Subject: ARM: 8371/1: always select IRQ_WORK on SMP
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0361748f3b4a1cd73657a0a44fc3bc71ea30e8eb;p=linux-beck.git

ARM: 8371/1: always select IRQ_WORK on SMP

Any SMP kernel now requires the irq_work code after
generic_smp_call_function_single_interrupt() started using it,
or we get:

kernel/built-in.o: In function `flush_smp_call_function_queue':
:(.text+0x4dc3a): undefined reference to `irq_work_run'

Fixes: 478850160636c4f ("irq_work: Implement remote queueing")
