This tag contains the following fixes on top of v4.8-rc1:
- ITS init issues

At imx6ul_init_machine, it calls imx6ul_pm_init which needs to find
platform device for ocram, but the default populate platform device is at
of_platform_default_populate_init, which is located at arch_initcall_sync,
and called later than arch_initcall (.init_machine is located at that).
So below warning message will be showed during boots up:
imx6q_suspend_init: failed to find ocram device!
imx6_pm_common_init: No DDR LPM support with suspend -19!
Due to lack of ocram device, the suspend mode "mem" which needs ocram to
store suspend routine code is invalid.
This commit populates platform device before imx6ul_pm_init like other
imx6 platforms do, and the suspend mode "mem" can work successfully.

When converting a gfn to a pfn, we call gfn_to_pfn_prot, which returns
various kinds of error values. It turns out that is_error_pfn() only
returns true when the gfn was found in a memory slot and could somehow
not be used, but it does not return true if the gfn does not belong to
any memory slot.
Change use to is_error_noslot_pfn() which covers both cases.
Note: Since we already check for kvm_is_error_hva(hva) explicitly in the
caller of this function while holding the kvm->srcu lock protecting the
memory slots, this should never be a problem, but nevertheless this
change is warranted as it shows the intention of the code.

KVM devices were manipulating list data structures without any form of
synchronization, and some implementations of the create operations also
suffered from a lack of synchronization.
Now when we've split the xics create operation into create and init, we
can hold the kvm->lock mutex while calling the create operation and when
manipulating the devices list.
The error path in the generic code gets slightly ugly because we have to
take the mutex again and delete the device from the list, but holding
the mutex during anon_inode_getfd or releasing/locking the mutex in the
common non-error path seemed wrong.

getting mach-shmobile to build again with SMP disabled
- A fix for a realview regression that broke real hardware but
not the qemu model that everyone uses in practice (needed

Clearly QEMU is very permissive in how its PL310 model may be set up,
but the real hardware turns out to be far more particular about things
actually being correct. Fix up the DT description so that the real
thing actually boots:
- The arm,data-latency and arm,tag-latency properties need 3 cells to
be valid, otherwise we end up retaining the default 8-cycle latencies
which leads pretty quickly to lockup.
- The arm,dirty-latency property is only relevant to L210/L220, so get
rid of it.
- The cache geometry override also leads to lockup and/or general
misbehaviour. Irritatingly, the manual doesn't state the actual PL310
configuration, but based on the boardfile code and poking registers
from the Boot Monitor, it would seem to be 8 sets of 16KB ways.
With that, we can successfully boot to enjoy the fun of mismatched FPUs...

The crash is due to the fact that the UEFI page tables are not owned by
init_mm, but are not covered by fully constructed struct pages.
Given that the UEFI subsystem is currently the only user of
create_mapping_late(), add an unconditional call to pgtable_page_ctor() to
late_alloc().

To limit the amount of mapped low memory, we determine a physical address
boundary based on the start of the vmalloc area using __pa().
Strictly speaking, the vmalloc area location is arbitrary and does not
necessarily corresponds to a valid physical address. For example, if
PAGE_OFFSET = 0x80000000
PHYS_OFFSET = 0x90000000
vmalloc_min = 0xf0000000
then __pa(vmalloc_min) overflows and returns a wrapped 0 when phys_addr_t
is a 32-bit type. Then the code that follows determines that the entire
physical memory is above that boundary and no low memory gets mapped at
all:
|[...]
|Machine model: Freescale i.MX51 NA04 Board
|Ignoring RAM at 0x90000000-0xb0000000 (!CONFIG_HIGHMEM)
|Consider using a HIGHMEM enabled kernel.
To avoid this problem let's make vmalloc_limit a 64-bit value all the
time and determine that boundary explicitly without using __pa().

Currently, the ports as seen from the rear number as:
eth0 sfp lan5 lan4 lan3 lan2 lan1 lan6
which is illogical - this came about because the rev 2.0 boards have the
LEDs on the front for the DSA switch (lan5-1) reversed. Rev 2.1 boards
fixed the LED issue, and the Clearfog case numbers the lan ports
increasing from left to right.
Maintaining this illogical numbering causes confusion, with reports that
"my link isn't coming up" and "my connection negotiates 10base-Half"
both of which are due to people thinking that the port next to the SFP
is lan1.
Fix this by renumbering the ports to match people's expectations.

The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

The patch that this was preparing for made it into neither v4.7 nor

The ugly bit is the conflicts. A couple of them are simple conflicts due
to 4.7 fixes, but most of them are with other trees. There was definitely
too much reliance on Acked-by here. Some conflicts are for KVM patches
where _I_ gave my Acked-by, but the worst are for this pull request's
patches that touch files outside arch/*/kvm. KVM submaintainers should
probably learn to synchronize better with arch maintainers, with the
latter providing topic branches whenever possible instead of Acked-by.
This is what we do with arch/x86. And I should learn to refuse pull
requests when linux-next sends scary signals, even if that means that
submaintainers have to rebase their branches.
Anyhow, here's the list:
- arch/x86/kvm/vmx.c: handle_pcommit and EXIT_REASON_PCOMMIT was removed
by the nvdimm tree. This tree adds handle_preemption_timer and
EXIT_REASON_PREEMPTION_TIMER at the same place. In general all mentions
of pcommit have to go.
There is also a conflict between a stable fix and this patch, where the
stable fix removed the vmx_create_pml_buffer function and its call.
- virt/kvm/kvm_main.c: kvm_cpu_notifier was removed by the hotplug tree.
This tree adds kvm_io_bus_get_dev at the same place.
- virt/kvm/arm/vgic.c: a few final bugfixes went into 4.7 before the
file was completely removed for 4.8.
- include/linux/irqchip/arm-gic-v3.h: this one is entirely our fault;
this is a change that should have gone in through the irqchip tree and
pulled by kvm-arm. I think I would have rejected this kvm-arm pull
request. The KVM version is the right one, except that it lacks
GITS_BASER_PAGES_SHIFT.
- arch/powerpc: what a mess. For the idle_book3s.S conflict, the KVM
tree is the right one; everything else is trivial. In this case I am
not quite sure what went wrong. The commit that is causing the mess
(fd7bacbca4, "KVM: PPC: Book3S HV: Fix TB corruption in guest exit
path on HMI interrupt", 2016-05-15) touches both arch/powerpc/kernel/
and arch/powerpc/kvm/. It's large, but at 396 insertions/5 deletions
I guessed that it wasn't really possible to split it and that the 5
deletions wouldn't conflict. That wasn't the case.
- arch/s390: also messy. First is hypfs_diag.c where the KVM tree
moved some code and the s390 tree patched it. You have to reapply the
relevant part of commits 6c22c98637, plus all of e030c1125e, to
arch/s390/kernel/diag.c. Or pick the linux-next conflict
resolution from http://marc.info/?l=kvm&m=146717549531603&w=2.
Second, there is a conflict in gmap.c between a stable fix and 4.8.
The KVM version here is the correct one.
I have pushed my resolution at refs/heads/merge-20160802 (commit
3d1f53419842) at git://git.kernel.org/pub/scm/virt/kvm/kvm.git.

For rcar-gen2, we build the SMP files even for UP configurations,
and that just broke:
arch/arm/mach-shmobile/built-in.o: In function `shmobile_smp_init_fallback_ops':
pm-rcar-gen2.c:(.init.text+0x40c): undefined reference to `platform_can_secondary_boot'
This adds an compile-time check before the call to platform_can_secondary_boot,
turning the function into an empty stub for UP configurations.

time around, some of the contents worth pointing out is:
- New SoC platforms:

- Broadcom BCM23550
- Cirrus Logic EP7209 and EP7211 (clps711x platforms)_
- Hisilicon HI3519

Some of the other delta that is sticking out, line-count wise:
- Exynos moves of IP blocks under an SoC bus, which causes a large delta due
to indentation changes
- A new Tegra K1 board: Apalis
- A bunch of small updates to many Allwinner platforms; new hardware support,
some cleanup, etc.

A quiet regulator API release, a few new drivers and some fixes but
nothing too notable. There will also be some updates for the PWM
regulator coming through the PWM tree which provide much smoother
operation when taking over an already running PWM regulator after boot
using some new PWM APIs.
- Support for configuration of the initial suspend state from DT.
- New drivers for Mediatek MT6323, Ricoh RN5T567 and X-Powers AXP809.

This updates the generic and arch specific implementation to return true
if we need to do a tlb flush. That means if a __tlb_remove_page
indicate a flush is needed, the page we try to remove need to be tracked
and added again after the flush. We need to track it because we have
already update the pte to none and we can't just loop back.
This change is done to enable us to do a tlb_flush when we try to flush
a range that consists of different page sizes. For architectures like
ppc64, we can do a range based tlb flush and we need to track page size
for that. When we try to remove a huge page, we will force a tlb flush
and starts a new mmu gather.

__GFP_REPEAT has a rather weak semantic but since it has been introduced
around 2.6.12 it has been ignored for low order allocations.
PGALLOC_GFP uses __GFP_REPEAT but none of the allocation which uses this
flag is for more than order-2. This means that this flag has never been
actually useful here because it has always been used only for
PAGE_ALLOC_COSTLY requests.

Pull perf updates from Ingo Molnar:
"With over 300 commits it's been a busy cycle - with most of the work
concentrated on the tooling side (as it should).
The main kernel side enhancements were:
- Add per event callchain limit: Recently we introduced a sysctl to
tune the max-stack for all events for which callchains were
requested:
$ sysctl kernel.perf_event_max_stack
kernel.perf_event_max_stack = 127
Now this patch introduces a way to configure this per event, i.e.
this becomes possible:
$ perf record -e sched:*/max-stack=2/ -e block:*/max-stack=10/ -a
allowing finer tuning of how much buffer space callchains use.
This uses an u16 from the reserved space at the end, leaving
another u16 for future use.
There has been interest in even finer tuning, namely to control the
max stack for kernel and userspace callchains separately. Further
discussion is needed, we may for instance use the remaining u16 for
that and when it is present, assume that the sample_max_stack
introduced in this patch applies for the kernel, and the u16 left
is used for limiting the userspace callchain (Arnaldo Carvalho de
Melo)
- Optimize AUX event (hardware assisted side-band event) delivery

work) (Dave Hansen)
- Refine and fix Intel LBR support (David Carrillo-Cisneros)
- Add support for Intel 'TopDown' events (Andi Kleen)
- Intel uncore PMU driver fixes and enhancements (Kan Liang)
- ... other misc changes.
Here's an incomplete list of the tooling enhancements (but there's
much more, see the shortlog and the git log for details):
- Support cross unwinding, i.e. collecting '--call-graph dwarf'
perf.data files in one machine and then doing analysis in another
machine of a different hardware architecture. This enables, for
instance, to do:
$ perf record -a --call-graph dwarf
on a x86-32 or aarch64 system and then do 'perf report' on it on a
x86_64 workstation (He Kuang)
- Allow reading from a backward ring buffer (one setup via
sys_perf_event_open() with perf_event_attr.write_backward = 1)
(Wang Nan)
- Finish merging initial SDT (Statically Defined Traces) support, see
cset comments for details about how it all works (Masami Hiramatsu)
- Support attaching eBPF programs to tracepoints (Wang Nan)
- Add demangling of symbols in programs written in the Rust language
(David Tolnay)
- Add support for tracepoints in the python binding, including an
example, that sets up and parses sched:sched_switch events,
tools/perf/python/tracepoint.py (Jiri Olsa)
- Introduce --stdio-color to set up the color output mode selection
in 'annotate' and 'report', allowing emit color escape sequences
when redirecting the output of these tools (Arnaldo Carvalho de
Melo)
- Add 'callindent' option to 'perf script -F', to indent the Intel PT
call stack, making this output more ftrace-like (Adrian Hunter,
Andi Kleen)
- Allow dumping the object files generated by llvm when processing
eBPF scriptlet events (Wang Nan)
- Add stackcollapse.py script to help generating flame graphs (Paolo
Bonzini)
- Add --ldlat option to 'perf mem' to specify load latency for loads
event (e.g. cpu/mem-loads/ ) (Jiri Olsa)
- Tooling support for Intel TopDown counters, recently added to the
kernel (Andi Kleen)"

HYPERVISOR_vcpu_op() passes Linux's idea of vCPU id as a parameter
while Xen's idea is expected. In some cases these ideas diverge so we
need to do remapping.
Convert all callers of HYPERVISOR_vcpu_op() to use xen_vcpu_nr().
Leave xen_fill_possible_map() and xen_filter_cpu_maps() intact as
they're only being called by PV guests before perpu areas are
initialized. While the issue could be solved by switching to
early_percpu for xen_vcpu_id I think it's not worth it: PV guests will
probably never get to the point where their idea of vCPU id diverges
from Xen's.

It may happen that Xen's and Linux's ideas of vCPU id diverge. In
particular, when we crash on a secondary vCPU we may want to do kdump
and unlike plain kexec where we do migrate_to_reboot_cpu() we try
booting on the vCPU which crashed. This doesn't work very well for
PVHVM guests as we have a number of hypercalls where we pass vCPU id
as a parameter. These hypercalls either fail or do something
unexpected.
To solve the issue introduce percpu xen_vcpu_id mapping. ARM and PV
guests get direct mapping for now. Boot CPU for PVHVM guest gets its
id from CPUID. With secondary CPUs it is a bit more
trickier. Currently, we initialize IPI vectors before these CPUs boot
so we can't use CPUID. Use ACPI ids from MADT instead.

Previously the low-level CM call internal to the
_omap4_wait_target_ready/disable calls was responsible for checking for
a valid clkctrl_offs. Now we must also consider the value of the
prcm.omap4.flags because if HWMOD_OMAP4_ZERO_CLKCTRL_OFFSET is set in
the flags then clkctrl_offs of 0 is valid.
Let's add this check into the _omap4_wait_target_ready/disable where we
have access to both the clkctrl_offs and the flags values and simply
return 0 without calling the low level CM call at all, which would have
returned 0 anyway if the clktrl_offs was zero.

HWMOD_OMAP4_ZERO_CLKCTRL_OFFSET to indicate the 0 clkctrl_offs is in
fact valid in this case.

Nearly all modules on OMAP4 and newer platforms have clkctrl offsets
that are non-zero except for the RTC on am335x. Because we rely on a
clkctrl_offset of zero to indicate no clkctrl_offset being present,
lets add a HWMOD_OMAP4_ZERO_CLKCTRL_OFFSET flag to use to indicate
hwmods that have a valid clkctrl_offset of 0.

Add missing sysconfig/sysstatus information
to OMAP3 hwmod. The information has been
checked against OMAP34xx and OMAP36xx TRM.
Without this change DSI block is not reset
during boot, which is required for working
Nokia N950 display.

A handful of fixes before final release:
Marvell Armada:
- One to fix a typo in the devicetree specifying memory ranges for the
crypto engine
- Two to deal with marking PCI and device-memory as strongly ordered to
avoid hardware deadlocks, in particular when enabling above crypto driver.
- Compile fix for PM
Allwinner:
- DT clock fixes to deal with u-boot-enabled framebuffer (simplefb).
- Make R8 (C.H.I.P. SoC) inherit system compatibility from A13 to
make clocks register proper.
Tegra:
- Fix SD card voltage setting on the Tegra3 Beaver dev board
Misc:
- Two maintainers updates for STM32 and STi platforms.
