I'm sorry I completely forgot to test the previous commit.
Also remove some long unused patch.

-Subject: [PATCH] Avoid use-after-free in dix/dixfonts.c: doImageText()
- [CVE-2013-4396]
-
-Save a pointer to the passed in closure structure before copying it
-and overwriting the *c pointer to point to our copy instead of the
-original.  If we hit an error, once we free(c), reset c to point to
-the original structure before jumping to the cleanup code that
-references *c.
-
-Since one of the errors being checked for is whether the server was
-able to malloc(c->nChars * itemSize), the client can potentially pass
-a number of characters chosen to cause the malloc to fail and the
-error path to be taken, resulting in the read from freed memory.
-
-Since the memory is accessed almost immediately afterwards, and the
-X server is mostly single threaded, the odds of the free memory having
-invalid contents are low with most malloc implementations when not using
-memory debugging features, but some allocators will definitely overwrite
-the memory there, leading to a likely crash.

-Subject: 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.
