Subject: [PATCH 4/9] x86/init: make ebda depend on PC subarch
Date: Fri, 19 Feb 2016 05:08:31 -0800 [thread overview]
Message-ID: <1455887316-9223-5-git-send-email-mcgrof@kernel.org> (raw)
In-Reply-To: <1455887316-9223-1-git-send-email-mcgrof@kernel.org>
This lets us remove its use of paravirt_enabled(). The
other subarchs are not needed here given that on 32-bit
there is a switch already that negates access to this
code on X86_SUBARCH_INTEL_MID, and X86_SUBARCH_CE4100.
Both lguest and Xen had paravirt_enabled so that
excludes them.
