  To: Andrew Morton; +Cc: Linux Fbdev development list, linux-kernel

- This patch removes the unnecessary call to banshee_wait_idle() from
  tdfxfb_copyarea, imageblit and fillrect.  Removal of the sync will garner
  an additional ~20% in scrolling speed.

- Removes "inverse" which generates a compile warning if modular.
