From 3e6c6f630a5282df8f3393a59f10eb9c56536d23 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Tue, 16 Oct 2007 23:30:13 -0700 Subject: Delay creation of khcvd thread This changes hvc_init() to be called only when someone actually uses the hvc_console driver. Dave Jones complained when profiling bootup. hvc_console used to only be for Power aka pSeries: now lguest and Xen both want it built-in in case the kernel is a guest under one of those, even though usually it will be a native boot.
