Merge branch 'akpm' (patches from Andrew)
Merge updates from Andrew Morton:
"Incoming:
- a small number of updates to scripts/, ocfs2 and fs/buffer.c
- most of MM
I still have quite a lot of material (mostly not MM) staged after
linux-next due to -next dependencies. I'll send those across next week
as the preprequisites get merged up"

-* Renesas R-Car Gen2 Clock Pulse Generator (CPG)
-
-The CPG generates core clocks for the R-Car Gen2 SoCs. It includes three PLLs
-and several fixed ratio dividers.
-The CPG also provides a Clock Domain for SoC devices, in combination with the
-CPG Module Stop (MSTP) Clocks.
-
-Required Properties:
-
- - compatible: Must be one of
- - "renesas,r8a7790-cpg-clocks" for the r8a7790 CPG
- - "renesas,r8a7791-cpg-clocks" for the r8a7791 CPG
- - "renesas,r8a7792-cpg-clocks" for the r8a7792 CPG
- - "renesas,r8a7793-cpg-clocks" for the r8a7793 CPG
- - "renesas,r8a7794-cpg-clocks" for the r8a7794 CPG
- and "renesas,rcar-gen2-cpg-clocks" as a fallback.
-
- - reg: Base address and length of the memory resource used by the CPG
-
- - clocks: References to the parent clocks: first to the EXTAL clock, second
- to the USB_EXTAL clock
- - #clock-cells: Must be 1
- - clock-output-names: The names of the clocks. Supported clocks are "main",
- "pll0", "pll1", "pll3", "lb", "qspi", "sdh", "sd0", "sd1", "z", "rcan", and
- "adsp"
- - #power-domain-cells: Must be 0
-
-SoC devices that are part of the CPG/MSTP Clock Domain and can be power-managed
-through an MSTP clock should refer to the CPG device node in their
-"power-domains" property, as documented by the generic PM domain bindings in
-Documentation/devicetree/bindings/power/power_domain.txt.

+===========================
+KASLR for Freescale BookE32
+===========================
+
+The word KASLR stands for Kernel Address Space Layout Randomization.
+
+This document tries to explain the implementation of the KASLR for
+Freescale BookE32. KASLR is a security feature that deters exploit
+attempts relying on knowledge of the location of kernel internals.
+
+Since CONFIG_RELOCATABLE has already supported, what we need to do is
+map or copy kernel to a proper place and relocate. Freescale Book-E
+parts expect lowmem to be mapped by fixed TLB entries(TLB1). The TLB1
+entries are not suitable to map the kernel directly in a randomized
+region, so we chose to copy the kernel to a proper place and restart to
+relocate.
+
+Entropy is derived from the banner and timer base, which will change every
+build and boot. This not so much safe so additionally the bootloader may
+pass entropy via the /chosen/kaslr-seed node in device tree.
+
+We will use the first 512M of the low memory to randomize the kernel
+image. The memory will be split in 64M zones. We will use the lower 8
+bit of the entropy to decide the index of the 64M zone. Then we chose a
+16K aligned offset inside the 64M zone to put the kernel in::
+
+ KERNELBASE
+
+ |--> 64M <--|
+ | |
+ +---------------+ +----------------+---------------+
+ | |....| |kernel| | |
+ +---------------+ +----------------+---------------+
+ | |
+ |-----> offset <-----|
+
+ kernstart_virt_addr
+
+To enable KASLR, set CONFIG_RANDOMIZE_BASE = y. If KASLR is enable and you
+want to disable it at runtime, add "nokaslr" to the kernel cmdline.

+ * At least one Intel Cherry Trail based device which ship with Windows 10
+ * (Lenovo YogaBook YB1-X91L/F tablet), have this weird INT33FE ACPI device
+ * with a CRS table with 2 I2cSerialBusV2 resources, for 2 different chips
+ * attached to various i2c busses:
+ * 1. The Whiskey Cove PMIC, which is also described by the INT34D3 ACPI device
+ * 2. TI BQ27542 Fuel Gauge Controller
+ *
+ * So this driver is a stub / pseudo driver whose only purpose is to
+ * instantiate i2c-client for battery fuel gauge, so that standard i2c driver
+ * for these chip can bind to the it.
