--- Comment #21 from dhowells at redhat dot com <dhowells at redhat dot com> --- (In reply to Markus Trippelsdorf from comment #20) > *** Bug 78879 has been marked as a duplicate of this bug. *** Kernel bug or not, it should be noted that this means that you cannot use gcc from r236831 to compile any kernel from the introduction and use of ilog2() to the current day - and these kernel versions cannot be retroactively fixed.
