This patch should be split into one patch per subsystem or driver.
E.g. one patch for the iwlwifi driver, another patch for the mm
subsystem, one patch for the rwlock primitive, one patch for the
spinlock primitive, etc.

The tools/include/linux/compiler_types.h change probably should be
left out because it is user space code instead of kernel code and
the rest of the series applies to kernel code only.

Thanks,

Bart.
