* missing braces in !readl(...) & ... * trivial endianness annotations * in olympic_arb_cmd() the loop collecting fragments of packet is b0rken on big-endian - we have (next_ptr && (buf_ptr=olympic_priv->olympic_lap + ntohs(next_ptr))) as condition and it should have swab16(), not ntohs() - it's host-endian byteswapped, not big-endian. So if we get more than one fragment on big-endian host, we get screwed. This ntohs() got missed back when the rest of those had been switched to swab16() in 2.4.0-test2-pre1 - at a guess, nobody had hit fragmented packets during the testing of PPC fixes. PS: Ken Aaker cc'd on assumption that he is the same guy who'd done the original set of PPC fixes in olympic Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jeff Garzik <jeff@garzik.org>
