From f5a9951c94e7a285a3d00648e3d790a7f016bd11 Mon Sep 17 00:00:00 2001 From: James Simmons Date: Tue, 21 Jun 2005 17:16:58 -0700 Subject: [PATCH] fbdev: iomove removal Since no one is using the inbuf, outbuf of struct fb_pixmap I removed their use in the framebuffer console. The idea is instead move the pixmap functionality below the accelerated functions intead of on top as the way it is now. If there is no objection please apply. This is against Linus latestr GIT tree.
