[PATCHv2 2/2] fbmem, drm/nouveau: kick firmware framebuffers as soon as possible

Currently vesafb/efifb/... is kicked when hardware driver is registering framebuffer. To do it hardware must be fully functional, so there's a short window between start of initialisation and framebuffer registration when two drivers touch the hardware. Unfortunately sometimes it breaks nouveau ini

[PATCHv2 1/2] fbdev: allow passing more than one aperture for handoff

It simplifies nouveau code by removal of detection which region to pass to kick vesafb/efifb. Signed-off-by: Marcin Slusarz Cc: Eric Anholt Cc: Ben Skeggs Cc: Thomas Hellstrom Cc: Dave Airlie Cc: Peter Jones Cc: Andrew Morton Cc: Benjamin Herrenschmidt --- v2 - rebase after drop of patch 1

[PATCH 1/3] fbmem: fix aperture overlapping check

fb_do_apertures_overlap is returning wrong value when one aperture is completely whithin the other. Add generic ranges_overlap macro (probably kernel.h candidate) and use it here. Signed-off-by: Marcin Slusarz Cc: Dave Airlie Cc: Peter Jones Cc: Andrew Morton --- drivers/video/fbmem.c | 24
