[RFC: 2.6 patch] include/linux/irq.h: #include <linux/smp.h>

[Adrian Bunk]

Jan's crosscompile page [1] shows, that one regression in 2.6.15-rc is 
that the v850 defconfig does no longer compile.

The compile error is:

<--  snip  -->

...
  CC      arch/v850/kernel/setup.o
In file included from /usr/src/ctest/rc/kernel/arch/v850/kernel/setup.c:17:
/usr/src/ctest/rc/kernel/include/linux/irq.h:13:43: asm/smp.h: No such file or directory
make[2]: *** [arch/v850/kernel/setup.o] Error 1

<--  snip  -->


The #include <asm/smp.h> in irq.h was intruduced in 2.6.15-rc.

Since include/linux/irq.h needs code from asm/smp.h only in the 
CONFIG_SMP=y case and linux/smp.h #include's asm/smp.h only in the
CONFIG_SMP=y case, I'm suggesting this patch to #include <linux/smp.h>
in irq.h.

I've tested the compilation with both CONFIG_SMP=y and CONFIG_SMP=n
on i386.
