Subject: [PATCH] dmaengine: fsldma: Add 64-bit I/O accessors for powerpc64
Date: Fri, 21 Dec 2018 22:34:45 -0600	[thread overview]
Message-ID: <20181222043445.GA29462@home.buserror.net> (raw)

Otherwise 64-bit PPC builds fail with undefined references
to these accessors.

Is there any reason why ioreadXXbe() etc can't be used on PPC as well?
