Update of TLB shootdown code for UV3.
Kernel function native_flush_tlb_others() calls
uv_flush_tlb_others() on UV to invalidate tlb page definitions
on remote cpus. The UV systems have a hardware 'broadcast assist
unit' which can be used to broadcast shootdown messages to all
cpu's of selected nodes.
The behavior of the BAU has changed only slightly with UV3:
- UV3 is recognized with is_uv3_hub().
- UV2 functions and structures (uv2_xxx) are in most cases
simply renamed to uv2_3_xxx.
- Some UV2 error workarounds are not needed for UV3.
(see uv_bau_message_interrupt and enable_timeouts)
