PERFMON isn't operational on amd64

[pluknet]

Hi.

What is a status of "options PERFMON" on amd64?
AFAIK PERFMON opt. was inherited from i386 port and never worked.
Does it make sense to wipe out perfmon part on amd64?

buildkernel with PERFMON on results in error:
/usr/src/sys/amd64/amd64/machdep.c:124:29: error: machine/perfmon.h:
No such file or directory
mkdep: compile failed
*** Error code 1

Looking at cvs I see amd64/include/perfmon.h was never here.
