not hurt to drop "PH1_" because "UNIPHIER_" already well specifies
the SoC family. Also, rename files for consistency.
...meaning that it is currently not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular

We also delete the MODULE_LICENSE tag etc. since all that information

Add support for setting up GPIO pin interrupts in the lpc18xx pinctrl

routing to the GPIO pin interrupt (PINT) block. The routing uses the
GPIO namespace and not the pin namespace so a lookup is preformed on
the pin.
Routing configuration is done in the device tree by using the new
nxp,gpio-pin-interrupt property. This property takes single parameter

For older SoCs using SH cores and some 32-bit ARM SoCs the PFC
hardware also provides GPIO functionality. On the majority of
32-bit ARM SoCs from Renesas and so far all ARM64 SoCs the GPIO
feature is provided by separate hardware blocks.
So far GPIO support in the PFC driver has been compiled-in for
the majority of the SoCs, but with this patch applied the SoCs
with PFC support may select from one of the following:
- CONFIG_PINCTRL_SH_PFC - Used if PFC lacks GPIO hardware
- CONFIG_PINCTRL_SH_PFC_GPIO - Used if PFC includes GPIO support
This patch results in the following changes:
- The GPIO functionality is only compiled-in on relevant SoCs
- The number of lines of code is reduced
Build tested using the following configurations:
- r8a7795 -> CONFIG_PINCTRL_SH_PFC_GPIO=n -> OK (ARM64)
- r8a7790 -> CONFIG_PINCTRL_SH_PFC_GPIO=n -> OK (ARM)

ideapad-laptop: Add Lenovo Yoga 700 to no_hw_rfkill dmi list
Like the Yoga 900 models the Lenovo Yoga 700 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.
This commit adds the Lenovo Yoga 700 to the no_hw_rfkill dmi list, fixing
the wifi breakage.
If we detect that there is nothing to do just set the flag and do not
check if it was already set before. Races really do not matter. If the
flag is set by any code then the shepherd will start dealing with the
situation and reenable the vmstat workers when necessary again.
Since commit 0eb77e988032 ("vmstat: make vmstat_updater deferrable again
and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
a particular cpu to be handled by vmstat_shepherd. This might trigger a
VM_BUG_ON in vmstat_update because the work item might have been
sleeping during the idle period and see the cpu_stat_off updated after
the wake up. The VM_BUG_ON is therefore misleading and no more
appropriate. Moreover it doesn't really suite any protection from real
bugs because vmstat_shepherd will simply reschedule the vmstat_work
anytime it sees a particular cpu set or vmstat_update would do the same
from the worker context directly. Even when the two would race the
result wouldn't be incorrect as the counters update is fully idempotent.

MIPS: zboot: Avoid useless rebuilds
Add dummy.o to the targets list, and fill targets automatically from
$(vmlinuzobjs) to avoid having to maintain two lists.
When building with XZ compression copy ashldi3.c to the build
directory to use a different object file for the kernel and zboot.
Without this the same object file need to be build with different
flags which cause a rebuild at every run.

"Initial roundup of 4.5 merge window patches
- Remove usage of ib_query_device and instead store attributes in
ib_device struct
- Move iopoll out of block and into lib, rename to irqpoll, and use
in several places in the rdma stack as our new completion queue
polling library mechanism. Update the other block drivers that
already used iopoll to use the new mechanism too.
- Replace the per-entry GID table locks with a single GID table lock
- IPoIB multicast cleanup
- Cleanups to the IB MR facility
- Add support for 64bit extended IB counters
- Fix for netlink oops while parsing RDMA nl messages
- Add support for remote invalidate to the iSER driver (pushed
through the RDMA tree due to dependencies, acknowledged by nab)

MIPS: Move KVM specific opcodes into asm/inst.h
The header arch/mips/kvm/opcode.h defines a few extra opcodes which
aren't in arch/mips/include/uapi/asm/inst.h. There's nothing KVM
specific about them, so lets move them into inst.h where they belong and
delete the header.
Note that mfmcz_op is renamed to mfmc0_op to match the instruction set
manual, and wait_op was already added to inst.h in commit b0a3eae2b943
("MIPS: inst.h: define COP0 wait op"), merged in v3.16-rc1.

MIPS: Break down cacheops.h definitions
Most of the cache op codes defined in cacheops.h are split into a 2-bit
cache identifier, and a 3-bit cache op code which does largely the same
thing semantically regardless of the cache identifier.
To allow the use of these definitions by KVM for decoding cache ops,
break the definitions down into parts where it makes sense to do so, and
add masks for the Cache and Op field within the cache op.
