This patch series implements clock deregistration in the common clock

Add helper functions for the of_clk_providers list locking and
an unlocked variant of of_clk_get_from_provider().
These functions are intended to be used in the clkdev to avoid
race condition in the device tree based clock look up in clk_get().
Signed-off-by: Sylwester Nawrocki
The clock core code is going to be modified so clk_get() takes
reference on the clock provider module. Until the potential circular
reference issue is properly addressed, we pass NULL as the first
argument to clk_register(), in order to disallow sub-devices taking
a reference on the ISP module
There is currently a race condition in the device tree part of clk_get()
function, since the pointer returned from of_clk_get_by_name() may become
invalid before __clk_get() call. E.g. due to the clock provider driver
remove() callback being called in between of_clk_get_by_name() and
__clk_get().
This patch adds common __clk_get(), __clk_put() clkdev helpers that
replace their platform specific counterparts when the common clock
API is used.
The owner module pointer field is added to struct clk so a reference
to the clock supplier module can be taken by the clock consumers.
The owner
clk_unregister() is currently not implemented and it is required when
a clock provider module needs to be unloaded.
Normally the clock supplier module is prevented to be unloaded by
taking reference on the module in clk_get().
For cases when the clock supplier module deinitializes despite the

Using Rabin Vincent's ARM uprobes patches as a base, enable uprobes
support on ARM.
Caveats:
- Thumb is not supported
- XOL abort/trap handling is not implemented

I think kexec_add_buffer is guaranteed to be called before allocating
control pages, why not updating image-control_page after each time

This patch series adds basic uprobes support to ARM. It is based on patches
developed earlier by Rabin Vincent. That approach of adding hooks into
the kprobes instruction parsing code was not well received.

Added detection for newer Elantech touchpads, so that kernel doesn't
fall-back to default PS/2 driver. Supports touchpads released after
~August 2013. Fixes bug:
