From 809aa5048fb7e7fd3bf0aa1fb169c42db0f63b08 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Wed, 9 May 2007 02:33:29 -0700 Subject: mca: fix bus matching There's a bug in the MCA bus matching algorithm in that it promotes from signed short to int before comparing with the actual id and does sign extension on anything > 0x7fff (which means that pos ids > 0x7fff never get correctly matched).
