disabled
Since commit f2c3c67f00 (merge commit that adds commit "ARM: mvebu:
completely disable hardware I/O coherency"), we disable I/O coherency
on Armada EBU platforms.
However, we continue to initialize the coherency fabric, because this
coherency fabric is needed on Armada XP for inter-CPU
coherency. Unfortunately, due to this, we also continued to execute
the coherency fabric initialization code for Armada 375/38x, which
switched the PL310 into I/O coherent mode. This has the effect of
disabling the outer cache sync operation: this is needed when I/O
coherency is enabled to work around a PCIe/L2 deadlock. But obviously,
when I/O coherency is disabled, having the outer cache sync operation
is crucial.
Therefore, this commit fixes the armada_375_380_coherency_init() so
that the PL310 is switched to I/O coherent mode only if I/O coherency
is enabled.
Without this fix, all devices using DMA are broken on Armada 375/38x.

Allwinner fixes for 3.19
A few minor fixes for the 3.19 kernel:
- The 8250 uart driver now respects the aliases, which pointed out that we
were using them wrong. Fixed them.
- The simplefb pipeline that was used on the A10 caused flickering and
tearing, and rendered it pretty much useless. Added a new simplefb node
with another pipeline that removes this issue. Note that we need to keep
the old node because u-boot 2015.01 uses it.

Testing has shown that on sun4i the display backend engine does not have
deep enough fifo-s causing flickering / tearing in full-hd mode due to
fifo underruns. This can be avoided by letting the display frontend engine
do the dma from memory, and then letting it feed the data directly into
the backend unmodified, as the frontend does have deep enough fifo-s.
Note since u-boot-v2015.01 has been released using the de_be0-lcd0-hdmi
pipeline on sun4i, we need to keep that one around too (unfortunately).

Currently PWM functionality is broken on mx25 due to the wrong assignment of the
PWM "per" clock.
According to Documentation/devicetree/bindings/clock/imx25-clock.txt:
pwm_ipg_per 52
,so update the pwm "per" to use 'pwm_ipg_per' instead of 'per10' clock.
With this change PWM can work fine on mx25.

Merge "Urgent omap4 legacy interrupt regression fix for v3.19-rc series" from
Tony Lindgren:
A rather urgent pull request to fix omap4 legacy interrupts.
The legacy interrupts on omap4 got broken when gic got changed to
use irq_domain_add_linear() instead of the irq_domain_add_legacy(). We
still have the hardcoded legacy IRQ numbers in use in several places,
most notably the in the legacy DMA. It took a while to figure out
what the problem was and how it should be fixed for the -rc series.
Also include is a regression fix for the dra7 dwc3 suspend.

On Armada XP, 375 and 38x the MBus window 13 has the remap capability,
like windows 0 to 7. However, the mvebu-mbus driver isn't currently
taking into account this special case, which means that when window 13
is actually used, the remap registers are left to 0, making the device
using this MBus window unavailable.
As a minimal fix for stable, don't use window 13. A full fix will
follow later.

The current hardware I/O coherency is known to cause problems with DMA
coherent buffers, as it still requires explicit I/O synchronization
barriers, which is not compatible with the semantics expected by the
Linux DMA coherent buffers API.
So, in order to have enough time to validate a new solution based on
automatic I/O synchronization barriers, this commit disables hardware
I/O coherency entirely. Future patches will re-enable it.

Commit 9a1091ef0017 ("irqchip: gic: Support hierarchy irq domain")
changed the GIC driver to use a non-legacy IRQ domain on DT
platforms. This patch assumes that DT-driven systems are getting
all of their interrupts from device tree.
Turns out that OMAP has quite a few hidden gems, and still uses
hardcoded interrupts despite having fairly complete DTs.
This patch attempts to work around these by offering a translation
method that can be called directly from the hwmod code, if present.
The same hack is sprinkled over PRCM and TWL.
It isn't pretty, but it seems to do the job without having to add
more hacks to the interrupt controller code.
Tested on OMAP4 (Panda-ES) and OMAP5 (UEVM5432).

rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux
settings depending on the card state. This collides with a lot of assumptions.
It only works when using the internal card-detect mechanism and breaks
horribly when using either the normal card-detect via the slot-gpio function
or via any other pin. Also there is of course no link between the mmc and jtag
on the software-side, so the jtag clocks may very well be disabled when the
card is ejected and the soc switches back to the jtag pinmux.
Leaving the switching function enabled did result in mmc timeouts and rcu
stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases,
as we expect the devicetree to explicitly select either mmc or jtag pinmuxes
anyway.

Reason: The PIOE2 pin is connected to the NAND_Tree# of KSZ8081,
But it outputs LOW during the reset period, which cause the NAND_Tree# enabled.

Fix for BUG_ON(anon_vma->degree) splashes in unlink_anon_vmas() ("kernel
BUG at mm/rmap.c:399!") caused by commit 7a3ef208e662 ("mm: prevent
endless growth of anon_vma hierarchy")
Anon_vma_clone() is usually called for a copy of source vma in
destination argument. If source vma has anon_vma it should be already
in dst->anon_vma. NULL in dst->anon_vma is used as a sign that it's
called from anon_vma_fork(). In this case anon_vma_clone() finds
anon_vma for reusing.
Vma_adjust() calls it differently and this breaks anon_vma reusing
logic: anon_vma_clone() links vma to old anon_vma and updates degree
counters but vma_adjust() overrides vma->anon_vma right after that. As
a result final unlink_anon_vmas() decrements degree for wrong anon_vma.
This patch assigns ->anon_vma before calling anon_vma_clone().

Commit fee7e49d4514 ("mm: propagate error from stack expansion even for
guard page") made sure that we return the error properly for stack
growth conditions. It also theorized that counting the guard page
towards the stack limit might break something, but also said "Let's see
if anybody notices".
Somebody did notice. Apparently android-x86 sets the stack limit very
close to the limit indeed, and including the guard page in the rlimit
check causes the android 'zygote' process problems.
So this adds the (fairly trivial) code to make the stack rlimit check be
against the actual real stack size, rather than the size of the vma that
includes the guard page.

couple of weeks of fixes,
Two sets of amdkfd fixes, this is a new feature this kernel, and this

kernel and also the iommu vs gpu ordering patch, it also reworks the
ioctl before the initial release.
Otherwise:
- radeon: some misc fixes all over, hdmi, 4k, dpm
- nouveau: mcp77 init fixes, oops fix, bug on fix, msi fix
- i915: power fixes, revert VGACNTR patch
Probably be quiteer next week since I'll be at LCA anyways"
