>Description:
I've compiled a kernel with pmc support and discovered that it does not
work, even if my CPU (Pentium II) has pmc support. (pmc -h prints 
pmc: PMC counters are not supported for your CPU (0x0) .)

The cause seems to be this commit to sys/arch/i386/i386/pmc.c :

----------------------------
revision 1.5
date: 2002/10/05 05:55:46;  author: gmcgarry;  state: Exp;  lines: +4 -2
branches:  1.5.2;
At least make it compile even though it doesn't make sense.
----------------------------

The log mesage is correct.
>How-To-Repeat:
pmc -h on a kernel with options         PERFCTRS
>Fix:
Upgrade sys/arch/i386/i386/pmc.c to rev. 1.7
