From 57594742a2b545f8f114cda34f15650be8ae976d Mon Sep 17 00:00:00 2001 From: Akinobu Mita Date: Sun, 19 Jul 2009 00:11:06 +0900 Subject: x86: Introduce set_desc_base() and set_desc_limit() Rename set_base()/set_limit to set_desc_base()/set_desc_limit() and rewrite them in C. These are naturally introduced by the idea of get_desc_base()/get_desc_limit(). The conversion actually found the bug in apm_32.c: bad_bios_desc is written at run-time, but it is defined const variable.
