6ca03b9161 xf86: fix flush input to work with Linux evdev devices.
So when we VT switch back and attempt to flush the input devices,
we don't succeed because evdev won't return part of an event,
since we were only asking for 4 bytes, we'd only get -EINVAL back.

This could later cause events to be flushed that we shouldn't have
gotten.

This is a fix for CVE-2013-1940.

d16284687d xfree86: Revert workaround for drm race condition.
Revert 70739e817b and mostly revert
c31eac647a.

Further investigation shows the encountered race condition is between
lightdm and plymouth-splash, as implemented in the Ubuntu distribution
within the limitations of upstart's job coordination logic, and can (and
should) be fixed within those limiations.  Not in xserver itself.

This leaves some of the diagnostic improvements from the recent patch
series, in case others run into a similar situation.

ac4c2abe98 xserver: add monitor Option "ZoomModes" [v2]
Section "Monitor"
  Identifier "a21inch"
  Option "PreferredMode" "1600x1200"
  Option "ZoomModes" "1600x1200 1280x1024 1280x1024 640x480"
EndSection

The option's effect is to search for and mark once each named mode in
the output modes list.  So the specification order is free and the zoom
modes sequence follows the order of the output modes list.  All marked
modes are available via the Ctrl+Alt+Keypad-{Plus,Minus} key
combination.

See also http://bugs.freedesktop.org/show_bug.cgi?id=17954.

This option has its use for combined monitor and television setups.
It allows for easy switching between 60 Hz and 50 Hz modes even when a
monitor refuses to display the input signal.

(Includes a few minor changes suggested by Aaron for v2)

cf89aa5374 Full support of sRGB capable fbconfigs.
Changes to correctly initialize the sRGB capability attribute and
transfer it between XServer and the client. Modifications include
extension string, transferring visual config attribs and fbconfig
attribs. Also, attribute is initialized in the modules which do not
really use it (xquartz and xwin).
This version advertises both ARB and EXT strings, and initializes
the capability to default value of FALSE. It has corrected required
GLX version and does not influence swrast. The sRGB capable attribute
is attached only to those configs which do have this capability.
Both ARB and EXT versions share the same GLX extension enabling bit.

8f4640bdb9 randr: cleanup provider properly
So in the cold plug server shutdown case, we reap the resources
before we call CloseScreen handlers, so the config->randr_provider
is a dangling pointer when the xf86CrtcCloseScreen handler is called,

however in the hot screen unplug case, we can't rely on automatically
reaped resources, so we need to clean up the provider in the xf86CrtcCloseScreen
case.

This patch provides a cleanup callback from the randr provider removal
into the DDX so it can cleanup properly, this then gets called by the automatic
code for cold plug, or if hot unplug it gets called explicitly.

Fixes a number of random server crashes on shutdown

Instead of defaulting to -intel for Oaktrail, Medfield, and CDV chips,
default to -fbdev.  For Poulsbo (only), attempt to use -psb if it's
installed, and fallback to fbdev otherwise.  All other Intel chips
should use -intel.

This fixed an issue where -intel would load on these chips and cause a
boot failure.  Newer -intel drivers avoid the boot hang, but it's still
the wrong driver to load, so why take chances.

The patch was originally created by Stefan Dirsch for OpenSUSE.  We have
included it in our stable release (Ubuntu "quantal" 12.10) since

9f79e93b6b Short-cut the input device cleanup process during AbortServer()
If we're about to abort, we're already in the signal handler and cannot call
down to the default device cleanup routines (which reset, free, alloc, and
do a bunch of other things).

Add a new DEVICE_ABORT mode to signal a driver's DeviceProc that it must
reset the hardware if needed but do nothing else. An actual HW reset is only
required for some drivers dealing with the HW directly.

This is largely backwards-compatible, hence the input ABI minor bump only.

Drivers we care about either return BadValue on a mode that's not
DEVICE_{INIT|ON|OFF|CLOSE} or print an error and return BadValue. Exception
here is vmmouse, which currently ignores it and would not reset anything.
This should be fixed if the reset is required.

1058fcf57f dmx: don't include dmx-config.h from xdmxconfig (#37502)
dmx-config.h is a server header which includes dix-config.h. That again
defines a bunch of server-specifics, including setting the size of XID to
32 bit.

libX11 uses unsigned long (8 bits on x86_64). XGCValues thus ends up being
16 bytes smaller in xdmxconfig than in the library, causing garbage to be
sent to the server.
