From 7752572f18f98ee796e173334b088a1d621d2da4 Mon Sep 17 00:00:00 2001 From: Yanchuan Nian Date: Wed, 4 Sep 2013 09:25:24 +0800 Subject: [PATCH] x86/irq: Correct comment about i8259 initialization 0x30-0x3f have been used for ISA interrupts on i386 as well since 5 years ago, but old comments about i8259 initialization were still referring to the old i386 usage of this port range.
