Does tprof work on amd64? When I tried it a couple of days ago, tprof
complained about missing /dev/tprof. I recompiled the kernel with

	options GPROF
	pseudo-device tprof

then tried creating the device with MAKEDEV. It didn't know about
tprof and I had to dig a major number in the code to create it manually.

With /dev/tproj available, the tool complained about unsupported cpu.
I'm on haswell notebook.

It'd be nice to mention /dev/tprof in the man page and list common
errors.
