ARM: sun7i: dt: Fix interrupt trigger types

The Allwinner A20 uses the ARM GIC as its internal interrupts controller. The
GIC can work on several interrupt triggers, and the A20 was actually setting it
up to use a rising edge as a trigger, while it was actually a level high
trigger, leading to some interrupts that would be completely ignored if the
edge was missed.

Fix this for the remaining DT nodes that slipped through.

ARM: OMAP4: hwmod: Fix SOFTRESET logic for OMAP4

Commit 313a76e (ARM: OMAP2+: hwmod: Fix SOFTRESET logic) introduced
softreset bit cleaning right after set one. It is caused L3 error for
OMAP4 ISS because ISS register write occurs when ISS reset process is in
progress. Avoid this situation by cleaning softreset bit later, when reset
process is successfully finished.

ARM: OMAP2+: clock: fix clkoutx2 with CLK_SET_RATE_PARENT

If CLK_SET_RATE_PARENT is set for a clkoutx2 clock, calling
clk_set_rate() on the clock "skips" the x2 multiplier as there are no
set_rate and round_rate functions defined for the clkoutx2.

This results in getting double the requested clock rates, breaking the
display on omap3430 based devices. This got broken when
d0f58bd3bba3877fb1af4664c4e33273d36f00e4 and related patches were merged
for v3.14, as omapdss driver now relies more on the clk-framework and
CLK_SET_RATE_PARENT.

This patch implements set_rate and round_rate for clkoutx2.

Tested on OMAP3430, OMAP3630, OMAP4460.

Merge tag 'for-v3.14-rc/omap-fixes-a' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.14/fixes

Several OMAP clock/PM/device data fixes for v3.14-rc.  There's an OMAP5
reboot fix in there, plus a clock fix for rate computations involving
x2 multipliers.

Basic build, boot, and PM test logs are available here:

Note that most full-chip PM is broken since the v3.14 merge; it's
not caused by this series.

cifs: sanity check length of data to send before sending

We had a bug discovered recently where an upper layer function
(cifs_iovec_write) could pass down a smb_rqst with an invalid amount of
data in it. The length of the SMB frame would be correct, but the rqst
struct would cause smb_send_rqst to send nearly 4GB of data.

This should never be the case. Add some sanity checking to the beginning
of smb_send_rqst that ensures that the amount of data we're going to
send agrees with the length in the RFC1002 header. If it doesn't, WARN()
and return -EIO to the upper layers.

audit: Use struct net not pid_t to remember the network namespce to reply in

In struct audit_netlink_list and audit_reply add a reference to the
network namespace of the caller and remove the userspace pid of the
caller.  This cleanly remembers the callers network namespace, and
removes a huge class of races and nasty failure modes that can occur
when attempting to relook up the callers network namespace from a
pid_t (including the caller's network namespace changing, pid
wraparound, and the pid simply not being present).
