Subject: [PATCH] libxc fix: fast trap id is only for x86 patch
Date: Wed, 02 Mar 2005 15:19:00 -0600 [thread overview]
Message-ID: <1109798340.6039.19.camel@thinkpad> (raw)
[-- Attachment #1: Type: text/plain, Size: 323 bytes --]
x86 ( 32bit) is the only architecture that uses Fast trap vector offset
( fast_trap_idx ). This makes sure that x86 is the only architecture to
use this variable.
