Subject: [PATCH] Fix vgacon oops on 64-bit
Date: Mon, 30 Jan 2006 08:33:21 -0700 [thread overview]
Message-ID: <20060130083321.B3098@cox.net> (raw)
Although I'm not running a VGA card, I noticed this building
a working malta 32-bit defconfig (vgacon enabled) for 64-bit.
Without it, the vgacon probe will access unmapped space when
looking to see if a vga card is present.
