percpu: reorder macros in percpu header files
* In include/asm-generic/percpu.h, collect {raw|_this}_cpu_generic*() macros into one place. They were dispersed through {raw|this}_cpu_*_N() definitions and the visiual inconsistency was making following the code unnecessarily difficult. * In include/linux/percpu-defs.h, move __verify_pcpu_ptr() later in the file so that it's right above accessor definitions where it's actually used. This is pure reorganization. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Christoph Lameter <cl@linux.com>
