[PATCH, RFC 14/22] oprofile: always enable IRQ_WORK

[Arnd Bergmann]

oprofile fails to build if CONFIG_IRQ_WORK is not already enabled,
because of the dependency on the RING_BUFFER code that now uses
the irq work library.

kernel/built-in.o: In function `ring_buffer_unlock_commit':
:(.text+0x5b8f0): undefined reference to `irq_work_queue'
kernel/built-in.o: In function `ring_buffer_write':
:(.text+0x5bd10): undefined reference to `irq_work_queue'
