Subject: [PATCH] Save 2k text size in cpu-probe
Date: Mon, 3 Jul 2006 13:30:01 +0100 [thread overview]
Message-ID: <20060703123001.GA6625@networkno.de> (raw)
The appended patch drops the inline for decode_configs, this saves about
2k of text size. It also uses MIPS_CONF_AR instead of magic constants.
