Subject: riscv64: initialize stathz, profhz like other platforms do
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=5306634dc593786510f2860182776be737cd5cee;p=openbsd

riscv64: initialize stathz, profhz like other platforms do

Don't hardcode 100 and 1000.  Use hz(9) for stathz, compute profhz
using stathz, just like most other platforms.
