[PATCH] fix a Sparse warning in the arch/x86/kernel/irq_work.c file

[Shailaja Neelam]

I am a high school student trying to become familiar with the
opensource process and linux kernel. This is my first submission to
the ITC mailing list.

My patch is for the file arch/x86/kernel/irq_work.c in the vesion
linux-3.10 kernel. When I ran the kernel with Sparse, the error read:
arch/x86/kernel/irq_work.c:21:
6: warning: symbol 'arch_irq_work_raise'
was not declared. Should it be static?

To fix this (rather than add static) I declared the symbol in the
header file linux/irq_work.h. Afterwards, my error did not show up
when I ran the kernel with Sparse again. I also ran the command "make
menuconfig" to change the kernel version so that I could assure the
correct kernel was running when I tested it, and it was. Then I test
built the kernel. It built and rebooted correctly.
