34cb275283 UIO: Fix concurrency issue
In a SMP case there was a race condition issue between
uio_pdrv_genirq_irqcontrol() running on one CPU and irq handler on
another CPU. Fix it by spin_locking shared resources access inside irq
handler.  Also:
  - Change disable_irq to disable_irq_nosync to avoid deadlock, because
    disable_irq waits for the completion of the irq handler;
  - Change atomic bit-manipulation routines to their non-atomic
    counterparts as we already are guarding the code by spinlock.

585d98e00b char: misc: assign file->private_data in all cases
In fa1f68db6c ("drivers: misc: pass miscdevice pointer via file
private data"), the misc driver infrastructure was changed to assigned
file->private_data as a pointer to the 'struct miscdevice' that
corresponds to the device being opened.

However, this assignment was only done when the misc driver was
declaring a driver-specific ->open() operation in its
file_operations. This doesn't make sense, as the driver may not
necessarily have a custom ->open() operation, and might still be
interested in having file->private_data properly set for use in its
->read() and write() operations.

Therefore, we move the assignment of file->private_data outside of the
condition that tests whether a driver-specific ->open() operation was
defined.

2608fb6531 drivers: hv: allocate synic structures before hv_synic_init()
We currently allocate synic structures in hv_sync_init(), but there's no way for
the driver to know about the allocation failure and it may continue to use the
uninitialized pointers. Solve this by introducing helpers for allocating and
freeing and doing the allocation before the on_each_cpu() call in
vmbus_bus_init().

77864f2e0a FMC: add core bus driver
This module offers registration services for both carriers
(i.e. devices) and mezzanines (i.e. drivers). The matching for devices
and drivers is performed according to the IPMI standard for FRU
devices (Field Replaceable Units).

The code includes support for parsing an SDB tree if present in the FPGA,
and dumping it for diagnostics. SDB is not mandatory.

of the project hosted on ohwr.org.

 "These are a little later than I planned on since I got caught up with
  handling merges for 3.11 most of the week.

  Another week, another batch of fixes for arm-soc platforms.

  Again, nothing controversial.  A few more than would be ideal, but all
  are valid fixes.  In particular the prima2 panic patch is critical
  since it fixes a problem where multiplatform kernels panic on all but
  prima2 hardware."

Pull networking fixes from David Miller:

 1) Fix RTNL locking in batman-adv, from Matthias Schiffer.

 2) Don't allow non-passthrough macvlan devices to set NOPROMISC via
    netlink, otherwise we can end up with corrupted promisc counter
    values on the device.  From Michael S Tsirkin.

 3) Fix stmmac driver build with debugging defines enabled, from Dinh
    Nguyen.

    terminated, from Daniel Borkmann.

 5) Fix leaking of two uninitialized bytes of memory to userspace in
    l2tp, from Guillaume Nault.

 6) Clear IPCB(skb) before tunneling otherwise we touch dangling IP
    options state and crash.  From Saurabh Mohan.

 7) Fix suspend/resume for davinci_mdio by using suspend_late and
    resume_early.  From Mugunthan V N.

 8) Don't tag ip_tunnel_init_net and ip_tunnel_delete_net with

f21afc25f9 smp.h: Use local_irq_{save,restore}() in !SMP version of on_each_cpu().
Thanks to commit f91eb62f71 ("init: scream bloody murder if interrupts
are enabled too early"), "bloody murder" is now being screamed.

With a MIPS OCTEON config, we use on_each_cpu() in our
irq_chip.irq_bus_sync_unlock() function.  This gets called in early as a
result of the time_init() call.  Because the !SMP version of
on_each_cpu() unconditionally enables irqs, we get:

    WARNING: at init/main.c:560 start_kernel+0x250/0x410()
    Interrupts were enabled early
    CPU: 0 PID: 0 Comm: swapper Not tainted 3.10.0-rc5-Cavium-Octeon+ #801
    Call Trace:
      show_stack+0x68/0x80
      warn_slowpath_common+0x78/0xb0
      warn_slowpath_fmt+0x38/0x48
      start_kernel+0x250/0x410

Suggested fix: Do what we already do in the SMP version of
on_each_cpu(), and use local_irq_save/local_irq_restore.  Because we
need a flags variable, make it a static inline to avoid name space
issues.

[ Change from v1: Convert on_each_cpu to a static inline function, add
  #include <linux/irqflags.h> to avoid build breakage on some files.

  on_each_cpu_mask() and on_each_cpu_cond() suffer the same problem as
  on_each_cpu(), but they are not causing !SMP bugs for me, so I will
  defer changing them to a less urgent patch. ]
