From fafb7a97de73a917a875048801bd81cf64f79e4a Mon Sep 17 00:00:00 2001 From: Nobuhiro Iwamatsu Date: Tue, 24 Jun 2008 13:00:52 +0900 Subject: sh: Remove sh_pcic_io_xxx function from Solution Engine IO code sh_pcic_io_xxx function are very old. In linux-2.4, mrshpc_ss socket driver used this function. But there is not this driver to the present kernel. I deleted these cords and checked operation.
