Re: Fw: [PATCH] Remove powerpc specific parts of 3c509 driver

The rest of this patch might indeed be correct, but the above comment 
bothers me. The "ns" versions of routines are supposed to be
non-byte-swapped versions of the insl/outsl routines (which would
byte-swap on big-endian archs such as powerpc.)

If it were true that in/outsw and in/outsl were actually used to
transfer arrays of 16-bit data items or 32-bit data items to/from an
I/O device, I would agree with you, but they aren't.  They are
universally used to transfer arrays of bytes, with the optimization of
doing so 2 or 4 bytes at a time.  That is why in/outsw and in/outsl
don't (and shouldn't) do byte swapping.
