In linux kernel since version 6.6.86 (release Date: 2025-04-07)
Power ISA v3.0 and later implementations in the Linux Compliancy Subset
and lower are not required to implement broadcast TLBIE instructions.
Platforms with CPUs that do implement TLBIE broadcast, that is, where
a TLB invalidation instruction performed on one CPU operates on the
TLBs of all CPUs in the system, should select this option. If this
option is selected, the disable_tlbie kernel command line option can
be used to cause global TLB invalidations to be done via IPIs; without
it, IPIs will be used unconditionally.
