Does anybody know if that change was intentional? I thought the plan
was to allow non-consistency-model arches to still use livepatch, and
that they'd just have to 'force' patches to completion instead. That
seems a little more forgiving.
The initial proposal was to allow 'force' feature on architectures
without HAVE_RELIABLE_STACKTRACE support and use pr_notice() to warn
user about the non-availability of consistency model. It was argued
against, as it will encourage people to use it as an alternative instead
of adding HAVE_RELIABLE_STACKTRACE support to the kernel.
