Dereferencing a user pointer directly from kernel-space without going
through the copy_from_user family of functions is a bad idea. Two of
such usages can be found in the sendmsg code path called from sendmmsg,
added by

commit c71d8ebe upstream.
commit 5b47b803 in the 3.0-stable tree.

Usages are performed through memcmp() and memcpy() directly. Fix those
by using the already copied msg_sys structure instead of the __user *msg
structure. Note that msg_sys can be set to NULL by verify_compat_iovec()
or verify_iovec(), which requires additional NULL pointer checks.

Dave Jones reported a lockdep splat triggered by an arp_process() call
from parp_redo().

Commit faa9dcf7 (arp: RCU changes) is the origin of the bug, since
it assumed arp_process() was called under rcu_read_lock(), which is not
true in this particular path.

Instead of adding rcu_read_lock() in parp_redo(), I chose to add it in
neigh_proxy_process() to take care of IPv6 side too.

When we enter a 32-bit system call via SYSENTER or SYSCALL, we shuffle
the arguments to match the int $0x80 calling convention.  This was
probably a design mistake, but it's what it is now.  This causes
errors if the system call as to be restarted.

For SYSENTER, we have to invoke the instruction from the vdso as the
return address is hardcoded.  Accordingly, we can simply replace the
jump in the vdso with an int $0x80 instruction and use the slower
entry point for a post-restart.

wl1271_sdio_power_on checks if the return value of pm_runtime_get_sync
is non-zero, and if so bails out.
However, pm_runtime_get_sync can return a positive number which does not
suggest an error has occurred. This is problematic for two reasons:

1. The function will needlessly bail out without decrementing back the
   runtime PM reference counter.
2. wl1271_power_on only checks if wl1271_power_on return value is
   negative. This means that wl1271_power_on will continue even if
   wl1271_sdio_power_on bailed out. As a result, sdio transactions will
   be initiated without properly enabling the sdio function and claiming
   the host. This could even lead to a kernel panic.

Fix this by only checking that the return value of pm_runtime_get_sync
is non-negative.

The testmode NVS push command is no longer in use. In addition, it has
several implementation issues that prevent it from working correctly:

1. wl1271_tm_cmd_configure relies on wl->chip.id being set. However,
   since the device was not necessarily booted by the time the function
   is called, wl->chip.id will be initialized to 0.
2. The NVS file is fetched by calling request_firmware() before it is
   possible to push an NVS file.
3. The maximum allowed size of nl binary payloads is not sufficient for
   pushing NVS files.
4. Pushing 128x NVS files will always fail due to a bug in the
   validation code.
5. In case the pushed NVS file is found invalid, the mutex will be kept
   locked and the nvs member will become a dangling pointer.

Since this feature is not being used, remove it completely instead of
fixing it.

This reverts commit f3637a5f.

It turns out that this breaks several drivers, one example being OMAP
boards which use the on-board OMAP UARTs and the omap-serial driver that
will not boot to userspace after the commit.

Paul Walmsley reports that enabling CONFIG_DEBUG_SHIRQ reveals 'IRQ
handler type mismatch' errors:

  IRQ handler type mismatch for IRQ 74
  current handler: serial idle
  ...

and the reason is that setting IRQF_ONESHOT will now result in those
interrupt handlers having different IRQF flags, and thus being
unsharable.  So the commit log in the reverted commit:

                            "Since it is required for those users and
    there is no difference for others it makes sense to add this flag
    unconditionally."

is simply not true: there may not be any difference from a "actions at
irq time", but there is a *big* difference wrt this flag testing irq
management (see __setup_irq() in kernel/irq/manage.c).

One solution may be to stop verifying IRQF_ONESHOT in __setup_irq(), but
right now the safe course of action is to revert the change.  Let's
revisit this in a later merge window.

The wiimote reports data in several data reporting modes (DRM). The DRM
request makes the wiimote send data in the requested drm.

The DRM mode can be set explicitely or can be chosen by the driver. To let
the driver choose the DRM mode, pass WIIPROTO_REQ_NULL placeholder to it. This
is no valid request and is replaced with an appropriate DRM.

Currently, the driver always sets the basic DRM_K mode, but this will be
