Subject: [PATCH 01/11] irq_work: fix compile failure on MIPS from system.h split

From: Paul Gortmaker <[email-masked]>
Date: Sun, 1 Apr 2012 16:38:37 -0400

Builds of the MIPS platform ip32_defconfig fails as of
commit 0195c00244dc2e9f522475868fa278c473ba7339

    "Merge tag 'split-asm_system_h-for-linus-20120328' ..."

because MIPS xchg() macro uses BUILD_BUG_ON and it was moved
in commit b81947c646bfefdf98e2fde5d7d39cbbda8525d4

    "Disintegrate asm/system.h for MIPS"

The root cause is that the system.h split wasn't tested on
a baseline with commit 6c03438edeb5c359af35f060ea016ca65671c269

    "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.
