[PATCH] fbdev: Shift pixel value before entering loop in cfbimageblit
In slow imageblit, the pixel value is shifted by a certain amount (dependent on the bpp and endianness) for each iteration. This is inefficient. Better do the shifting once before going into the loop. Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
