irq_work: fix compile failure on MIPS from system.h split
Builds of the MIPS platform ip32_defconfig fails as of commit 0195c002 ("Merge tag 'split-asm_system_h ...") because MIPS xchg() macro uses BUILD_BUG_ON and it was moved in commit b81947c6 ("Disintegrate asm/system.h for MIPS"). The root cause is that the system.h split wasn't tested on a baseline with commit 6c03438e ("kernel.h: doesn't explicitly use bug.h, so don't include it.") Since this file uses BUG code in several other places besides the xchg call, simply make the inclusion explicit. Signed-off-by:Paul Gortmaker <paul.gortmaker@windriver.com> Acked-by:
