From 80b9ece1339374444f08da46fa2383019fcf4374 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 30 Jun 2017 20:09:30 +0300 Subject: [PATCH] x86/io: Define IO accessors by preprocessor As a preparatory to use generic IO accessor helpers we need to define architecture dependent functions via preprocessor to let world know we have them.
