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.
Fixes: d4748276ae14 ("powerpc/64s: Improve local TLB flush for boot and MCE on
POWER9")
