The bisection implemented in unwind_find_origin() stopped to early. If
there is only a single entry left to check the original code just took
the end point as origin which might be wrong.
This was introduced in commit de66a97901 ("ARM: 7187/1: fix unwinding
for XIP kernels").

Commit 10299e2e4e (ARM: RX-51:
Enable isp1704 power on/off) added power management for isp1704.
However, the transceiver should be powered on by default,
otherwise USB doesn't work at all for networking during
boot.
All kernels after v3.0 are affected.

Since commit 6571534 (plat-mxc: iomux-v3.h: implicitly enable

babbage board stopped working because it's pulled up by mistake.
The patch removes the pull-up setting from the pad configuration for
that gpio to make the power button back to work.

The SMDK board uses LT3591 as backlight LED driver of LTE480WV LCD.
According to the LT3591 datasheet, the switching frequency should
be 1MHz. So, PWM period is calculated by following formula:
PWM period = 1/switching frequency
= 1/1MHz
= 1000ns
Thus, the PWM backlight period should be 1000ns.

In the unlikely case that a platform registers a PMU platform_device
when running on a CPU that is unsupported by perf, we will encounter a
NULL dereference when trying to assign the platform_device to the
cpu_pmu structure.
This patch checks that the CPU is supported by perf before assigning
the platform_device.

The linker places the unwind tables in readonly sections. So when using
an XIP kernel these are located in ROM and cannot be modified.
For that reason the current approach to convert the relative offsets in
the unwind index to absolute addresses early in the boot process doesn't
work with XIP.
The offsets in the unwind index section are signed 31 bit numbers and
the structs are sorted by this offset. So it first has offsets between
0x40000000 and 0x7fffffff (i.e. the negative offsets) and then offsets
between 0x00000000 and 0x3fffffff. When seperating these two blocks the
numbers are sorted even when interpreting the offsets as unsigned longs.
So determine the first non-negative entry once and track that using the
new origin pointer. The actual bisection can then use a plain unsigned
long comparison. The only thing that makes the new bisection more
complicated is that the offsets are relative to their position in the
index section, so the key to search needs to be adapted accordingly in
each step.
Moreover several consts are added to catch future writes and rename the
member "addr" of struct unwind_idx to "addr_offset" to better match the
new semantic. (This has the additional benefit of breaking eventual
users at compile time to make them aware of the change.)
In my tests the new algorithm was a tad faster than the original and has
the additional upside of not needing the initial conversion and so saves
some boot time and it's possible to unwind even earlier.

Commit 1b9f95f8ad (ARM: prepare for removal of a bunch of <mach/memory.h>
files) introduced CONFIG_PHYS_OFFSET but the Kconfig hex prompt did not
provide a default value.
This has the undesired side effect of breaking a reportedly used
trick for updating defconfigs on the fly for routine buildtesting
across all arch and all platforms, i.e.
cp /path/to/somedefconfig .config ; yes "" | make oldconfig
because the config system will endlessly loop until a valid address is
provided.
However we can't just pick a random default value since it is likely to
be wrong for the majority of the boards as the right answer for this
option is quite varied. So the fact that the config system insists on
having a proper value be entered is actually a good thing.
It turns out that only at91x40_defconfig has this problem because it has
CONFIG_MMU=n. However, in the !MMU case, there is already a CONFIG_DRAM_BASE
value that can be used here. So let's use that as a default in that case
and suppress the redundant CONFIG_PHYS_OFFSET prompt.
Eventually the DRAM_BASE config option could simply be replaced by
PHYS_OFFSET directly, but that's a larger change better suited for later.

On OMAP-L138 platform, EDMA event queue 0 should be used for audio
transfers so that they are not starved by video data moving on event queue 1.
Commit 48519f0ae0 (ASoC: davinci: let platform
data define edma queue numbers) had a side-effect of changing this behavior
by making the driver actually honor the platform data passed.
Fix this now by passing event queue 0 as the queue to be used for audio
transfers.
