for when it was ok were somewhat
suspect.  We cannot touch the thread-specific status bits either, so
we'd better check that we're not going to try to save FP state or
anything like that.

Now, it may be that the TS bit is always cleared *before* we set the
USEDFPU bit (and only set when we had already cleared the USEDFP
before), so the TS bit test may actually have been sufficient, but it
certainly was not obviously so.

So this explicitly verifies that we will not touch the TS_USEDFPU bit,
and adds a few related sanity-checks.  Because it seems that somehow
AES-NI is corrupting user FP state.  The cause is not clear, and this
patch doesn't fix it, but while debugging it I really wanted the code to
be more obviously correct and robust.

ea51ade939 fec: fix PHY name to match fixed MDIO bus name
Commit "391420f7: fec: use an unique MDIO bus name" first modified
the MDIO bus name to include the platform name, then in commit
"a7ed07d5: net: fec: correct phy_name buffer length when init phy_name"
the PHY name formatting was fixed in the case the PHY matches a PHY
driver.

The FEC driver however, also handles the case where we want to attach
to the fixed MDIO bus name, which was previously named "0", and now
"fixed-0". Change the PHY formatting logic to account for that.

c56e9e2ae7 bcm63xx-enet: fix PHY name to match MDIO bus name
Commit 3e617506: bcm63xx_enet: use an unique MDIO bus name introduced
a regression in the PHY connection logic, since the PHY name was formatted
to expect the bus name to be "0" or "1", whereas it is now "bcm63xx-enet-0"
or "bcm63xx-enet-1".

a19c5d6841 cpmac: fix PHY name to match MDIO bus name
Commit d1733f07: cpmac: use an unique MDIO bus name changed the MDIO bus
name from "1" to "cpmac-1", this breaks the PHY connection logic because
the PHY name still uses the old bus names "0" and "1", fix that to
always use the mdio bus id instead.
