ppc: make PPC_BOOK3S_64 select IRQ_WORK

Fix breakage which will be exposed by the patch "kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT". arch/powerpc/kernel/mce.c, compiled in for PPC_BOOK3S_64, calls functions only built when IRQ_WORK, so select it. Fixes the following build error: arch/powerpc/kernel/built-in.o: In function `.machine_check_queue_event': (.text+0x11260): undefined reference to `.irq_work_queue' Signed-off-by: Josh Triplett <[email protected]> Reported-by: Stephen Rothwell <[email protected]> Acked-by: Benjamin Herrenschmidt <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
