Subject: [PATCH 04/14] powerpc/64s/exception: machine check adjust RFI target
Date: Wed, 3 Jul 2019 17:54:34 +1000 [thread overview]
Message-ID: <20190703075444.19005-5-npiggin@gmail.com> (raw)
In-Reply-To: <20190703075444.19005-1-npiggin@gmail.com>
The host kernel delivery case for powernv does RFI_TO_USER_OR_KERNEL,
but should just use RFI_TO_KERNEL which makes it clear this is not a
user case.
This is not a bug because RFI_TO_USER_OR_KERNEL deals with kernel
returns just fine.
