[PATCH] cmap annotations
fb_set_cmap() and fb_copy_cmap() split into kernel and userland versions.
fb_cmap, fb_image and fb_cursor split and annotated.
fixed bug in sbuslib.c that used to call "userland" version of fb_set_cmap()
when kernel one was need (RGB data was already copied into kernel space).
