The patch titled
Subject: irq_work: fix build failure when CONFIG_IRQ_WORK not defined
has been removed from the -mm tree. Its filename was
irq_work-fix-build-failure-when-config_irq_work-not-defined.patch
This patch was dropped because it was merged into mainline or a subsystem tree

From: Steven Rostedt <rostedt@xxxxxxxxxxx>
Subject: irq_work: fix build failure when CONFIG_IRQ_WORK not defined
When CONFIG_IRQ_WORK is not defined (difficult to do, as it also requires
CONFIG_PRINTK not to be defined), we get a build failure:
kernel/built-in.o: In function `flush_smp_call_function_queue':
kernel/smp.c:263: undefined reference to `irq_work_run'
kernel/smp.c:263: undefined reference to `irq_work_run'
Makefile:933: recipe for target 'vmlinux' failed
Simplest thing to do is to make irq_work_run() a nop when not set.
