"If Arm could". For 32-bit, Arm Ltd isn't going to do anything, it's
old as far as they're concerned. It's up to those participating in the
kernel community to maintain and look after the code.

Thus, if there is a desire for something other than stop_machine() then
it is up to those who care about the issue to do something about it,
rather than expecting someone else to do something for them.
