The recent changes to TLB handling broke the PS3 build: arch/powerpc/include/asm/book3s/64/tlbflush.h:30: undefined reference to `.hash__tlbiel_all' Fix it by adding an fallback version of tlbiel_all() for non-native builds. It should never be called, due to checks in callers so it calls BUG(). We should probably clean it up further but this will suffice for now.
