Log message:
Add support for flushing the instruction cache of other processes. This is
needed for inserting and removing breakpoints through ptrace(2).
The approach here only works for CPUs that have a PIPT instruction cache
as we use aliased mappings to invalidate the instruction cache. That doesn't
work on CPUs that have a virtually indexed instruction cache.
