Please pull from git://git.infradead.org/~dwmw2/solos-2.6.git

This contains a bunch of updates to the Solos PCI driver (full patch
below for review):

David Woodhouse (27):
      solos: Fix length header in FPGA transfers
      solos: Clean up firmware loading code
      solos: Kill global 'opens' count.
      solos: Handle attribute show/store in kernel more sanely
      solos: Add initial list of parameters
      solos: Handle new line status change packets, hook up to ATM layer info
      solos: Kill existing connections on link down event
      solos: Reject non-AAL5 connections.... for now
      solos: Add SNR and Attn to status packet, fix oops on load
      solos: Fix under-allocation of skb size for get/set parameters
      solos: Remove parameter group from sysfs on ATM dev deregister
      solos: First attempt at DMA support
      solos: Tidy up DMA handling a little. Still untested
      solos: Tidy up tx_mask handling for ports which need TX
      solos: Remove unused loopback debug stuff
      solos: Remove IRQF_DISABLED, don't frob IRQ enable on the FPGA in solos_irq()
      solos: Remove superfluous wait_queue_head_t from struct solos_param
      solos: Fix various bugs in status packet handling
      solos: Clean up handling of card->tx_mask a little
      solos: Remove debugging, commented-out test code
      solos: Add 'reset' module parameter to reset the DSL chips on load
      solos: Tidy up status interrupt handling, cope with 'ERROR' status
      solos: Don't clear config registers at startup
      solos: Set RX empty flag at startup only for !dma mode
      solos: Swap upstream/downstream rates in status packet, clean up some more
      solos: Reset device on unload, free pending skbs
      solos: Disable DMA until we have an FPGA update with it actually implemented.

Nathan Williams (1):
      solos: Automatically determine number of ports

Simon Farnsworth (2):
      solos: Slight debugging improvements
      solos: FPGA and firmware update support.
