Subject: [PATCH v2 04/10] MIPS: SGI-IP27: do xtalk scanning later
Date: Tue, 19 Feb 2019 16:57:18 +0100	[thread overview]
Message-ID: <20190219155728.19163-5-tbogendoerfer@suse.de> (raw)
In-Reply-To: <20190219155728.19163-1-tbogendoerfer@suse.de>

Move xtalk scanning to a later boot stage to be able using things like
kmalloc and friends.
