When using a virtual SCSI disk in a VMWare VM if blkdev_issue_zeroout is used
data can be improperly zeroed out using the mptfusion driver. This patch
disables write_same for this driver and the vmware subsystem_vendor which
ensures that manual zeroing out is used instead.

In cases where board has below memory DT node
memory{
device_type = "memory";
reg = <0x80000000 0x80000000>;
};
Check on the memory range in fdt.c will always fail because it is
comparing MAX_PHYS_ADDR with base + size, in fact it should compare
it with base + size - 1.
This issue was originally noticed on Qualcomm IFC6410 board.
Without this patch kernel shows up noticed unnecessary warnings
[ 0.000000] Machine model: Qualcomm APQ8064/IFC6410
[ 0.000000] Ignoring memory range 0xffffffff - 0x100000000

This patch fixes the check involved in generating this warning and
as a result it also fixes the wrong size calculation.

With the introduction of DT based idle states, CPUidle drivers for ARM
can now initialize idle states data through properties in the device tree.
This patch adds code to the big.LITTLE CPUidle driver to dynamically
initialize idle states data through the updated device tree source file.

This patch implements a generic CPU idle driver for ARM64 machines.
It relies on the DT idle states infrastructure to initialize idle
states count and respective parameters. Current code assumes the driver
is managing idle states on all possible CPUs but can be easily
generalized to support heterogenous systems and build cpumasks at
runtime using MIDRs or DT cpu nodes compatible properties.
The driver relies on the arm64 CPU operations to call the idle
initialization hook used to parse and save suspend back-end specific
idle states information upon probing.
Idle state index 0 is always initialized as a simple wfi state, ie always
considered present and functional on all ARM64 platforms.
Idle state indices higher than 0 trigger idle state entry by calling
the cpu_suspend function, that triggers the suspend operation through
the CPU operations suspend back-end hook. cpu_suspend passes the idle
state index as a parameter so that the CPU operations suspend back-end
can retrieve the required idle state data by using the idle state
index to execute a look-up on its internal data structures.

On most common ARM systems, the low-power states a CPU can be put into are
not discoverable in HW and require device tree bindings to describe
power down suspend operations and idle states parameters.
In order to enable DT based idle states and configure idle drivers, this
patch implements the bulk infrastructure required to parse the device tree
idle states bindings and initialize the corresponding CPUidle driver states
data.
The parsing API accepts a start index that defines the first idle state
that should be initialized by the parsing code in order to give new and
legacy driver flexibility over which states should be parsed using the
new DT mechanism.
The idle states node(s) is obtained from the phandle list of the first cpu
in the driver cpumask; the kernel checks that the idle state node phandle
is the same for all CPUs in the driver cpumask before declaring the idle state
as valid and start parsing its content.
The idle state enter function pointer is initialized through DT match
structures passed in by the CPUidle driver, so that ARM legacy code can
cope with platform specific idle entry method based on compatible
string matching and the code used to initialize the enter function pointer
can be moved to the DT generic layer.

The event type masks can change asynchronously. These changes are reported
by SCLP to the OS by state-change events which are retrieved with the read
event data command. The SCLP driver has a request queue, there is a window
where the read event data request has not completed yet but the SCLP console
drivers are trying to queue output requests. As the masks are not updated
yet the requests are discarded.
The simplest fix is to queue the console requests independent of the
event type masks and rely on SCLP to return with an error code if a
specific event type is not available.

ACPI device enumeration mechanism changed a lot since 3.16-rc1.
ACPI device objects with _HID will be enumerated to platform bus by default.
For the existing PNP drivers that probe the PNPACPI devices, the device ids
are listed explicitly in drivers/acpi/acpi_pnp.c.
But ACPI folks will continue their effort on shrinking this id list by
converting the PNP drivers to platform drivers, for the devices that don't
belong to PNP bus in nature.

The kernel used to contain two functions for length-delimited,
case-insensitive string comparison, strnicmp with correct semantics
and a slightly buggy strncasecmp. The latter is the POSIX name, so
strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper
for the new strncasecmp to avoid breaking existing users.
To allow the compat wrapper strnicmp to be removed at some point in
the future, and to avoid the extra indirection cost, do
s/strnicmp/strncasecmp/g.
