Christoffer Dall (KVM-ARM maintainer) says:
"There are a few changes in this pull request touching things
outside KVM, but they should all carry the necessary acks and it
made the merge process much easier to do it this way."
though actually the irqchip maintainers' acks didn't make it into the
patches. Marc Zyngier, who is both irqchip and KVM-ARM maintainer,
later acked at http://mid.gmane.org/573351D1.4060303@arm.com ('more

git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull ARC updates from Vineet Gupta:
"We have a relatively big changeset for ARC for 4.7.
The highlight is support for EZChip (now Mellanox) NPS-400 network
processor, a 400-Gb throughput C-programmable packet processor based
on ARC700 cores from Synopsys. See
http://www.mellanox.com/related-docs/prod_npu/PB_NPS-400.pdf
Also present are irqchip and clocksource drivers for NPS as agreed
with respective maintainers to go via ARC tree due to an soc header
dependency. I have the needed ACKs from Jason, Marc, Daniel. You
might run into a trivial merge conflict in drivers/irqchip/*
This EZChip platform support required some deep changes in ARC
architecture code and also opportunity to cleanup past sins (legacy
irq domains, missing irq domain lookup, hard coded timer irqs...)
Summary:
- Support for EZChip (now Mellanox) NPS-400 Network processor based
on ARC700
- NPS interrupt controller and clocksource drivers
- ARC timers probed off DT
- ARC iqrchips switching to linear domain (upgrade from legacy
domains)"

git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security subsystem updates from James Morris:
"Highlights:
- A new LSM, "LoadPin", from Kees Cook is added, which allows forcing
of modules and firmware to be loaded from a specific device (this
is from ChromeOS, where the device as a whole is verified
cryptographically via dm-verity).
This is disabled by default but can be configured to be enabled by
default (don't do this if you don't know what you're doing).
- Keys: allow authentication data to be stored in an asymmetric key.
Lots of general fixes and updates.
- SELinux: add restrictions for loading of kernel modules via
finit_module(). Distinguish non-init user namespace capability
checks. Apply execstack check on thread stacks"

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt:
"This includes two new updates for the ftrace infrastructure.
- With the changing of the code for filtering events by pid, from a
list of pids to a bitmask, we can now easily implement following
forks. With a new tracing option "event-fork" which, when set,
will have tasks with pids in set_event_pid, when they fork, to have
their child pids added to set_event_pid and the child will be
traced as well.
Note, if "event-fork" is set and a task with its pid in
set_event_pid exits, its pid will be removed from set_event_pid
- The addition of Tom Zanussi's hist triggers. This includes a very
thorough documentatino on how to use the hist triggers with events.
This introduces a quick and easy way to get histogram data from
events and their fields.
Some other cleanups and updates were added as well. Like Masami
Hiramatsu added test cases for the event trigger and hist triggers.
Also I added a speed up of filtering by using a temp buffer when
filters are set"

"Driver updates for ARM SoCs, these contain various things that touch

For the most part, this is now related to power management

Pull ARM 64-bit DT updates from Arnd Bergmann:
"We continue ramping up platform support for 64-bit ARM machines, with
111 individual non-merge changesets touching 21 platforms.
The LG1312 platform is completely new and is the first ARM platform by
LG that we support in the mainline kernel. Two other SoCs got added
that are updated versions of existing SoC families, so the port mainly
consists of new dts files:
- The Hisilicon Hip06/D03 is the latest server platform from
Huawei/Hisilicon, and follows the Hip05/D02 platform.
- Rockchip RK3399 follows the 32-bit RK3288 that is popular in
low-end Chromebooks and the 64-bit RK3368 that is mainly found in
chinese Android TV boxes.
The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620) gets a
long-awaited overhaul with a lot of devices enabled in the DT, so it
should be much more usable with a mainline kernel now. See also
https://plus.google.com/111524780435806926688/posts/PeGb2VsNhJd
A lot of work went into enabling new device drivers on existing
machines, but we also have a couple of new commercially available
machines:
- Google Pixel C laptop based on Tegra210
- Hardkernel Odroid C2 Based on Amlogic Meson GXBB (S905)
- Geekbuying GeekBox based on Rockchip RK3368
And finally, a couple of reference or development platforms that are
not end-user platforms but are used for trying out the respective SoC
platforms:
- Amlogic Meson GXBB P200 and P201 development systems
- NXP Layerscape 1043A QDS development board
- Hisilicon Hip06 D03 server board, as mentioned above
- LG1312 Reference Design

The three platforms that are added with the "soc" branch are here as
well, and we add some related machine files:
- For Aspeed AST2400/AST2500, we get the evaluation platform and the
Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC

Pull ARM SoC platform updates from Arnd Bergmann:
"We get support for three new 32-bit SoC platforms this time.
The amount of changes in arch/arm for any of them is miniscule, as all
the interesting code is in device driver subsystems (irqchip, clk,
pinctrl, ...) these days. I'm listing them here, as the addition of
the Kconfig statement is the main relevant milestone for a new
platform. In each case, some drivers are are shared with existing
platforms, while other drivers are added for v4.7 as well, or come in
a later release.
- The Aspeed platform is probably the most interesting one, this is
what most whitebox servers use as their baseboard management
controller. We get support for the very common ast2400 and ast2500
SoCs. The OpenBMC project focuses on this chip, and the LWN
article about their ELC 2016 presentation at
https://lwn.net/Articles/683320/
triggered the submission, but the code comes from IBM's OpenPOWER
team rather than the team at Facebook. There are still a lot more
drivers that need to get added over time, and I hope both teams can
work together on that.
- OXNAS is an old platform for Network Attached Storage devices from
Oxford Semiconductor. There are models with ARM10 (!) and
ARM11MPCore cores, but for now, we only support the original ARM9
based versions. The product lineup was subsequently part of PLX,
Avago and now the new Broadcom Ltd.
https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas
has some more information.
- V2M-MPS2 is a prototyping platform from ARM for their Cortex-M
cores and is related to the existing Realview / Versatile Express
lineup, but without MMU.
We now support various NOMMU platforms, so adding a new one is
fairly straightforward.
http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/
has detailed information about the platform.
Other noteworthy updates:
- Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain
Lemieux are now maintaining the platform.
This is an older ARM9 based platform from NXP (not Freescale), but
it remains in use in embedded markets.
- Kevin Hilman is now co-maintaining the Amlogic Meson platform for
both 32-bit and 64-bit ARM, and started contributing some patches.
- As is often the case, work on the OMAP platforms makes up the bulk
of the actual SoC code changes in arch/arm, but there isn't a lot
of that either"

My laptop that uses the intel 7680 iwlwifi module would no longer
connects to the network. It would fail with a "Microcode SW error
detected." and spew out register state over and over again without ever
connecting to the network.
The cause is mis-merge in commit 909b27f70643, where David seems to have
lost some of the changes to iwl_mvm_set_tx_cmd() from commit
5c08b0f5026f ("iwlwifi: mvm: don't override the rate with the AMSDU
len").
The reason seems to be a conflict with commit d8fe484470dd ("iwlwifi:
mvm: add support for new TX CMD API"), which touched a line adjacent to
the changes in 909b27f70643.
David missed the fact that "info->driver_data[0]" had become
"skb_info->driver_data[0]". Then he removed the skb_info because it was
unused.
This just re-updates iwl_mvm_set_tx_cmd() with the lost two lines.

xfs: concurrent readdir hangs on data buffer locks
Revert "btrfs: switch to ->iterate_shared()"
|
|
There's a three-process deadlock involving shared/exclusive barriers
and inverted lock orders in the directory readdir implementation.
It's a pre-existing problem with lock ordering, exposed by the
VFS parallelisation code.
process 1 process 2 process 3
--------- --------- ---------
readdir
iolock(shared)
get_leaf_dents
iterate entries
ilock(shared)
map, lock and read buffer
iunlock(shared)
process entries in buffer
.....
readdir
iolock(shared)
get_leaf_dents
iterate entries
ilock(shared)
map, lock buffer
<blocks>
finish ->iterate_shared
file_accessed()
->update_time
start transaction
ilock(excl)
<blocks>
.....
finishes processing buffer
get next buffer
ilock(shared)
<blocks>
And that's the deadlock.
Fix this by dropping the current buffer lock in process 1 before
trying to map the next buffer. This means we keep the lock order of
ilock -> buffer lock intact and hence will allow process 3 to make
progress and drop it's ilock(shared) once it is done.

MSR 0x2f8 accessed the 124th Variable Range MTRR ever since MTRR support
was introduced by 9ba075a664df ("KVM: MTRR support").
0x2f8 became harmful when 910a6aae4e2e ("KVM: MTRR: exactly define the
size of variable MTRRs") shrinked the array of VR MTRRs from 256 to 8,
which made access to index 124 out of bounds. The surrounding code only
WARNs in this situation, thus the guest gained a limited read/write
access to struct kvm_arch_vcpu.
0x2f8 is not a valid VR MTRR MSR, because KVM has/advertises only 16 VR
MTRR MSRs, 0x200-0x20f. Every VR MTRR is set up using two MSRs, 0x2f8
was treated as a PHYSBASE and 0x2f9 would be its PHYSMASK, but 0x2f9 was
not implemented in KVM, therefore 0x2f8 could never do anything useful
and getting rid of it is safe.
This fixes CVE-2016-3713.

Neither APICv nor AVIC actually need the first argument of
hwapic_isr_update, but the vCPU makes more sense than passing the
pointer to the whole virtual machine! In fact in the APICv case it's
just happening that the vCPU is used implicitly, through the loaded VMCS.
The second argument instead is named differently, make it consistent.

* Do not intercept CR8 since this should be handled by AVIC HW.
* Also, we don't need to sync cr8/V_TPR and APIC backing page.

This patch introduces a new mechanism to inject interrupt using AVIC.
Since VINTR is not supported when enable AVIC, we need to inject
interrupt via APIC backing page instead.
This patch also adds support for AVIC doorbell, which is used by
KVM to signal a running vcpu to check IRR for injected interrupts.

This patch introduces AVIC-related data structure, and AVIC
initialization code.
There are three main data structures for AVIC:
* Virtual APIC (vAPIC) backing page (per-VCPU)
* Physical APIC ID table (per-VM)
* Logical APIC ID table (per-VM)
Currently, AVIC is disabled by default. Users can manually
enable AVIC via kernel boot option kvm-amd.avic=1 or during
kvm-amd module loading with parameter avic=1.

commit 3491caf2755e ("KVM: halt_polling: provide a way to qualify
wakeups during poll") added more aggressive shrinking of the
polling interval if the wakeup did not match some criteria. This
still allows to keep polling enabled if the polling time was
smaller that the current max poll time (block_ns <= vcpu->halt_poll_ns).
Performance measurement shows that even more aggressive shrinking
(shrink polling on any invalid wakeup) reduces absolute and relative
(to the workload) CPU usage even further.

The most recent release of AXS103 [v1.1] is proven to work
at 100 MHz in dual-core mode so this change uses mentioned feature.
For that we:
* Update axc003_idu.dtsi with mention of really-used CPU clock freq
* Remove clock override in AXS platform code for dual-core HW
Note we're still leaving a hack for clock "downgrade" on early boot
for quad-core hardware.
Also note this change will break functionality of AXS103 v1.0 hardware.
That means all users of AXS103 __must__ upgrade their boards with the
most recent firmware.
