79. By Alexander Sack

* debian/patches/series,
  debian/patches/165_fedora_xserver-1.5.0-xaa-option-inversion.patch:
  - Turn on patch included in previous commit - obviously accidentially
    forgotten.
  - Now that its really enabled, make it apply to 1.4.1 code base
    accordingly. (LP: #182038)

78. By Bryce Harrington

* debian/patches/165_fedora_xserver-1.5.0-xaa-option-inversion.patch:
  - Turn XAA Offscreen Pixmaps off by default, and use
    XaaOffscreenPixmaps "true" to turn them on. This setting was an
    early pre-EXA HW optimization attempt that didn't pan out; upstream is
    deprecating XAA in favor of EXA generally, and for situations where
    XAA is still in use recommends NOT using this optimization hack, since
    they found it often just made performance worse, and sometimes created
    visualization bugs. People wishing to gain added performance should be
    experimenting with EXA anyway, not this setting. (closes LP: #182038)

77. By Timo Aaltonen

  - 163_fix_untrusted_access.diff:
