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.

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.

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.

Per ./Documentation/CodingStyle, goto statements are acceptable for the
centralized exiting of functions when there are multiple exit points which
share common work such as cleanup. When no common work is required for
multiple exit points, the function should just return at these exit points
instead of doing an unnecessary jump to a centralized return. This patch
cleans up the inappropriate use of goto statements, and removes unnecessary
variables (or move to a smaller scope) where possible as a result of the
cleanups.
