From 94eaa79cecf98300974c99d935ff653c9418de21 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 19 Aug 2016 01:23:27 +0200 Subject: cpu: Add get_vendor callback The CPU udevice already has a few callbacks to retreive information about the currently running CPUs. This patch adds a new get_vendor() call that returns the vendor of the main CPUs.
