And the driver is already ppc-specific; it uses in/out_be32.
True, but its hidden behind the gfar_read/write accessors.
Your change is a bit more blatant.
Well, Segher doesn't want me to use iobarrier (because it's not I/O).
Andy doesn't want me to use wmb() (because it's sync).
You should use wmb(), but unfortunately too strong
semantics are required for that (ordering wrt I/O)
so it's a full sync on PowerPC. I don't believe
a priori that that would be notably slower, but if
actually is, you could use eieio() I suppose since
you say the driver is powerpc specific -- but please
put a comment in the source code then saying why you
don't use wmb() there.
