I'm quite sure it is because of this changeset:

C Some 'overdrive' boards, such as those from Powerleap don't have
C the L2 cache enabled, and the BIOS doesn't know about it, so we
C introduce a boot option to 'force' it on.
Dave forgot to include system.h in his revised intel.c, so here is a
quick patch for it.

With this patch the kernel compiles cleanly.
