[PATCH v2 17/25] include: <asm-generic/atomic.h>: remove stub IRQ save/restore

[Ahmad Fatoum <a.fatoum@xxxxxxxxxxxxxx>]

For an architecture to use <asm-generic/atomic.h>, it must define
local_irq_save() and local_irq_restore(). Instead of having every
platform define duplicate their stub definition, just drop them
altogether, so <asm-generic/atomic.h> can be used freestanding.
