From 153c7740c54b3c90129dbd3d6153ac1303c4d605 Mon Sep 17 00:00:00 2001
From: Lasse Collin <lasse.collin@tukaani.org>
Date: Tue, 12 Jan 2010 16:18:14 +0200
Subject: Add IRIX-specific code to tuklib_physmem and tuklib_cpucores.

This is untested but it will get tested soon and, if needed,
fixed before 5.0.0.

Thanks to Stuart Shelton.
