It's a bit of a faff getting enum values into asm -- we actually have to
duplicate the definitions using #defines to get at the constants. Perhaps it
would be cleaner to leave context_tracking_user_{enter,exit} intact as C
wrappers around context_tracking_{enter,exit} passing the appropriate
constant? That way we don't actually need to change the arch code at all.
