Pull xen fixes from Juergen Gross:
- a fix for the Xen gntdev device repairing an issue in case of partial
failure of mapping multiple pages of another domain
- a fix of a regression in the Xen balloon driver introduced in 4.13
- a build fix for Xen on ARM which will trigger e.g. for Linux RT
- a maintainers update for pvops (not really Xen, but carrying through
this tree just for convenience)

rwlock.h should not be included directly. Instead linux/splinlock.h
should be included. One thing it does is to break the RT build.

The commit afece3ab9a36 ("PM / Domains: Add time accounting to various
genpd states") causes a boot regression for ux500.
The problem occurs when the ux500 machine code calls pm_genpd_init(), which
since the above change triggers a call to ktime_get(). More precisely,
because ux500 initializes PM domains in the init_IRQ() phase of the boot,
timekeeping has not yet been initialized.
Fix the problem by moving the initialization of the PM domains to after
timekeeping has been initialized.

case this is the peripheral clock (PCLK), so explicitly

According to i.MX7D reference manual (Rev. 0.1, table 7-1, page 1221)
legacy PCI interrupt mapping is as follows:
- PCIE INT A is IRQ 122
- PCIE INT B is IRQ 123
- PCIE INT C is IRQ 124
- PCIE INT D is IRQ 125
Invert the mapping information in corresponding DT node to reflect
that.

By default sparse uses the characteristics of the build
machine to infer things like the wordsize.
This is fine when doing native builds but for ARM it's,
I suspect, very rarely the case and if the build are done
on a 64bit machine we get a bunch of warnings like:
'cast truncates bits from constant value (... becomes ...)'
Fix this by adding the -m32 flags for sparse.

Some nommu systems have RAM at address 0. When vectors are not located
there, the very beginning of memory remains available for dynamic
allocations. The memblock allocator explicitly skips the first page
but the standard page allocator does not, and while it correctly returns
a non-null struct page pointer for that page, page_address() gives 0
which gets confused with NULL (out of memory) by callers despite having
plenty of free memory left.

Contrary to other RPi devices, RPi3 uses uart0 to communicate with
the BCM43438 bluetooth controller. uart1 is then used for the console.
Today, the console configuration is inherited from the bcm283x dtsi
(bootargs) which is not the correct one for the RPi3. This leads to
routing issue and confuses the Bluetooth controller with unexpected
data.
This patch introduces chosen/stdout path to configure console to uart0
on bcm283x family and overwrite it to uart1 in the RPi3 dts.
Create serial0/1 aliases referring to uart0 and uart1 paths.
Remove unneeded earlyprintk.

STM32 fixes for v4.14:

-Use right compatible for stm32f469 pinctrl. It implies to use

Currently, same stm32f429-pinctrl driver is used for stm32f429 and
stm32f469. As pin map is different between those 2 MCUs,
a stm32f469-pinctrl driver has been recently added.
This patch
-allows to use stm32f469-pinctrl driver for stm32f469 boards
-reworks stm32 devicetree files to fit with stm32f429 / stm32f469
In the same time it fixes an issue when only MACH_STM32F469 flag is
selected in menuconfig.

To declare gpio interrupt line for STMPE1600, 2 possibilities are offered:
-use gpio binding (and then the gpiolib interface inside driver)
-use interrupt binding as each gpio-controller are also interrupt controller
on stm32f429.
In STMPE 1600 node both (gpio and interrupt) bindings are defined.
This patch fixes this issue and use only interrupt binding.

(errata FE-8471889).
i2c-mv64xxx driver handles this errata based on the compatible string
"marvell,mv78230-a0-i2c".

Disable the generic address limit check in favor of an architecture
specific optimized implementation. The generic implementation using
pending work flags did not work well with ARM and alignment faults.
The address limit is checked on each syscall return path to user-mode
path as well as the irq user-mode return function. If the address limit
was changed, a function is called to report data corruption (stopping
the kernel or process based on configuration).
The address limit check has to be done before any pending work because
they can reset the address limit and the process is killed using a
SIGKILL signal. For example the lkdtm address limit check does not work
because the signal to kill the process will reset the user-mode address
limit.

This reverts commit 73ac5d6a2b6ac3ae8d1e1818f3e9946f97489bc9.
The work pending loop can call set_fs after addr_limit_user_check
removed the _TIF_FSCHECK flag. This may happen at anytime based on how
ARM handles alignment exceptions. It leads to an infinite loop condition.
After discussion, it has been agreed that the generic approach is not
tailored to the ARM architecture and any fix might not be complete. This
patch will be replaced by an architecture specific implementation. The
work flag approach will be kept for other architectures.

When the second display pipeline device nodes for the A31/A31s were
added, it was not known that the TCONs could (through either DRCs)
select either backend as their input. Thus in the endpoints connecting
these components together, the endpoint IDs were set to 0, while in
fact they should have been set to 1.
