Pravin B Shelar 559835ea72 vxlan: Use RCU apis to access sk_user_data.
Use of RCU api makes vxlan code easier to understand.  It also
fixes bug due to missing ACCESS_ONCE() on sk_user_data dereference.
In rare case without ACCESS_ONCE() compiler might omit vs on
sk_user_data dereference.
Compiler can use vs as alias for sk->sk_user_data, resulting in
multiple sk_user_data dereference in rcu read context which
could change.

Rafael J. Wysocki aab1728915 PM / hibernate: Fix user space driven resume regression
Recent commit 8fd37a4 (PM / hibernate: Create memory bitmaps after
freezing user space) broke the resume part of the user space driven
hibernation (s2disk), because I forgot that the resume utility
loaded the image into memory without freezing user space (it still
freezes tasks after loading the image).  This means that during user
space driven resume we need to create the memory bitmaps at the
"device open" time rather than at the "freeze tasks" time, so make
that happen (that's a special case anyway, so it needs to be treated
in a special way).

Joel Fernandes 6cdaca481f ARM: edma: Fix clearing of unused list for DT DMA resources
HWMOD removal for MMC is breaking edma_start as the events are being manually
triggered due to unused channel list not being clear.

The above issue is fixed by reading the "dmas" property from the DT node if it
exists and clearing the bits in the unused channel list if the dma controller
used by any device is EDMA. For this purpose we use the of_* helpers to parse
the arguments in the dmas phandle list.

Also introduced is a minor clean up of a checkpatch error in old code.

Lorenzo Pieralisi 64270d82d4 ARM: vexpress: tc2: fix hotplug/idle/kexec race on cluster power down
On the TC2 testchip, when all CPUs in a cluster enter standbywfi
and commit a power down request, the power controller will wait
for standbywfil2 coming from L2 cache controller to shut the
cluster down.
By the time all CPUs in a cluster commit a power down request
and enter wfi, the power controller cannot backtrack, or put it
another way, a CPU must not be allowed to complete execution
independently of the power controller, the only way for it to
resume properly must be upon wake-up IRQ pending and subsequent
reset triggered from the power controller.

Current MCPM back-end for TC2 disables the GIC CPU IF only when
power down is committed through the tc2_pm_suspend() method, that
makes sense since a suspended CPU is still online and can receive
interrupts whereas a hotplugged CPU, since it is offline,
migrated all IRQs and shutdown the per-CPU peripherals, hence
their PPIs.

The flaw with this reasoning is the following. If all CPUs in
a clusters are entering a power down state either through CPU
idle or CPU hotplug, when the last man successfully completes
the MCPM power down sequence (and executes wfi), power controller
waits for L2 wfi signal to quiesce the cluster and shut it down.
If, when all CPUs are sitting in wfi, an online CPU hotplugs back
in one of the CPUs in the cluster being shutdown, that CPU
receives an IPI that causes wfi to complete (since tc2_pm_down()
method does not disable the GIC CPU IF in that case - CPU being
hotplugged out, not idle) and the power controller will never see
the stanbywfil2 signal coming from L2 that is required for
shutdown to happen and the system deadlocks.

Further to this issue, kexec hotplugs secondary CPUs out during
kernel reload/restart.
Because kexec may (deliberately) trash the old kernel text, it is
not OK for CPUs to follow the MCPM soft reboot path, since
instructions after the WFI may have been replaced by kexec.

If tc2_pm_down() does not disable the GIC cpu interface, there is a
race between CPU powerdown in the old kernel and the IPI from the
new kernel that triggers secondary boot, particularly if the
powerdown is slow (due to L2 cache cleaning for example).  If the
new kernel wins the race, the affected CPU(s) will not really be
reset and may execute garbage after the WFI.

The only solution to this problem consists in disabling the GIC
CPU IF on a CPU committed to power down regardless of the power
down entry method (CPU hotplug or CPU idle). This way, CPU wake-up
is under power controller control, which prevents unexpected wfi
exit caused by a pending IRQ.

This patch moves the GIC CPU IF disable call in the TC2 MCPM
implementation from the tc2_pm_suspend() method to the
tc2_pm_down() method to fix the mentioned race condition(s).

distributed by ARM [1]. To run their kernels, users will execute:

  $ ./Foundation_v8 --image linux-system.axf --block-device raring-rootfs

To mount the raring-rootfs filesystem, the kernel parameter should
typically include:

  root=/dev/vda

For this device to be present, the kernel must be compiled with
VIRTIO_{MMIO,BLK}. To make this work out-of-the-box, make it part of the
default configuration.

Chris Metcalf f862eefec0 tile: use a more conservative __my_cpu_offset in CONFIG_PREEMPT
It turns out the kernel relies on barrier() to force a reload of the
percpu offset value.  Since we can't easily modify the definition of
barrier() to include "tp" as an output register, we instead provide a
definition of __my_cpu_offset as extended assembly that includes a fake
stack read to hazard against barrier(), forcing gcc to know that it
must reread "tp" and recompute anything based on "tp" after a barrier.

This fixes observed hangs in the slub allocator when we are looping
on a percpu cmpxchg_double.

A similar fix for ARMv7 was made in June in change 509eb76ebf.

Marc Kleine-Budde 0d1862ea1a can: flexcan: fix flexcan_chip_start() on imx6
In the flexcan_chip_start() function first the flexcan core is going through
the soft reset sequence, then the RX FIFO is enabled.

With the hardware is put into FIFO mode, message buffers 1...7 are reserved by
the FIFO engine. The remaining message buffers are in reset default values.
This patch removes the bogus initialization of the message buffers, as it
causes an imprecise external abort on imx6.

Martin Schwidefsky dbbfe487e5 s390: fix system call restart after inferior call
Git commit 616498813b "s390: system call path micro optimization"
introduced a regression in regard to system call restarting and inferior
function calls via the ptrace interface. The pointer to the system call
table needs to be loaded in sysc_sigpending if do_signal returns with
TIF_SYSCALl set after it restored a system call context.

Michael Holzheu 4d3b0664a0 s390: Allow vmalloc target buffers for copy_from_oldmem()
Currently copy_from_oldmem() is not able to copy to virtual memory.
When using kexec pre-allocated ELF header, copy_from_oldmem()
is used to copy the ELF notes information to vmalloc buffers.

So fix this and use the new function copy_from_realmem() that allows
copying also to vmalloc memory.

TCP packets hitting the SYN proxy through the SYNPROXY target are not
validated by TCP conntrack. When th->doff is below 5, an underflow happens
when calculating the options length, causing skb_header_pointer() to
return NULL and triggering the BUG_ON().

Handle this case gracefully by checking for NULL instead of using BUG_ON().

Gabor Juhos 1b0135b5e2 avr32: fix clockevents kernel warning

   [<90000520>] start_kernel+0x128/0x23c

When the 'avr32_comparator' clockevent device is registered,
the clockevent core sets the mode of that clockevent device
to CLOCK_EVT_MODE_SHUTDOWN. Due to this, the 'comparator_mode'
function calls the 'cpu_idle_poll_ctrl' to disables idle poll.
This results in the aforementioned warning because the polling
is not enabled yet.

Change the code to only disable idle poll if it is enabled by
the same function to avoid the warning.
