- Drop support for outdated 3590/3592 and 3480 tape devices, and limit
support to virtualized 3490E types devices
- Implement exception based WARN() and WARN_ONCE() similar to x86
- Slightly optimize preempt primitives like __preempt_count_add() and
__preempt_count_dec_and_test()
- A couple of small fixes and improvements
