Pull more powerpc updates from Michael Ellerman:
"The change to the Linux page table geometry was delayed for more
testing with 16G pages, and there's the new CPU features stuff which
just needed one more polish before going in. Plus a few changes from
Scott which came in a bit late. And then various fixes, mostly minor.
Summary highlights:
- rework the Linux page table geometry to lower memory usage on
64-bit Book3S (IBM chips) using the Hash MMU.
- support for a new device tree binding for discovering CPU features
on future firmwares.
- Freescale updates from Scott:
"Includes a fix for a powerpc/next mm regression on 64e, a fix for
a kernel hang on 64e when using a debugger inside a relocated
kernel, a qman fix, and misc qe improvements."
Thanks to: Christophe Leroy, Gavin Shan, Horia Geantă, LiuHailong,
Nicholas Piggin, Roy Pledge, Scott Wood, Valentin Longchamp"

Pull hw lockdown support from David Howells:
"Annotation of module parameters that configure hardware resources
including ioports, iomem addresses, irq lines and dma channels.
This allows a future patch to prohibit the use of such module
parameters to prevent that hardware from being abused to gain access
to the running kernel image as part of locking the kernel down under
UEFI secure boot conditions.
Annotations are made by changing:
module_param(n, t, p)
module_param_named(n, v, t, p)
module_param_array(n, t, m, p)
to:
module_param_hw(n, t, hwtype, p)
module_param_hw_named(n, v, t, hwtype, p)
module_param_hw_array(n, t, hwtype, m, p)
where the module parameter refers to a hardware setting
hwtype specifies the type of the resource being configured. This can
be one of:
ioport Module parameter configures an I/O port
iomem Module parameter configures an I/O mem address
ioport_or_iomem Module parameter could be either (runtime set)
irq Module parameter configures an I/O port
dma Module parameter configures a DMA channel
dma_addr Module parameter configures a DMA buffer address
other Module parameter configures some other value
Note that the hwtype is compile checked, but not currently stored (the
lockdown code probably won't require it). It is, however, there for
future use.
A bonus is that the hwtype can also be used for grepping.
The intention is for the kernel to ignore or reject attempts to set
annotated module parameters if lockdown is enabled. This applies to
options passed on the boot command line, passed to insmod/modprobe or
direct twiddling in /sys/module/ parameter files.
The module initialisation then needs to handle the parameter not being
set, by (1) giving an error, (2) probing for a value or (3) using a
reasonable default.
What I can't do is just reject a module out of hand because it may
take a hardware setting in the module parameters. Some important
modules, some ipmi stuff for instance, both probe for hardware and
allow hardware to be manually specified; if the driver is aborts with
any error, you don't get any ipmi hardware.
Further, trying to do this entirely in the module initialisation code
doesn't protect against sysfs twiddling.
[!] Note that in and of itself, this series of patches should have no
effect on the the size of the kernel or code execution - that is
left to a patch in the next series to effect. It does mark
annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in
an already existing field"

Pull clk updates from Stephen Boyd:
"Sort of on the quieter side this time, which is probably due more to
me not catching up as quickly on patch review than anything else.
Overall it seems normal though, a few small changes to the core,
mostly small non-critical fixes here and there as well as driver
updates for new and existing hardware support.
The biggest things are the TI clk driver rework to lay the groundwork
for clkctrl support in the next merge window and the AmLogic
audio/graphics clk support.
Core:
- clk_possible_parents debugfs file so we know which parents a clk
could possibly have
- Fix to make clk rate change notifiers stop on the first failure
instead of continuing
New Drivers:
- Mediatek MT6797 SoCs
- hi655x PMIC clks
- AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks
- Allwinner H5 SoCs and PRCM hardware
Updates:
- Nvidia Tegra T210 cleanups and non-critical fixes
- TI OMAP cleanups in preparation for clkctrl support
- trivial fixes like kcalloc(), devm_* conversions, and seq_puts()
- ZTE zx296718 SoC VGA clks
- Rockchip clk-ids, fixups, and rename of rk1108 to rv1108
- IDT VersaClock 5P49V5935 support
- Renesas R-Car H3 and M3-W IMR clks and ES2.0 rev of R-Car H3

Pull TEE driver infrastructure and OP-TEE drivers from Arnd Bergmann:
"This introduces a generic TEE framework in the kernel, to handle
trusted environemtns (security coprocessor or software implementations
such as OP-TEE/TrustZone). I'm sending it separately from the other
arm-soc driver changes to give it a little more visibility, once the
subsystem is merged, we will likely keep this in the arm₋soc drivers
branch or have the maintainers submit pull requests directly,
depending on the patch volume.
I have reviewed earlier versions in the past, and have reviewed the
latest version in person during Linaro Connect BUD17.
Here is my overall assessment of the subsystem:
- There is clearly demand for this, both for the generic
infrastructure and the specific OP-TEE implementation.
- The code has gone through a large number of reviews, and the review
comments have all been addressed, but the reviews were not coming
up with serious issues any more and nobody volunteered to vouch for
the quality.
- The user space ioctl interface is sufficient to work with the
OP-TEE driver, and it should in principle work with other TEE
implementations that follow the GlobalPlatform[1] standards, but it
might need to be extended in minor ways depending on specific
requirements of future TEE implementations
- The main downside of the API to me is how the user space is tied to
the TEE implementation in hardware or firmware, but uses a generic
way to communicate with it. This seems to be an inherent problem
with what it is trying to do, and I could not come up with any
better solution than what is implemented here.

Pull ceph updates from Ilya Dryomov:
"The two main items are support for disabling automatic rbd exclusive
lock transfers from myself and the long awaited -ENOSPC handling
series from Jeff.
The former will allow rbd users to take advantage of exclusive lock's
built-in blacklist/break-lock functionality while staying in control
of who owns the lock. With the latter in place, we will abort
filesystem writes on -ENOSPC instead of having them block
indefinitely.
Beyond that we've got the usual pile of filesystem fixes from Zheng,
some refcount_t conversion patches from Elena and a patch for an
ancient open() flags handling bug from Alexander"

Under SRIOV resource management, extra counters are allocated to VFs
from a free pool. If that pool is empty, the ALLOC_RES command for
a counter resource fails -- and this generates a misleading error
message in the message log.
Under SRIOV, each VF is allocated (i.e., guaranteed) 2 counters --
one counter per port. For ETH ports, the RoCE driver requests an
additional counter (above the guaranteed counters). If that request
fails, the VF RoCE driver simply uses the default (i.e., guaranteed)
counter for that port.
Thus, failing to allocate an additional counter does not constitute
a problem, and the error message on the PF when this occurs should
be reduced to debug level.
Finally, to identify the situation that the reason for the failure is
that no resources are available to grant to the VF, we modified the
error returned by mlx4_grant_resource to -EDQUOT (Quota exceeded),
which more accurately describes the error.

stragllers that came in late last week. I took them because it allowed
me to legitimately claim that the RDMA patchworks queue was, for a
short time, 100% cleared of all waiting kernel patches, woohoo! :-).
I have it under my for-next tag, so it did get 0day and linux- next
over the end of last week, and linux-next did show one minor conflict.
Summary:
'for-linus' tag:
- mlx5/IPoIB fixup patch
'for-next' tag:
- the hfi1 15 patch set that landed late
- IPoIB get_link_ksettings which landed late because I asked for a
respin
- one late rxe change
- one -rc worthy fix that's in early"

Nandsim has own functions set_memalloc() and clear_memalloc() for robust
setting and clearing of PF_MEMALLOC. Replace them by the new generic
helpers. No functional change.
