From b563e748a9fe1f08ff11ade92b0caa52d3ea1b47 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Added ifdefs so that this compiles when neither I586_CPU nor
 I586_CPU is defined, or SMP is defined.  It is silly to configure PERFMON
 when it can't work (it will be disabled at runtime), but I like to leave the
 PERFMON configuration alone when I temporarily disable support for modern
 CPUs to run regression tests.

Removed an unused #include.
