From caae6c961107c4c55731a86572f9a1f53837636b Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Sun, 13 Jul 2014 22:29:02 +0200 Subject: [PATCH] PPC: Mac: Move tbfreq into local variable We already expose the real CPU's tb frequency to the guest via fw_cfg. Soon we will need to also expose it to the MacIO, so let's move it to a variable that we can leverage every time we need the frequency.
