Add the option "mode_option". This is one step toward changing all fb drivers to have common "mode_option" parameter. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Cc: "Antonino A.

2007-10-16pm3fb: header file reductionKrzysztof Helt
This patch removes constants named AAA_DISABLE with value 0. They are redudant and misleading ( a |= AAA_DISABLE does nothing and usually should be a &= ~AAA_ENABLE).

2007-05-11pm3fb: Preliminary 2.4 to 2.6 portKrzysztof Helt
This is a basic port from 2.4 kernel to 2.6. Acceleration is lost and big endian support probably too. The driver works in 8, 16 and 32 bit mode.

2006-07-10[PATCH] vt: Remove VT-specific declarations and definitions from tty.hJon Smirl
MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h allows all of the framebuffer and VT console drivers to remove their dependency on tty.h.

2006-03-25[PATCH] Remove MODULE_PARMRusty Russell
MODULE_PARM was actually breaking: recent gcc version optimize them out as unused. It's time to replace the last users, which are generally in the most unloved drivers anyway.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
