ARM: entry: no need to increase preempt count for IRQ handlers irq_enter() and irq_exit() already take care of the preempt_count handling for interrupts, which increment and decrement the hardirq bits of the preempt count. So we can remove the preempt count handing in our IRQ entry/exit assembly, like x86 did some 9 years ago. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
