Pull futex fix from Ingo Molnar:

 - Also allocate a default private futex hash on vfork() as well, to
   avoid races with (private) futex waiters (Peter Zijlstra)

+Software cursor for VGA
+=======================
+
+by Pavel Machek <pavel@atrey.karlin.mff.cuni.cz>
+and Martin Mares <mj@atrey.karlin.mff.cuni.cz>
+
+Linux now has some ability to manipulate cursor appearance.  Normally,
+you can set the size of hardware cursor.  You can now play a few new
+tricks: you can make your cursor look like a non-blinking red block,
+make it inverse background of the character it's over or to highlight
+that character and still choose whether the original hardware cursor
+should remain visible or not.  There may be other things I have never
+thought of.
+
+The cursor appearance is controlled by a ``<ESC>[?1;2;3c`` escape sequence
+where 1, 2 and 3 are parameters described below. If you omit any of them,
+they will default to zeroes.
+
+first Parameter
+	specifies cursor size::
+
+		0=default
+		1=invisible
+		2=underline,
+		...
+		8=full block
+		+ 16 if you want the software cursor to be applied
+		+ 32 if you want to always change the background color
+		+ 64 if you dislike having the background the same as the
+		     foreground.
+
+	Highlights are ignored for the last two flags.
+
+second parameter
+	selects character attribute bits you want to change
+	(by simply XORing them with the value of this parameter). On standard
+	VGA, the high four bits specify background and the low four the
+	foreground. In both groups, low three bits set color (as in normal
+	color codes used by the console) and the most significant one turns
+	on highlight (or sometimes blinking -- it depends on the configuration
+	of your VGA).
+
+third parameter
+	consists of character attribute bits you want to set.
+
+	Bit setting takes place before bit toggling, so you can simply clear a
+	bit by including it in both the set mask and the toggle mask.
+
+Examples
+--------
+
+To get normal blinking underline, use::
+
+	echo -e '\033[?2c'
+
+To get blinking block, use::
+
+	echo -e '\033[?6c'
+
+To get red non-blinking block, use::
+
+	echo -e '\033[?17;0;64c'
