* remotes/kraxel/tags/pull-vga-20141002-1:
  vga: Add endian to vmstate
  vga: Make fb endian a common state variable
  vga: Rename vga_template.h to vga-helpers.h
  vga: Remove some "should be done in BIOS" comments
  cirrus: Remove non-32bpp cursor drawing
  vga: Simplify vga_draw_blank() a bit
  vga: Remove rgb_to_pixel indirection
  vga: Separate LE and BE conversion functions
  vga: Remove remainder of old conversion cruft
  vga: Start cutting out non-32bpp conversion support
