The 'exynos-drm-hdmi' driver makes use of s5p-tv platform devices. Therefore
the driver should use the same platform data to prevent crashes caused by
dereferencing incorrect types. This patch corrects the exynos-drm-hdmi driver

The syscall tracing patch introduces a compile bug in lttng-modules
when the latter calls syscall_get_nr(), similar to the following:
<path-to-linux>/arch/arm/include/asm/syscall.h:21:2: error: implicit declaration of function 'task_thread_info' [-Werror=implicit-function-declaration]
The issue is that we are using task_thread_info() in the
syscall_get_nr() function in asm/syscall.h, but not explicitly
including sched.h from this file, so we can expect this bug might
surface any time that syscall_get_nr() is called.
Explicitly including sched.h solves the problem.

When we stop the tick in idle, we save the current jiffies value
in ts->idle_jiffies. This snapshot is substracted from the later
value of jiffies when the tick is restarted and the resulting
delta is accounted as idle cputime. This is how we handle the
idle cputime accounting without the tick.
But sometimes we need to schedule the next tick to some time in
the future instead of completely stopping it. In this case, a
tick may happen before we restart the periodic behaviour and
from that tick we account one jiffy to idle cputime as usual but
we also increment the ts->idle_jiffies snapshot by one so that
when we compute the delta to account, we substract the one jiffy
we just accounted.
To prepare for stopping the tick outside idle, we introduced a
check that prevents from fixing up that ts->idle_jiffies if we
are not running the idle task. But we use idle_cpu() for that
and this is a problem if we run the tick while another CPU
remotely enqueues a ttwu to our runqueue:
CPU 0: CPU 1:
tick_sched_timer() { ttwu_queue_remote()
if (idle_cpu(CPU 0))
ts->idle_jiffies++;
}
Here, idle_cpu() notes that &rq->wake_list is not empty and
hence won't consider the CPU as idle. As a result,
ts->idle_jiffies won't be incremented. But this is wrong because
we actually account the current jiffy to idle cputime. And that
jiffy won't get substracted from the nohz time delta. So in the
end, this jiffy is accounted twice.
Fix this by changing idle_cpu(smp_processor_id()) with
is_idle_task(current). This way the jiffy is substracted
correctly even if a ttwu operation is enqueued on the CPU.

The Cintiq 24HD touch cannot use wacom_set_phy_from_res to determine
the physical size of the touch sensor since the pen and touch are
on separate USB devices. The physical size is, however, provided in
the HID descriptor, just scaled to a unit we don't use.
This patch introduces the function wacom_fix_phy_from_hid to let
us make use of the unit and exponent data provided by HID to set
the [xy]_phy variables to an appropriate value. This function
relies on a trimmed-down version of hidinput_calc_abs_res from
the hid-input.c.

Pull MFD changes from Samuel Ortiz:
"MFD bits for the 3.7 merge window.
As usual we have a few new drivers:
- TI LP8788
- TI OMAP USB TLL
- Maxim MAX8907
- SMSC ECE1099
- Dialog Semiconductor DA9055
- A simpler syscon driver that allow us to get rid of the anatop one.
Drivers are also gradually getting Device Tree and IRQ domain support.
The following drivers got DT support:
- palmas, 88pm860x, tc3589x and twl4030-audio
And those ones now use the IRQ domain APIs:
- 88pm860x, tc3589x, db8500_prcmu
Also some other interesting changes:
- Intel's ICH LPC now supports Lynx Point
- TI's twl4030-audio added a GPO child
- tps6527 enabled its backlight subdevice
- The twl6030 pwm driver moved to the new PWM subsystem
And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x,
palmas, ab8500, wm8994, wm5110, max8907 and the tps65xxx family."
Fix up various annoying conflicts: the DT and IRQ domain support came in

After fixing a couple of brainos, it even seems to work. What's done here
is move of ->syscall_noerror right before FPDEPTH byte in ->flags and
using sth to [%g6 + TI_SYS_NOERROR] instead of stb to [%g6 + TI_FPDEPTH] in
both branches of etrap_save. AFAICS, that ought to be solid. Again,
deciding what to do with now unused delay slot of branch on ->syscall_noerror
and dealing with the order of tests in ret_from_sys is a separate question,
but at least that way we don't have to clean ->syscall_noerror in there at
all. AFAICS, it ought to be a clear win - sth is not going to cost more than
stb on etrap_64.S side of things, and we are losing write on syscalls.S one.

When large buffers are sent over connected TIPC sockets, it
is likely that the sk_backlog will be filled up on the
receiver side, but the TIPC flow control mechanism is happily
unaware of this since that is based on message count.
The sender will receive a TIPC_ERR_OVERLOAD message when this occurs
and drop it's side of the connection, leaving it stale on
the receiver end.
By increasing the sk_rcvbuf to a 'worst case' value, we avoid the
overload caused by a full backlog queue and the flow control
will work properly.
This worst case value is the max TIPC message size times
the flow control window, multiplied by two because a sender
will transmit up to double the window size before a port is marked
congested.
We multiply this by 2 to account for the sk_buff and other overheads.

Suppose we have an SCTP connection with two paths. After connection is
established, path1 is not available, thus this path is marked as inactive. Then
traffic goes through path2, but for some reasons packets are delayed (after
rto.max). Because packets are delayed, the retransmit mechanism will switch
again to path1. At this time, we receive a delayed SACK from path2. When we
update the state of the path in sctp_check_transmitted(), we do not take into
account the source address of the SACK, hence we update the wrong path.

commit d2d68ba9fe8 (ipv4: Cache input routes in fib_info nexthops.)
introduced a regression for forwarding.
This was hard to reproduce but the symptom was that packets were
delivered to local host instead of being forwarded.
David suggested to add fib_type to fib_info so that we dont
inadvertently share same fib_info for different purposes.
With help from Julian Anastasov who provided very helpful
hints, reproduced here :
<quote>
Can it be a problem related to fib_info reuse
from different routes. For example, when local IP address
is created for subnet we have:
broadcast 192.168.0.255 dev DEV proto kernel scope link src
192.168.0.1
192.168.0.0/24 dev DEV proto kernel scope link src 192.168.0.1
local 192.168.0.1 dev DEV proto kernel scope host src 192.168.0.1
The "dev DEV proto kernel scope link src 192.168.0.1" is
a reused fib_info structure where we put cached routes.
The result can be same fib_info for 192.168.0.255 and
192.168.0.0/24. RTN_BROADCAST is cached only for input
routes. Incoming broadcast to 192.168.0.255 can be cached
and can cause problems for traffic forwarded to 192.168.0.0/24.
So, this patch should solve the problem because it
separates the broadcast from unicast traffic.
And the ip_route_input_slow caching will work for
local and broadcast input routes (above routes 1 and 3) just
because they differ in scope and use different fib_info.

Since commit:
6d99c4c can: mpc5xxx_can: make data used as *of_device_id.data const
both "struct mpc5xxx_can_data mpc5200_can_data" and "mpc5121_can_data" are
marked as "const" but also as "__devinitdata". This leads to the following
compile error:
drivers/net/can/mscan/mpc5xxx_can.c:383: error: mpc5200_can_data causes a section type conflict
drivers/net/can/mscan/mpc5xxx_can.c:383: error: mpc5200_can_data causes a section type conflict
drivers/net/can/mscan/mpc5xxx_can.c:388: error: mpc5121_can_data causes a section type conflict
drivers/net/can/mscan/mpc5xxx_can.c:388: error: mpc5121_can_data causes a section type conflict
This patch changes the "__devinitdata" to "__devinitconst" and marks the
"struct of_device_id mpc5xxx_can_table" as "const" and "__devinitconst", too.

Convert a nonnegative error return code to a negative one, as returned
elsewhere in the function.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
{ ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
when != &ret
*if(...)
{
... when != ret = e2
when forall
return ret;
}
// </smpl>

The m68k arch doesn't have a kvm_para.h (unlike most or maybe all other
arches), but there is one in asm-generic. This means that:
ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \
$(srctree)/include/asm-$(SRCARCH)/kvm_para.h \
$(INSTALL_HDR_PATH)/include/asm-*/kvm_para.h),)
header-y += kvm_para.h
endif
gets it wrong because it is invoked twice during the header installation - and
on the second occasion, asm-generic/kvm_para.h has been installed in usr/,
thus triggering a attempt to install asm-m68k/kvm_para.h which will fail.
There are three headers with this sort of conditional logic: a.out.h, kvm.h
and kvm_para.h. For all three of them, change the logic to be something like:
ifneq ($(wildcard $(srctree)/arch/$(SRCARCH)/include/asm/kvm_para.h \
$(srctree)/arch/$(SRCARCH)/include/uapi/asm/kvm_para.h),)
which finds the header in only the two places it should be found, and doesn't
get incorrectly triggered by the installation of asm-generic's version.

This reverts commit 8b28626a6b1522b39f75d0bf80d5dec23c931f5a.
Offset -8 is wrong because when it is applied then one instruction
before brki r14, 8 is called again when we return.
Offset -4 is correct and brki instruction is called again.
This change came from ancient MMU kernel.

I can't even find how I figured this might be needed anymore. But sure
enough, the value I'm reading back on platforms doesn't match what the
docs recommends.
It seemed to fix Chris' GT1 in limited testing as well.
