powerpc updates for 4.18 

Notable changes:
 
  - Support for split PMD page table lock on 64-bit Book3S (Power8/9).
 
  - Add support for HAVE_RELIABLE_STACKTRACE, so we properly support live
    patching again.
 
  - Add support for patching barrier_nospec in copy_from_user() and syscall entry.
 
  - A couple of fixes for our data breakpoints on Book3S.
 
  - A series from Nick optimising TLB/mm handling with the Radix MMU.
 
  - Numerous small cleanups to squash sparse/gcc warnings from Mathieu Malaterre.
 
  - Several series optimising various parts of the 32-bit code from Christophe Leroy.
 
  - Removal of support for two old machines, "SBC834xE" and "C2K" ("GEFanuc,C2K"),
    which is why the diffstat has so many deletions.
 
 And many other small improvements & fixes.
 
 There's a few out-of-area changes. Some minor ftrace changes OK'ed by Steve, and
 a fix to our powernv cpuidle driver. Then there's a series touching mm, x86 and
 fs/proc/task_mmu.c, which cleans up some details around pkey support. It was
 ack'ed/reviewed by Ingo & Dave and has been in next for several weeks.

Marvell Discovery mv64[345]6x System Controller chips
===========================================================
The Marvell mv64[345]60 series of system controller chips contain
many of the peripherals needed to implement a complete computer
system. In this section, we define device tree nodes to describe
the system controller chip itself and each of the peripherals
which it contains. Compatible string values for each node are
prefixed with the string "marvell,", for Marvell Technology Group Ltd.
1) The /system-controller node
This node is used to represent the system-controller and must be
present when the system uses a system controller chip. The top-level
system-controller node contains information that is global to all
devices within the system controller chip. The node name begins
with "system-controller" followed by the unit address, which is
the base address of the memory-mapped register set for the system
controller chip.
Required properties:
- ranges : Describes the translation of system controller addresses
for memory mapped registers.
- clock-frequency: Contains the main clock frequency for the system
controller chip.
- reg : This property defines the address and size of the
memory-mapped registers contained within the system controller
chip. The address specified in the "reg" property should match
the unit address of the system-controller node.
- #address-cells : Address representation for system controller
devices. This field represents the number of cells needed to
represent the address of the memory-mapped registers of devices
within the system controller chip.
- #size-cells : Size representation for the memory-mapped
registers within the system controller chip.
- #interrupt-cells : Defines the width of cells used to represent
interrupts.
Optional properties:
- model : The specific model of the system controller chip. Such
as, "mv64360", "mv64460", or "mv64560".
- compatible : A string identifying the compatibility identifiers
of the system controller chip.
The system-controller node contains child nodes for each system
controller device that the platform uses. Nodes should not be created
for devices which exist on the system controller chip but are not used
Example Marvell Discovery mv64360 system-controller node:
system-controller@f1000000 { /* Marvell Discovery mv64360 */
#address-cells = <1>;
#size-cells = <1>;
model = "mv64360"; /* Default */
compatible = "marvell,mv64360";
clock-frequency = <133333333>;
reg = <0xf1000000 0x10000>;
virtual-reg = <0xf1000000>;
ranges = <0x88000000 0x88000000 0x1000000 /* PCI 0 I/O Space */
0x80000000 0x80000000 0x8000000 /* PCI 0 MEM Space */
0xa0000000 0xa0000000 0x4000000 /* User FLASH */
0x00000000 0xf1000000 0x0010000 /* Bridge's regs */
0xf2000000 0xf2000000 0x0040000>;/* Integrated SRAM */
[ child node definitions... ]
}
2) Child nodes of /system-controller
a) Marvell Discovery MDIO bus
The MDIO is a bus to which the PHY devices are connected. For each
device that exists on this bus, a child node should be created. See
the definition of the PHY node below for an example of how to define
a PHY.
Required properties:
- #address-cells : Should be <1>
- #size-cells : Should be <0>
- compatible : Should be "marvell,mv64360-mdio"
Example:
mdio {
#address-cells = <1>;
#size-cells = <0>;
compatible = "marvell,mv64360-mdio";
ethernet-phy@0 {
......
};
};
b) Marvell Discovery ethernet controller
The Discover ethernet controller is described with two levels
of nodes. The first level describes an ethernet silicon block
and the second level describes up to 3 ethernet nodes within
that block. The reason for the multiple levels is that the
registers for the node are interleaved within a single set
of registers. The "ethernet-block" level describes the
shared register set, and the "ethernet" nodes describe ethernet
port-specific properties.
Ethernet block node

.......
};
};
