This patch fixes the hardware cursor on mach64 when font width is not a multiple of 8 pixels. If you load such a font, the cursor is expanded to the next 8-byte boundary and a part of the next character after the cursor is not visible. For example, when you load a font with 12-pixel width, the cursor width is 16 pixels and when the cursor is displayed, 4 pixels of the next character are not visible. The reason is this: atyfb_cursor is called with proper parameters to load an image that is 12-pixel wide. However, the number is aligned on the next 8-pixel boundary on the line "unsigned int width = (cursor->image.width + 7) >> 3;" and the whole function acts as it is was loading a 16-pixel image. This patch fixes it so that the value written to the framebuffer is padded with 0xaaaa (the transparent pattern) when the image size it not a multiple of 8 pixels. The transparent pattern causes that the cursor will not interfere with the next character.
