 will move to the new LVDS DT bindings. I thus propose merging these three
 patches in v4.17 already to fix the problem as this is the simplest
 solution."

b2d6cee117 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
The bpf syscall and selftests conflicts were trivial
overlapping changes.

The r8169 change involved moving the added mdelay from 'net' into a
different function.

A TLS close bug fix overlapped with the splitting of the TLS state
into separate TX and RX parts.  I just expanded the tests in the bug
fix from "ctx->conf == X" into "ctx->tx_conf == X && ctx->rx_conf
== X".

09230cbc1b swiotlb: move the SWIOTLB config symbol to lib/Kconfig
This way we have one central definition of it, and user can select it as
needed.  The new option is not user visible, which is the behavior
it had in most architectures, with a few notable exceptions:

 - On x86_64 and mips/loongson3 it used to be user selectable, but
   defaulted to y.  It now is unconditional, which seems like the right
   thing for 64-bit architectures without guaranteed availablity of
   IOMMUs.
 - on powerpc the symbol is user selectable and defaults to n, but
   many boards select it.  This change assumes no working setup
   required a manual selection, but if that turned out to be wrong
   we'll have to add another select statement or two for the respective
   boards.

Define this symbol if the architecture either uses 64-bit pointers or the
PHYS_ADDR_T_64BIT is set.  This covers 95% of the old arch magic.  We only
need an additional select for Xen on ARM (why anyway?), and we now always
set ARCH_DMA_ADDR_T_64BIT on mips boards with 64-bit physical addressing

15b28bbcd5 dma-debug: move initialization to common code
Most mainstream architectures are using 65536 entries, so lets stick to
that.  If someone is really desperate to override it that can still be
done through <asm/dma-mapping.h>, but I'd rather see a really good
rationale for that.

dma_debug_init is now called as a core_initcall, which for many
architectures means much earlier, and provides dma-debug functionality
earlier in the boot process.  This should be safe as it only relies
on the memory allocator already being available.

Commit 4c9a27a6c66d ("ARM: tegra: Fix ULPI regression on Tegra20") changed
"ulpi-link" clock from CDEV2 to PLL_P_OUT4. Turned out that PLL_P_OUT4 is
the parent of CDEV2 clock and original clock setup of "ulpi-link" was
correct. The reverted patch was fixing USB for one board and broke the
other, now Tegra's clk driver correctly sets parent for the CDEV2 clock
and hence patch could be reverted safely, restoring USB for all of the
boards.

647efef69d ARM: dts: correct missing "compatible" entry for ti81xx SoCs
The missing "compatible" entries are needed by drivers/clk/ti/clkctrl.c,
and without them the structures initialized in drivers/clk/ti/clk-814x.c
are not passed to configuration code. The result is a "not found from
clkctrl data" error message, although boot proceeds anyway.

The reason why the compatible is not found is because the board specific
files override the SoC compatible without including it. This did not
cause any issues until with the clkctrl nodes got introduced.

Very lightly tested on a (lurching) AM3874 design that's in the middle
of a kernel upgrade from TI's abandoned 2.6.37 tree.

Also tested on j5eco-evm and hp-t410 to verify the clkctrl clocks are
found.

Since commit 80ac93c27441 ("gpio: omap: Fix lost edge interrupts") this

handle_simmple_irq() which doesn't touch the hardware.

Add single ACK operation per each active IRQ pin to the handler. While

also called only once for each active IRQ pin.

9411ac07cd ARM: davinci: fix GPIO lookup for I2C
The GPIO chip is called davinci_gpio.0 in legacy mode. Fix it, so that
I2C can correctly lookup the recovery gpios.

Note that it is the gpio-davinci driver that sets the gpiochip label to
davinci_gpio.0.

Also, the I2C device uses an id of 1 on DM644x and DM355.

While at it, convert to using GPIO_TO_PIN() for referring to GPIO pin
numbers, like it is done in rest of the board support files.

3eb0f5193b signal: Ensure every siginfo we send has all bits initialized
Call clear_siginfo to ensure every stack allocated siginfo is properly
initialized before being passed to the signal sending functions.

Note: It is not safe to depend on C initializers to initialize struct
siginfo on the stack because C is allowed to skip holes when
initializing a structure.

The initialization of struct siginfo in tracehook_report_syscall_exit
was moved from the helper user_single_step_siginfo into
tracehook_report_syscall_exit itself, to make it clear that the local
variable siginfo gets fully initialized.

In a few cases the scope of struct siginfo has been reduced to make it
clear that siginfo siginfo is not used on other paths in the function
in which it is declared.

Instances of using memset to initialize siginfo have been replaced
with calls clear_siginfo for clarity.
