Instead of hacking the configuration of the FPI bus into the arch code
add an own bus driver for this internal bus. The FPI bus is the main
bus of the SoC. This bus driver makes sure the bus is configured
correctly before the child drivers are getting initialized. This driver
will probably also be used on different SoCs later.

Pull x86 asm updates from Ingo Molnar:
- Introduce the ORC unwinder, which can be enabled via
CONFIG_ORC_UNWINDER=y.
The ORC unwinder is a lightweight, Linux kernel specific debuginfo
implementation, which aims to be DWARF done right for unwinding.
Objtool is used to generate the ORC unwinder tables during build, so
the data format is flexible and kernel internal: there's no
dependency on debuginfo created by an external toolchain.
The ORC unwinder is almost two orders of magnitude faster than the
(out of tree) DWARF unwinder - which is important for perf call graph
profiling. It is also significantly simpler and is coded defensively:
there has not been a single ORC related kernel crash so far, even
with early versions. (knock on wood!)
But the main advantage is that enabling the ORC unwinder allows
CONFIG_FRAME_POINTERS to be turned off - which speeds up the kernel
measurably:
With frame pointers disabled, GCC does not have to add frame pointer
instrumentation code to every function in the kernel. The kernel's
.text size decreases by about 3.2%, resulting in better cache
utilization and fewer instructions executed, resulting in a broad
kernel-wide speedup. Average speedup of system calls should be
roughly in the 1-3% range - measurements by Mel Gorman [1] have shown
a speedup of 5-10% for some function execution intense workloads.
The main cost of the unwinder is that the unwinder data has to be
stored in RAM: the memory cost is 2-4MB of RAM, depending on kernel
config - which is a modest cost on modern x86 systems.
Given how young the ORC unwinder code is it's not enabled by default
- but given the performance advantages the plan is to eventually make
it the default unwinder on x86.
See Documentation/x86/orc-unwinder.txt for more details.
- Remove lguest support: its intended role was that of a temporary
proof of concept for virtualization, plus its removal will enable the
reduction (removal) of the paravirt API as well, so Rusty agreed to
its removal. (Juergen Gross)

Maintaining a subsystem with linux-kernel as the main list is painful
as it has way to much traffic. On the other hand the dma-mapping
subsystem is small enough that a list on its own would be silly.

HSDK board manages its clocks using various PLLs. These PLL have same
dividers and corresponding control registers mapped to different addresses.
So we add one common driver for such PLLs.
Each PLL on HSDK board consists of three dividers: IDIV, FBDIV and
ODIV. Output clock value is managed using these dividers.
We add pre-defined tables with supported rate values and appropriate
configurations of IDIV, FBDIV and ODIV for each value.
As of today we add support for PLLs that generate clock for the
HSDK arc cpus, system, ddr, AXI tunnel and hdmi.
By this patch we add support for several plls (arc cpus pll and others),
so we had to use two different init types: CLK_OF_DECLARE for arc cpus pll
and regular probing for others plls.

Up until now when configuring a generic kernel all board config
fragments have been merged by default unless boards are explicitly
selected by the user specifying BOARDS=.
In many cases this is sub-optimal, since some boards don't make sense to
include in some kernels. For example the MIPS SEAD-3 development board
has only ever been used with 32 bit CPUs, so including support for the
SEAD-3 in a 64 bit kernel is wasteful.
This patch introduces support for specifying requirements in board
config fragments, using comments formatted like so:
# require CONFIG_BLA=y
For example the SEAD-3 board could specify that it should only be merged
for 32 bit kernels using a requirement line like the following:
# require CONFIG_32BIT=y
A new generic-board-config.sh script is introduced to handle selecting
the board config fragments to merge & calling merge_config.sh to merge
them. In order to allow requirements to check Kconfig symbols that are
implicitly selected, rather than explicitly specified by
generic_defconfig or one of the ISA config fragments, an intermediate
.config file is saved & used as a reference when checking requirements.

Reimplement RINT.<D|S> kernel emulation so that all RINT.<D|S>
specifications are met.
For the sake of simplicity, let's analyze RINT.S only. Prior to
this patch, RINT.S emulation was essentially implemented as (in
pseudocode) <output> = ieee754sp_flong(ieee754sp_tlong(<input>)),
where ieee754sp_tlong() and ieee754sp_flong() are functions
providing conversion from double to integer, and from integer
to double, respectively. On surface, this implementation looks
correct, but actually fails in many cases. Following problems
were detected:
1. NaN and infinity cases will not be handled properly. The
function ieee754sp_flong() never returns NaN nor infinity.
2. For RINT.S, for all inputs larger than LONG_MAX, and smaller
than FLT_MAX, the result will be wrong, and the overflow
exception will be erroneously set. A similar problem for
negative inputs exists as well.
3. For some rounding modes, for some negative inputs close to zero,
the return value will be zero, and should be -zero. This is
because ieee754sp_flong() never returns -zero.
This patch removes the problems above by implementing dedicated
functions for RINT.<D|S> emulation.
The core of the new function functionality is adapted version of
the core of the function ieee754sp_tlong(). However, there are many
details that are implemented to match RINT.<D|S> specification. It
should be said that the functionality of ieee754sp_tlong() actually
closely corresponds to CVT.L.S instruction, and it is used while
emulating CVT.L.S. However, RINT.S and CVT.L.S instructions differ
in many aspects. This patch fulfills missing support for RINT.<D|S>.

Hyper-V Sockets (hv_sock) supplies a byte-stream based communication
mechanism between the host and the guest. It uses VMBus ringbuffer as the
transportation layer.
With hv_sock, applications between the host (Windows 10, Windows Server
2016 or newer) and the guest can talk with each other using the traditional
socket APIs.
More info about Hyper-V Sockets is available here:

UniPhier SoCs contain AIDET (ARM Interrupt Detector). This is intended
to provide additional features that are not covered by GIC. The main
purpose is to provide logic inverter to support low level and falling
edge trigger types for interrupt lines from on-board devices.

git://anongit.freedesktop.org/git/drm-intel into drm-next
Final pile of features for 4.14
- New ioctl to change NOA configurations, plus prep (Lionel)
- CCS (color compression) scanout support, based on the fancy new
modifier additions (Ville&Ben)
- Document i915 register macro style (Jani)
- Many more gen10/cnl patches (Rodrigo, Pualo, ...)
- More gpu reset vs. modeset duct-tape to restore the old way.
- prep work for cnl: hpd_pin reorg (Rodrigo), support for more power
wells (Imre), i2c pin reorg (Anusha)
- drm_syncobj support (Jason Ekstrand)
- forcewake vs gpu reset fix (Chris)
- execbuf speedup for the no-relocs fastpath, anv/vk low-overhead ftw (Chris)
- switch to idr/radixtree instead of the resizing ht for execbuf id->vma
lookups (Chris)
gvt:
- MMIO save/restore optimization (Changbin)
- Split workload scan vs. dispatch for more parallel exec (Ping)
- vGPU full 48bit ppgtt support (Joonas, Tina)
- vGPU hw id expose for perf (Zhenyu)
Bunch of work all over to make the igt CI runs more complete/stable.
Watch https://intel-gfx-ci.01.org/tree/drm-tip/shards-all.html for
progress in getting this ready. Next week we're going into production
mode (i.e. will send results to intel-gfx) on hsw, more platforms to
come.
Also, a new maintainer tram, I'm stepping out. Huge thanks to Jani for
being an awesome co-maintainer the past few years, and all the best
for Jani, Joonas&Rodrigo as the new maintainers!

Pull irq fixes from Thomas Gleixner:
"A pile of smallish changes all over the place:
- Add a missing ISB in the GIC V1 driver
- Remove an ACPI version check in the GIC V3 ITS driver
- Add the missing irq_pm_shutdown function for BRCMSTB-L2 to avoid
spurious wakeups
- Remove the artifical limitation of ITS instances to the number of
NUMA nodes which prevents utilizing the ITS hardware correctly
- Prevent a infinite parsing loop in the GIC-V3 ITS/MSI code
- Honour the force affinity argument in the GIC-V3 driver which is
required to make perf work correctly
- Correctly report allocation failures in GIC-V2/V3 to avoid using
half allocated and initialized interrupts.
- Fixup checks against nr_cpu_ids in the generic IPI code"

The driver is actually for T-PHY which supports USB3.0, PCIe and SATA,
and supports more SoCs now, but not just only for series of mt65xx SoCs,
so the name of file, data struct, functions etc with 'mt65xx' may cause
misunderstanding when new SoCs are supported. Here rename them to reflect
the real functions and also enhance readability.
And also update MAINTAINERS file to reflect the correct driver
