Firstly, if the direction is TODEVICE, then dirty data in the
streaming cache is impossible so we can elide the flush-flag
synchronization in that case.

Next, the context allocator is broken.  It is highly likely
that contexts get used multiple times for different dma
mappings, which confuses the strbuf flushing code and makes
it run inefficiently.

[ This is take 2: make the length check be for 16-byte alignment, not
  just word alignment.  That should hopefully keep everybody happy,
  while still allowing CD writing with DMA ]

Add tg3_nvram_lock() and tg3_nvram_unlock() calls around tg3_halt_cpu().
It is possible that the bootcode may be loading code from nvram during
this call and stopping the cpu without getting the lock may cause
uncompleted nvram data to be left in the nvram data register. Subsequent
calls to read/write nvram data will fail.

This improves the bridge local receive path by avoiding going
through another softirq.  The bridge receive path is already being called
from a netif_receive_skb() there is no point in going through another
receiveq round trip.

Recursion is limited because bridge can never be a port of a bridge
so handle_bridge() always returns.

The error checking for emulation of load string instructions was overly
generous and would cause certain valid forms of the instructions to be
treated as illegal.  We drop the range checking since the architecture
allows this to be boundedly undefined.  Tests on CPUs that support these
instructions appear not do cause illegal instruction traps on range errors
and just allow the execution to occur.

Thanks to Kim Phillips for debugging this and figuring out what real HW was
doing.

board-specific bits for 8272ADS and PQ2FADS; the related files were renamed
