Hi Linus,
Please pull these two arm64 fixes for -rc6. We've got a regression fix for
the signal raised when userspace makes an unsupported unaligned access and a
revert of the contiguous (hugepte) support for hugetlb, which has once again
been found to be broken. One day, maybe, we'll get it right

On x86, 5-level paging enables 56-bit userspace virtual address space.
Not all user space is ready to handle wide addresses. It's known that
at least some JIT compilers use higher bits in pointers to encode their
information. It collides with valid pointers with 5-level paging and
leads to crashes.

In current code the output logs are not well symmetric for sink and link
enabling and disabling. This patch is to fix that so can output paired
logs.

This series add several fixes to STM32 pinctrl:
- Set input mode when PIN is used as interrupt
- Implement .get_direction() gpio_chip callback
- In DT: set each gpio controller as a interrupt controller. User who
wants to use gpio as interrupt will have choice to use either "gpiolib"
int
Pinctrl has to be registered earlier. Mainly to register bank irqdomain
earlier as other devices could use interrupts from those irqdomain.

Tested against the 4.11-rc1 OpenCSD perf tree - reproduced the problem
and confirmed the patch fixes it on Juno r1.
Noted that the command line
./perf record -e cs_etm/@2001.etf/ uname
also causes the same problem,
Larger question that may need future investigation in the openCSD

Given your update to 3/5, I suspect that we could live with it. I am
expecting some complaints about increases in idle-entry latency, but might
be best to wait for complaints rather than

Hi,
here is a small patch-set for the omap-iommu driver to make
it use new features of the iommu-core. Please review.
Thanks,

Changes since v1:
* Dropped patch 2 and moved device-link and

Maybe someone should propose a micro-conf at Linux Plumbers where we
can brain storm a way to re-invent printk()? Seems it can do with a
completely new rewrite. ;-)

ATS is broken on this hardware and causes IOMMU stalls and
system failure. Disable ATS on these devices to make them
usable again with IOMMU enabled.
Note that the commit in the Fixes-tag is not buggy, it
just uncovers the problem in the hardware by increasing

The hardware has a LPI interrupt.
There is already code in the stmmac driver to parse and handle the
interrupt. However, this information was missing from the DT binding.
