Subject: [Qemu-devel] [PATCH for-2.13 04/10] spapr: Set compatibility mode before the rest of spapr_cpu_reset()
Date: Tue, 17 Apr 2018 17:17:16 +1000 [thread overview]
Message-ID: <20180417071722.9399-5-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20180417071722.9399-1-david@gibson.dropbear.id.au>
Although the order doesn't really matter at the moment, it's possible
other initializastions could depend on the compatiblity mode, so make sure
we set it first in spapr_cpu_reset().
While we're at it drop the test against first_cpu. Setting the compat mode
to the value it already has is redundant, but harmless, so we might as well
make a small simplification to the code.
