Subject: [PATCH 2/3] powerpc/powernv: Use __raw_[rm_]writeq_be() in pci-ioda.c
Date: Mon, 14 May 2018 22:50:32 +1000	[thread overview]
Message-ID: <20180514125033.12000-2-mpe@ellerman.id.au> (raw)
In-Reply-To: <20180514125033.12000-1-mpe@ellerman.id.au>

This allows us to squash some sparse warnings and also avoids having
to do explicity endian conversions in the code.
