But this pretty much means that such systems cannot be SMP systems at
all. Im

Power ISA v3.1 implementations in the Linux Compliancy Subset and
lower are not required to implement broadcast TLBIE, and in fact
Microwatt doesn't. To avoid the need to specify "disable_tlbie" on
the kernel command line on SMP Microwatt systems, this defines a
config option that asserts that bro
