Currently, gpio_keys.c assumes the GPIOs to be already properly configured;
this patch changes gpio-keys to perform explicit calls to gpio_request() and
gpio_configure_input().

This matches the behaviour of leds-gpio.

Many mouse drivers are often compiled (e.g. in Linux distributions) into the
kernel at the same time just to make sure that at least one driver will suceed
in find it's mouse device. Nevertheless, only the inport and logitech busmouse
mouse drivers report with KERN_ERR log level if the mouse wasn't found. They
should use KERN_INFO instead, because it's not an error if the mouse isn't
attached at all.

Patch 49dce689 changed the sysfs data

It is not safe to to place struct pernet_operations in a special section.
We need struct pernet_operations to last until we call unregister_pernet_subsys.
Which doesn't happen until module unload.

So marking struct pernet_operations is a disaster for modules in two ways.
- We discard it before we call the exit method it points to.
- Because I keep struct pernet_operations on a linked list discarding
  it for compiled in code removes elements in the middle of a linked
  list and does horrible things for linked insert.

So this looks safe assuming __exit_refok is not discarded
for modules.

[PATCH] De-constify sched.h

This reverts commit a8972ccf ("sched:
constify sched.h")

 1) Patch doesn't change any code here, so gcc is already smart enough
    to "feel" constness in such simple functions.
 2) There is no such thing as const task_struct.  Anyone who think
    otherwise deserves compiler warning.
