Currently, setting up the portmux is completely one-shot: Once a pin is
muxed, the portmux driver will complain loudly and refuse to do anything
if you try to set up the same pin again.

Sometimes, it may be necessary to change the configuration of a pin
after it has been set up initially. This patch adds a way to undo the
previous configuration, allowing the pin to be reconfigured.

The NGW100 board has jumper J15 (near the reset button) which
is unused.  This patch exports it through the GPIO sysfs support
(as /sys/class/gpio/gpio62/value) so that it's easily queried
by boot scripts or whatever might want to know if the jumper
has been installed (value = 0) or not (value = 1, "default").

This patch adds backtracing capability to oprofile profiling in kernel
and user mode on AVR32. This is done by going through the frames on the
stack and adding oprofile traces for all return addresses. The code
being profiled has to be compiled with frame pointers to make this work.

The mutex mmc_test_lock is initialized at every time mmc_test device
is probed. Probing another mmc_test device may break the mutex, if
the probe function is called while the mutex is locked.

This patch fixes it by statically initializing mmc_test_lock.
