Add proper device tree support for SEMA4 driver. Also rename the
source and header file to the mainline SoC name "vf610_".

Extend the MSCM driver with CPU2CPU interrupt support. Those
interrupts are mainly used for the external MCC kernel module
which uses the functionality to pass messages to the secondary
Cortex-M4 core.
In Timesys version (at least up to 1.06), the interrupt handling
was directly done in the MCC kernel module. However, because newer
kernels use virtual interrupt numbers, it is not possible to use
hardcoded hardware IRQ number by default. By requesting the
interupts within the MSCM driver and exporting some helper
functions.

Added platform data struct to define interrupt and reset GPIO. This
allows to initialize the touchscreen controller inside the driver
rather then in each platform and use the driver as a module.

The 2-bit gates found i.MX and Vybrid SoC support different clock
configuration:
0b00: clk disabled
0b01: clk enabled in RUN mode but disabled in WAIT and STOP mode
0b10: clk enabled in RUN, WAIT and STOP mode (only Vybrid)
0b11: clk enabled in RUN and WAIT mode
For some clocks, we might want to configure different behaviour,
e.g. a memory clock should be on even in STOP mode. Add a new
function imx_clk_gate2_cgr which allow to configure specific
gate values through the cgr_val parameter.

TCP timestamping introduced MSG_ERRQUEUE handling for TCP sockets.
If the socket is of family AF_INET6, call ipv6_recv_error instead
of ip_recv_error.
This change is more complex than a single branch due to the loadable
ipv6 module. It reuses a pre-existing indirect function call from
ping. The ping code is safe to call, because it is part of the core
ipv6 module and always present when AF_INET6 sockets are active.

Jonathan writes:
Third set of IIO fixes for the 3.18 cycle.
Most of these are fairly standard little fixes, a bmc150 and bmg160 patch
is to make an ABI change to indicated a specific axis in an event rather
than the generic option in the original drivers. As both of these drivers
are new in this cycle it would be ideal to push this minor change through
even though it isn't strictly a fix. A couple of other 'fixes' change
defaults for some settings on these new drivers to more intuitive calues.
Looks like some useful feedback has been coming in for this driver
since it was applied.
* IIO_EVENT_CODE_EXTRACT_DIR bit mask was wrong and has been for a while
0xCF clearly doesn't give a contiguous bitmask.
* kxcjk-1013 range setting was failing to mask out the previous value
in the register and hence was 'enable only'.
* men_z188 device id table wasn't null terminated.
* bmg160 and bmc150 both failed to correctly handling an error in mode
setting.
* bmg160 and bmc150 both had a bug in setting the event direction in the
event spec (leads to an attribute name being incorrect)
* bmg160 defaulted to an open drain output for the interrupt - as a default
this obviously only works with some interrupt chips - hence change the
default to push-pull (note this is a new driver so we aren't going to
cause any regressions with this change).
* bmc150 had an unintuitive default for the rate of change (motion detector)
so change it to 0 (new driver so change of default won't cause any
regressions).

This reverts commit 85c8555ff0 ("KVM: check for !is_zero_pfn() in
kvm_is_mmio_pfn()") and renames the function to kvm_is_reserved_pfn.
The problem being addressed by the patch above was that some ARM code
based the memory mapping attributes of a pfn on the return value of
kvm_is_mmio_pfn(), whose name indeed suggests that such pfns should
be mapped as device memory.
However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin,
and the existing non-ARM users were already using it in a way which
suggests that its name should probably have been 'kvm_is_reserved_pfn'
from the beginning, e.g., whether or not to call get_page/put_page on
it etc. This means that returning false for the zero page is a mistake
and the patch above should be reverted.

percpu-ref: fix DEAD flag contamination of percpu pointer
|
|
While decoupling ATOMIC and DEAD flags, f47ad4578461 ("percpu_ref:
decouple switching to percpu mode and reinit") updated
__ref_is_percpu() so that it only tests ATOMIC flag to determine
whether the ref is in percpu mode or not; however, while DEAD implies
ATOMIC, the two flags are set separately during percpu_ref_kill() and
if __ref_is_percpu() races percpu_ref_kill(), it may see DEAD w/o
ATOMIC. Because __ref_is_percpu() returns @ref->percpu_count_ptr
value verbatim as the percpu pointer after testing ATOMIC, the pointer
may now be contaminated with the DEAD flag.
This can be fixed by clearing the flag bits before returning the
pointer which was the fix proposed by Shaohua; however, as DEAD
implies ATOMIC, we can just test for both flags at once and avoid the
explicit masking.
Update __ref_is_percpu() so that it tests that both ATOMIC and DEAD
are clear before returning @ref->percpu_count_ptr as the percpu
pointer.

Marc Kleine-Budde says:
====================
pull-request: can 2014-11-18
this is a pull request of 17 patches for net/master for the v3.18 release
cycle.
The last patch of this pull request ("can: m_can: update to support CAN FD
features") adds, as the description says, a new feature to the m_can driver. As
the m_can driver has been added in v3.18 there is no risk of causing a
regression. Give me a note if this is not okay and I'll create a new pull
request without it.
There is a patch for the CAN infrastructure by Thomas Körper which fixes
calling kfree_skb() from interrupt context. Roman Fietze fixes a typo also in
the infrastructure. A patch by Dong Aisheng adds a generic helper function to
tell if a skb is normal CAN or CAN-FD frame. Alexey Khoroshilov of the Linux
Driver Verification project fixes a memory leak in the esd_usb2 driver. Two
patches by Sudip Mukherjee remove unused variables and fixe the signess of a
variable. Three patches by me add the missing .ndo_change_mtu callback to the
xilinx_can, rcar_can and gs_usb driver.
The remaining patches improve the m_can driver: David Cohen adds the missing
CONFIG_HAS_IOMEM dependency. Dong Aisheng provides 6 bugfix patches (most
important: missing RAM init, sleep in NAPI poll, dlc in RTR). While the last of
his patches adds CAN FD support to the driver.

Commit 79c6ab509558 (clk: divider: add CLK_DIVIDER_READ_ONLY flag) in
v3.16 introduced the CLK_DIVIDER_READ_ONLY flag which caused the
recalc_rate() and round_rate() clock callbacks to be omitted.
However using this flag has the unfortunate side effect of causing the
clock recalculation code when a clock rate change is attempted to always
treat it as a pass-through clock, i.e. with a fixed divide of 1, which
may not be the case. Child clock rates are then recalculated using the
wrong parent rate.
Therefore instead of dropping the recalc_rate() and round_rate()
callbacks, alter clk_divider_bestdiv() to always report the current
divider as the best divider so that it is never altered.
For me the read only clock was the system clock, which divided the PLL
rate by 2, from which both the UART and the SPI clocks were divided.
Initial setting of the UART rate set it correctly, but when the SPI
clock was set, the other child clocks were miscalculated. The UART clock
was recalculated using the PLL rate as the parent rate, resulting in a
UART new_rate of double what it should be, and a UART which spewed forth
garbage when the rate changes were propagated.

Pablo Neira Ayuso says:
====================
Netfilter/IPVS fixes for net
The following patchset contains Netfilter updates for your net tree,
they are:
1) Fix missing initialization of the range structure (allocated in the
stack) in nft_masq_{ipv4, ipv6}_eval, from Daniel Borkmann.
2) Make sure the data we receive from userspace contains the req_version
structure, otherwise return an error incomplete on truncated input.
From Dan Carpenter.
3) Fix handling og skb->sk which may cause incorrect handling
of connections from a local process. Via Simon Horman, patch from
Calvin Owens.
4) Fix wrong netns in nft_compat when setting target and match params
structure.
5) Relax chain type validation in nft_compat that was recently included,
this broke the matches that need to be run from the route chain type.
Now iptables-test.py automated regression tests report success again
and we avoid the only possible problematic case, which is the use of
nat targets out of nat chain type.
6) Use match->table to validate the tablename, instead of the match->name.
Again patch for nft_compat.
7) Restore the synchronous release of objects from the commit and abort
path in nf_tables. This is causing two major problems: splats when using
nft_compat, given that matches and targets may sleep and call_rcu is
invoked from softirq context. Moreover Patrick reported possible event
notification reordering when rules refer to anonymous sets.
8) Fix race condition in between packets that are being confirmed by
conntrack and the ctnetlink flush operation. This happens since the
removal of the central spinlock. Thanks to Jesper D. Brouer to looking
into this.

While looking over the cpu-timer code I found that we appear to add
the delta for the calling task twice, through:
cpu_timer_sample_group()
thread_group_cputimer()
thread_group_cputime()
times->sum_exec_runtime += task_sched_runtime();
*sample = cputime.sum_exec_runtime + task_delta_exec();
Which would make the sample run ahead, making the sleep short.

On some 32 bits architectures, including x86, GENMASK(31, 0) returns 0
instead of the expected ~0UL.
This is the same on some 64 bits architectures with GENMASK_ULL(63, 0).
This is due to an overflow in the shift operand, 1 << 32 for GENMASK,
1 << 64 for GENMASK_ULL.

Most NICs that report NETIF_F_GSO_UDP_TUNNEL support VXLAN, and not
other UDP-based encapsulation protocols where the format and size of the
header differs. This patch implements a generic ndo_gso_check() for
VXLAN which will only advertise GSO support when the skb looks like it
contains VXLAN (or no UDP tunnelling at all).
Implementation shamelessly stolen from Tom Herbert:

There could be a signed overflow in the following code.
The expression, (32-logmask) is comprised between 0 and 31 included.
It may be equal to 31.
In such a case the left shift will produce a signed integer overflow.
According to the C99 Standard, this is an undefined behavior.
A simple fix is to replace the signed int 1 with the unsigned int 1U.

Pull ACPI and power management fixes from Rafael Wysocki:
"These are three regression fixes, two recent (generic power domains,
suspend-to-idle) and one older (cpufreq), an ACPI blacklist entry for
one more machine having problems with Windows 8 compatibility, a minor
cpufreq driver fix (cpufreq-dt) and a fixup for new callback
definitions (generic power domains).
Specifics:
- Fix a crash in the suspend-to-idle code path introduced by a recent
commit that forgot to check a pointer against NULL before
dereferencing it (Dmitry Eremin-Solenikov).
- Fix a boot crash on Exynos5 introduced by a recent commit making
that platform use generic Device Tree bindings for power domains
which exposed a weakness in the generic power domains framework
leading to that crash (Ulf Hansson).
- Fix a crash during system resume on systems where cpufreq depends
on Operation Performance Points (OPP) for functionality, but
CONFIG_OPP is not set. This leads the cpufreq driver registration
to fail, but the resume code attempts to restore the pre-suspend
cpufreq configuration (which does not exist) nevertheless and
crashes. From Geert Uytterhoeven.
- Add a new ACPI blacklist entry for Dell Vostro 3546 that has
problems if it is reported as Windows 8 compatible to the BIOS
(Adam Lee).
- Fix swapped arguments in an error message in the cpufreq-dt driver
(Abhilash Kesavan).
- Fix up the prototypes of new callbacks in struct generic_pm_domain
to make them more useful. Users of those callbacks will be added
in 3.19 and it's better for them to be based on the correct struct
definition in mainline from the start. From Ulf Hansson and Kevin
Hilman"

In free_area_init_core(), zone->managed_pages is set to an approximate
value for lowmem, and will be adjusted when the bootmem allocator frees
pages into the buddy system.
But free_area_init_core() is also called by hotadd_new_pgdat() when
hot-adding memory. As a result, zone->managed_pages of the newly added
node's pgdat is set to an approximate value in the very beginning.
Even if the memory on that node has node been onlined,
/sys/device/system/node/nodeXXX/meminfo has wrong value:
hot-add node2 (memory not onlined)
cat /sys/device/system/node/node2/meminfo
Node 2 MemTotal: 33554432 kB
Node 2 MemFree: 0 kB
Node 2 MemUsed: 33554432 kB
Node 2 Active: 0 kB
This patch fixes this problem by reset node managed pages to 0 after
hot-adding a new node.
1. Move reset_managed_pages_done from reset_node_managed_pages() to
reset_all_zones_managed_pages()
2. Make reset_node_managed_pages() non-static
3. Call reset_node_managed_pages() in hotadd_new_pgdat() after pgdat
is initialized
