8a4e8f8dfc media: rc: new driver for early iMon device
These devices were supported by the lirc_imon.c driver which was removed
from staging in commit f41003a23a02 ("[media] staging: lirc_imon: port
remaining usb ids to imon and remove").

2d17269151 clk: davinci: New driver for davinci PLL clocks
This adds a new driver for mach-davinci PLL clocks. This is porting the
code from arch/arm/mach-davinci/clock.c to the common clock framework.
Additionally, it adds device tree support for these clocks.

The ifeq ($(CONFIG_COMMON_CLK), y) in the Makefile is needed to prevent
compile errors until the clock code in arch/arm/mach-davinci is removed.

Note: although there are similar clocks for TI Keystone we are not able
to share the code for a few reasons. The keystone clocks are device tree
only and use legacy one-node-per-clock bindings. Also the register
layouts are a bit different, which would add even more if/else mess
to the keystone clocks. And the keystone PLL driver doesn't support
setting clock rates.

1f57bc12d8 fw_cfg: add a public uapi header
Create a common header file for well-known values and structures to be
shared by the Linux kernel with qemu or other projects.

It is based from qemu/docs/specs/fw_cfg.txt which references
qemu/include/hw/nvram/fw_cfg_keys.h "for the most up-to-date and
authoritative list" & vmcoreinfo.txt. Those files don't have an
explicit license, but qemu/hw/nvram/fw_cfg.c is BSD-license, so
Michael S. Tsirkin suggested to use the same license.

The patch intentionally left out DMA & vmcoreinfo structures &
defines, which are added in the commits making usage of it.

Pull percpu fixes from Tejun Heo:
 "Late percpu pull request for v4.16-rc6.

   - percpu allocator pool replenishing no longer triggers OOM or
     warning messages.

     Also, the alloc interface now understands __GFP_NORETRY and
     __GFP_NOWARN. This is to allow avoiding OOMs from userland
     triggered actions like bpf map creation.

     Also added cond_resched() in alloc loop.

   - perpcu allocation now can be interrupted by kill sigs to avoid
     deadlocking OOM killer.

   - Added Dennis Zhou as a co-maintainer.

     He has rewritten the area map allocator, understands most of the
     code base and has been responsive for all bug reports"

* 'for-4.16-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu:
  percpu_ref: Update doc to dissuade users from depending on internal RCU grace periods
  mm: Allow to kill tasks doing pcpu_alloc() and waiting for pcpu_balance_workfn()

c690eddc2f CRIS: Drop support for the CRIS port
The port was added back in 2000 so it's no longer even a good source
of inspiration for newer ports (if it ever was)

The last SoC (ARTPEC-3) with a CRIS main CPU was launched in 2008.

Coupled with time and working developer board hardware being
in low supply, it's time to drop the port from Linux.

So long and thanks for all the fish!

bb9d812643 arch: remove tile port
The Tile architecture port was added by Chris Metcalf in 2010, and
maintained until early 2018 when he orphaned it due to his departure
from Mellanox, and nobody else stepped up to maintain it. The product
line is still around in the form of the BlueField SoC, but no longer
uses the Tile architecture.

There are also still products for sale with Tile-GX SoCs, notably the
Mikrotik CCR router family. The products all use old (linux-3.3) kernels
with lots of patches and won't be upgraded by their manufacturers. There
have been efforts to port both OpenWRT and Debian to these, but both
projects have stalled and are very unlikely to be continued in the future.

Given that we are reasonably sure that nobody is still using the port
with an upstream kernel any more, it seems better to remove it now while
the port is in a good shape than to let it bitrot for a few years first.

4ba66a9760 arch: remove blackfin port
The Analog Devices Blackfin port was added in 2007 and was rather
active for a while, but all work on it has come to a standstill
over time, as Analog have changed their product line-up.

Aaron Wu confirmed that the architecture port is no longer relevant,
and multiple people suggested removing blackfin independently because
of some of its oddities like a non-working SMP port, and the amount of
duplication between the chip variants, which cause extra work when
doing cross-architecture changes.

b8c9c8f019 arch: remove score port
The Sunplus S+core architecture was added in 2009 by Chen Liqin,
who has been co-maintaining it with Lennox Wu <lennox.wu@gmail.com>
since then, but after they both left the company, nobody else has shown
any interest in the port and it has seen almost no activity other than
tree-wide changes.

The gcc port was removed a few years ago due to the inactivity.

While the sunplus website still advertises products with unspecified
RISC cores that might be S+core based, it's very clear that the Linux
port is completely abandoned at this point.

This removes all files related to the architecture.

553b085c20 arch: remove m32r port
The Mitsubishi/Renesas m32r architecture has been around for many years,
but the Linux port has been obsolete for a very long time as well, with
the last significant updates done for linux-2.6.14.

While some m32r microcontrollers are still being marketed by Renesas,
those are apparently no longer possible to support, mainly due to the
lack of an external memory interface.

Hirokazu Takata was the maintainer until the architecture got marked
Orphaned in 2014.

The Fujitsu FRV kernel port has been around for a long time, but has not
seen regular updates in several years and instead was marked 'Orphaned'
in 2016 by long-time maintainer David Howells.

The SoC product line apparently is apparently still around in the form
of the Socionext Milbeaut image processor, but this one no longer uses
the FRV CPU cores.

This removes all FRV specific files from the kernel.

f46f11dc1e ARM SCMI support for v4.17
ARM System Control and Management Interface(SCMI)[1] is more flexible and
 easily extensible than any of the existing interfaces.
 
 Few existing as well as future ARM platforms provide micro-controllers
 to abstract various power and other system management tasks which have
 similar interfaces, both in terms of the functions that are provided by
 them, and in terms of how requests are communicated to them.
 
 There are quite a few protocols like ARM SCPI, TI SCI, QCOM RPM, Nvidia Tegra
 BPMP, and so on already. This specification is to standardize and avoid any
 further fragmentation in the design of such interface by various vendors.
 
 The current SCMI driver implementation is very basic and initial support.
 It lacks support for notifications, asynchronous/delayed response, perf/power
 statistics region and sensor register region.
 
 Mailbox is the only form of transport supported currently in the driver.
 SCMI supports interrupt based mailbox communication, where, on completion
 of the processing of a message, the caller receives an interrupt as well as
 polling for completion.
 
 SCMI is designed to minimize the dependency on the mailbox/transport
 hardware. So in terms of SCMI, each channel in the mailbox includes
 memory area, doorbell and completion interrupt.
 
 However the doorbell and completion interrupt is highly mailbox dependent
 which was bit of controversial as part of SCMI/mailbox discussions.
 
 Arnd and me discussed about the few aspects of SCMI and the mailbox framework:
 
 1. Use of mailbox framework for doorbell type mailbox controller:
    - Such hardware may not require any data to be sent to signal the remote
      about the presence of a message. The channel will have in-built
      information on how to trigger the signal to the remote.
      There are few mailbox controller drivers which are purely doorbell based.
      e.g.QCOM IPC, STM, Tegra, ACPI PCC,..etc
 
 2. Supporting other mailbox controller:
    - SCMI just needs a mechanism to signal the remote firmware. Such
      controller may need fixed message to be sent to trigger a doorbell.
      In such case we may need to get that data from DT and pass the same
      to the controller. It's not covered in the current DT binding, but
      can be extended as optional property in future.
 
      However handling notifications may be interesting on such mailbox, but
      again there is no way to interpret what the data field(remote message)
      means, it could be a bit mask or a number or don't-care.
 
 Arnd mentioned that he doesn't like the way the mailbox binding deals
 with doorbell-type hardware, but we do have quite a few precedent drivers
 already and changing the binding to add a data field would not make it any
 better, but could cause other problems. So he is happy with the status quo
 of SCMI implementation.
