nfs4.1: add BIND_CONN_TO_SESSION operation

This patch adds the BIND_CONN_TO_SESSION operation which is needed for
upcoming SP4_MACH_CRED work and useful for recovering from broken connections
without destroying the session.

solos-pci: Fix DMA support

DMA support has finally made its way to the top of the TODO list, having
realised that a Geode using MMIO can't keep up with two ADSL2+ lines
each running at 21Mb/s.

This patch fixes a couple of bugs in the DMA support in the driver, so
once the corresponding FPGA update is complete and tested everything
should work properly.

We weren't storing the currently-transmitting skb, so we were never
unmapping it and never freeing/popping it when the TX was done.
And the addition of pci_set_master() is fairly self-explanatory.

xen/netback: Calculate the number of SKB slots required correctly

When calculating the number of slots required for a packet header, the code
was reserving too many slots if the header crossed a page boundary. Since
netbk_gop_skb copies the header to the start of the page, the count of
slots required for the header should be based solely on the header size.

This problem is easy to reproduce if a VIF is bridged to a USB 3G modem
device as the skb->data value always starts near the end of the first page.

sparc: Fix user_addr_max() definition.

We need to use TASK_SIZE because for 64-bit tasks the value
of STACK_TOP actually sits in the middle of the address space
so we'll get false-negatives.

Adjust the TASK_SIZE definition on sparc64 to accomodate this,
in the context in which user_addr_max() is used we have the
test_thread_flag() definition available but not the one for
test_tsk_thread_flag().

Pull more relocation fixes from Peter Anvin:
 "These are additional symbols that have been found to either be
  absolute or look like they might end up being absolute on one version

  GNU ld version, 2.21, can generate bogus absolute symbols; again, this
  would have caused a malfunctioning kernel on x86-32 if relocated.

  The relocs.c changes changed silent corruption to a build time error.

  It is worth noting that if the various barrier symbols we use were
  more consistent in the namespace used this probably could be reduced
  to a single regexp; if nothing else it looks like there is migration
  toward a common __(start|stop)___.* namespace."
