Pull ARM SoC fixes from Olof Johansson:
"Another batch of fixes for ARM SoC platforms. Most are smaller fixes.
Two areas that are worth pointing out are:
- OMAP had a handful of changes to voltage specs that caused a bit of
churn, most of volume of change in this branch is due to this.
- There are a couple of _rcuidle fixes from Paul that touch common
code and came in through the OMAP tree since they were the ones who
saw the problems.
The rest is smaller changes across a handful of platforms"

Fixes for omaps for v4.7-rc cycle:
- Fix dra7 for hardware issues limiting L4Per and L3init power domains
to on state. Without this the devices may not work correctly after
some time of use because of asymmetric aging. And related to this,
let's also remove the unusable states.
- Always select omap interconnect for am43x as otherwise the am43x
only configurations will not boot properly. This can happen easily
for any product kernels that leave out other SoCs to save memory.
- Fix DSS PLL2 addresses that have gone unused for now
- Select erratum 430973 for omap3, this is now safe to do and can
save quite a bit of debugging time for people who may have left
it out.

Commit a6f75aa161c5 ("drm/exynos: fimd: add HW trigger support") added
hardware trigger support to the FIMD controller driver. But this broke

Commit 3424e3a4f844 ("drm: bridge: analogix/dp: split exynos dp driver to
bridge directory") split the Exynos DP core driver into a core driver and
a bridge driver for the Analogix chip since that is also used by Rockchip.
But the change introduced a regression causing a NULL pointer dereference
when trying to access an uninitialized connector in the driver .get_modes:
Fix this by instead of having a connector struct for both the Exynos and
Analogix drivers, just use the connector initialized in the bridge driver.

This patch fixes a non-booting issue in Mainline.
When booting with a compressed kernel, we need to be careful how we
populate memory close to DDR start. AUTO_ZRELADDR is enabled by default
in multi-arch enabled configurations, which place some restrictions on
where the kernel is placed and where it will be uncompressed to on boot.
AUTO_ZRELADDR takes the decompressor code's start address and masks out
the bottom 28 bits to obtain an address to uncompress the kernel to
(thus a load address of 0x42000000 means that the kernel will be
uncompressed to 0x40000000 i.e. DDR START on this platform).
Even changing the load address to after the co-processor's shared memory
won't render a booting platform, since the AUTO_ZRELADDR algorithm still
ensures the kernel is uncompressed into memory shared with the first
co-processor (0x40000000).
Another option would be to move loading to 0x4A000000, since this will
mean the decompressor will decompress the kernel to 0x48000000. However,
this would mean a large chunk (0x44000000 => 0x48000000 (64MB)) of
memory would essentially be wasted for no good reason.
Until we can work with ST to find a suitable memory location to
relocate co-processor shared memory, let's disable the shared memory
nodes. This will ensure a working platform in the mean time.
NB: The more observant of you will notice that we're leaving the DMU
shared memory node enabled; this is because a) it is the only one in
active use at the time of this writing and b) it is not affected by
the current default behaviour which is causing issues.

Some Dell machines have especially broken SMM or BIOS which cause that once
fan_type() is called then CPU fan speed going randomly up and down. And for
fixing this behaviour reboot is required.
So this patch creates fan_type blacklist of affected Dell machines and
disallow fan_type() call on them to prevent that erratic behaviour.
Old blacklist which disabled loading driver on some machines added in
commits a4b45b25f18d ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8100")
and 6220f4ebd7b4 ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8000") were
moved to FAN_TYPE blacklist.

default
For security reasons ordinary user must not be able to control fan speed
via /proc/i8k by default. Some malicious software running under "nobody"
user could be able to turn fan off and cause HW problems. So this patch
changes default value of "restricted" parameter to 1.
Also restrict reading of DMI_PRODUCT_SERIAL from /proc/i8k via "restricted"
parameter. It is because non root user cannot read DMI_PRODUCT_SERIAL from
sysfs file /sys/class/dmi/id/product_serial.
Old non secure behaviour of file /proc/i8k can be achieved by loading this
module with "restricted" parameter set to 0.
Note that this patch has effects only for kernels compiled with CONFIG_I8K
and only for file /proc/i8k. Hwmon interface provided by this driver was
not changed and root access for setting fan speed was needed also before.

of 'struct timespec' in place. This is harmless because 64-bit
architectures define timespec64 as timespec, and this driver is

Further analysis reveals that there are three different locations in the
socket code where tipc_sk_respond() is called within the context of the
socket lock, with ensuing risk of similar deadlocks.
We now solve this by passing a buffer queue along with all upcalls where
sk_lock.slock may potentially be held. Response or rejected message
buffers are accumulated into this queue instead of being sent out
directly, and only sent once we know we are safely outside the slock
context.

The inline isa_register_driver stub simply allows compilation on systems
with CONFIG_ISA disabled; the dummy isa_register_driver does not
register an isa_driver at all. The inline isa_register_driver should
return -ENODEV to indicate lack of support when attempting to register
an isa_driver on such a system with CONFIG_ISA disabled.

The isa_bus_init function must be called before drivers which utilize
the ISA bus driver are registered. A race condition for initilization
exists if device_initcall is used (the isa_bus_init callback is placed
in the same initcall level as dependent drivers which use module_init).
This patch ensures that isa_bus_init is called first by utilizing
postcore_initcall in favor of device_initcall.

With the introduction of the ISA_BUS_API Kconfig option, ISA-style
drivers may be built for X86_64 architectures. This patch changes the
ISA Kconfig option dependency of the WinSystems EBC-C384 watchdog timer
driver to ISA_BUS_API, thus allowing it to build for X86_64 as it is
expected to.

Several modern devices, such as PC/104 cards, are expected to run on
modern systems via an ISA bus interface. Since ISA is a legacy interface
for most modern architectures, ISA support should remain disabled in
general. Support for ISA-style drivers should be enabled on a per driver
basis.
To allow ISA-style drivers on modern systems, this patch introduces the
ISA_BUS_API and ISA_BUS Kconfig options. The ISA bus driver will now
build conditionally on the ISA_BUS_API Kconfig option, which defaults to
the legacy ISA Kconfig option. The ISA_BUS Kconfig option allows the
ISA_BUS_API Kconfig option to be selected on architectures which do not
enable ISA (e.g. X86_64).
The ISA_BUS Kconfig option is currently only implemented for X86
architectures. Other architectures may have their own ISA_BUS Kconfig
options added as required.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are rather small patches but fixing several outstanding bugs in
nf_conntrack and nf_tables, as well as minor problems with missing
SYNPROXY header uapi installation:
1) Oneliner not to leak conntrack kmemcache on module removal, this
problem was introduced in the previous merge window, patch from
Florian Westphal.
2) Two fixes for insufficient ruleset loop validation, one due to
incorrect flag check in nf_tables_bind_set() and another related to
silly wrong generation mask logic from the walk path, from Liping
Zhang.
3) Fix double-free of anonymous sets on error, this fix simplifies the
code to let the abort path take care of releasing the set object,
also from Liping Zhang.
4) The introduction of helper function for transactions broke the skip
inactive rules logic from the nft_do_chain(), again from Liping
Zhang.
5) Two patches to install uapi xt_SYNPROXY.h header and calm down
kbuild robot due to missing #include <linux/types.h>.

It's annoying to constantly see the same "Not yet implemented" message
over and over with nothing able to be done about it, so rate limit it
for now to keep user's logs "clean".

Swapping a cable from a "Mgmt Allowed=No" switch port to a
"Mgmt Allowed=Yes" switch port doesn't send a pkey change
notification. Therefore, the link doesn't become active as
the oib_utils layer uses an old pkey table cache.
Fix by ensuring the pkey change notification is sent when
the table is changed both explicitly by the FM and implicitly
by the driver via a cable swap.

FULL_MGMT_P_KEY doesn't get cleared from the pkey table at link bounce
because the link down and link bounce code paths are different when
moving a QSFP cable on a switch. This causes an HFI unit connected to a
switch to try to be initialized to an FM node when the QSFP cable is
moved from a MgmtAllowed=NO port to a MgmtAllowed=YES port and back to a
MgmtAllowed=NO port. Remove FULL_MGMT_P_KEY from pkey table at link up.
