* PRs 6923 and 6967:
* #include <linux/smp.h> should be sufficient, but there are some
* problems with #include hygiene in this area:
* i386, recent kernels: linux/smp.h needs linux/irqflags.h.
* s390, RHEL5.2: linux/irqflags.h needs asm/system.h (and
* linux/kernel.h, which asm/system.h includes).
*
* #include <linux/kernel.h> is probably redundant here, since
* everybody's <asm/system.h> seems to include it, but nobody
* seems to #include <asm/system.h> without <linux/kernel.h> first.
*
* <asm/system.h> includes <linux/irqflags.h> on most architectures,
* so we don't explicitly include it here. The exception is ia64,
* but <linux/smp.h> alone seemed to be sufficient for ia64 here.
