Subject: [PATCH 1/3] x86: make printk_address available on X86_32
Date: Mon, 21 Jan 2008 14:57:55 -0800 [thread overview]
Message-ID: <1200956275.16972.39.camel@brick> (raw)
Small fomatting fixes to 64-bit as well, trailing whitespace
and extra semicolon, also move the ifdefs for CONFIG_KALLSYMS
into the function itself.
