      Pull ARM SoC bug fixes from Arnd Bergmann:
       "A little later during the week than the last few pull requests, since
        there was very little that came in before 3.9-rc6.  At least things
        have calmed down again here.
      
        Some important bug fixes that came in over the last 10 days, mostly
        mvebu and imx:
      
         - Multiple regressions on i.mx following the conversion of the clock
           code, hopefully the last we are seeing of those.
         - a regression in the mvebu irq handling code
         - An incorrect register offset in the rewritten s3c24xx irq code.
         - Two bugs in setting up the iomega_ix2_200 machine
         - Turning on an extra bus clock on imx
         - A MAINTAINERS file entry for Roland Stigge"

      bnx2x: Prevent null pointer dereference in AFEX mode · fea75645
      Yuval Mintz authored
      The cnic module is responsible for initializing various bnx2x structs
      via callbacks provided by the bnx2x module.
      One such struct is the queue object for the FCoE queue.
      
      If a device is working in AFEX mode and its configuration allows FCoE yet
      the cnic module is not loaded, it's very likely a null pointer dereference
      will occur, as the bnx2x will erroneously access the FCoE's queue object.
      
      Prevent said access until cnic properly registers itself.

      arm: mvebu: Fix the irq map function in SMP mode · 600468d0
      Gregory CLEMENT authored
      This patch fix the regression introduced by the commit 3202bf01
      "arm: mvebu: Improve the SMP support of the interrupt controller":
      GPIO IRQ were no longer delivered to the CPUs.
      
      To be delivered to a CPU an interrupt must be enabled at CPU level and
      at interrupt source level. Before the offending patch, all the
      interrupts were enabled at source level during map() function. Mask()
      and unmask() was done by handling the per-CPU part. It was fine when
      running in UP with only one CPU.
      
      The offending patch added support for SMP, in this case mask() and
      unmask() was done by handling the interrupt source level part. The
      per-CPU level part was handled by the affinity API to select the CPU
      which will receive the interrupt. (Due to some hardware limitation
      only one CPU at a time can received a given interrupt).
      
      For "normal" interrupt __setup_irq() was called when an irq was
      registered. irq_set_affinity() is called from this function, which
      enabled the interrupt on one of the CPUs. Whereas for GPIO IRQ which
      were chained interrupts, the irq_set_affinity() was never called and
      none of the CPUs was selected to receive the interrupt.
      
      With this patch all the interrupt are enable on the current CPU during
      map() function. Enabling the interrupts on a CPU doesn't depend
      anymore on irq_set_affinity() and then the chained irq are not anymore
      a special case. However the CPU which will receive the irq can still
      be modify later using irq_set_affinity().
      
      Tested with Mirabox (A370) and Openblocks AX3 (AXP), rootfs mounted
      over NFS, compiled with CONFIG_SMP=y/N.

      NFSv4: Doh! Typo in the fix to nfs41_walk_client_list · eb04e0ac
      Trond Myklebust authored
      Make sure that we set the status to 0 on success. Missed in testing
      because it never appears when doing multiple mounts to _different_
      servers.
