[PATCH] ppc64: Fix issue with gcc 4.0 compiled kernels
I recently had a BUG_ON() go off spuriously on a gcc 4.0 compiled kernel. It turns out gcc-4.0 was removing a sign extension while earlier gcc versions would not. Thinking this to be a compiler bug, I submitted a report: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23422 It turns out we need to cast the input in order to tell gcc to sign extend it. Thanks to Andrew Pinski for his help on this bug.
