[PATCH] Update cyblafb driver
This is a major update to the cyblafb framebuffer driver. Most of the stuff has been tested in the mm tree. Main advantages: ============ - vxres > xres support - ywrap and xpan support - much faster for almost all modes (e.g. 1280x1024-16bpp draws more than 41 full screens of text instead of about 25 full screens of text per second on authors Epia 5000) - module init/exit code fixed - bugs triggered by console rotation fixed - lots of minor improvements - startup modes suitable for high performance scrolling in all directions This diff also contains a lot of white space fixes. No side effects are possible, only one single graphics core is affected. Signed-off-by: Knut Petersen <Knut_Petersen@t-online.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
