This patch runs into context mismatches because of changes made by
Michael Ellerman's patch "Fix sparse warnings in
arch/powerpc/platforms/pseries" (now in Linus' tree), which changed
code like

	if (condition)
		return function_returning_void(args);

into

	if (condition) {
		function_returning_void(args);
		return;
	}

which will cause problems for your patch.  Please check if any of
these changes need to be undone again.

Paul.
