On most OMAP3 platforms, the twl4030 IRQ line is connected to the
SYS_NIRQ line on OMAP. Add another DTS include file
(twl4030_omap3.dtsi) for boards that hook up the twl4030 this way
to include.
This allows RTC wake from off-mode to work again on OMAP3-based
platforms with twl4030. Tested on 3530/Beagle, 3730/Beagle-xM,
3530/Overo, 3730/Overo-STORM.

Using the gpio-keys bindings, configure the user button on Beagle

ensure the GPIO pin is mux'd correctly and has IO ring wakeups enabled,

The uevm is the only official board supported for the OMAP5 soc
in mainline. The existent sevm platform will no more be supported.
Hence cleaning up the board dts file to have only the data
required for uevm.
Renaming the board dts file and adding the following cleanups.
* There are no devices connected on I2C 2,3,4 buses. So remove
the pinmux data for the same.
* OMAP5432 and DDR3 memory is used in the uevm. Temperature polling
is not supported with DDR3 memories. Because of DDR3 phy limitation
the voltage change across DVFS and all shadow registers for DVFS on
DDR3 is not supported. Hence the emif kernel driver is not required,
so removing the DDR3 device file and emif nodes for uevm.
* Keypad is not supported on uevm. So remove the device node.

When replaying interrupts (as a result of the interrupt occurring
while soft-disabled), in the case of the decrementer, we are exclusively
testing for a pending timer target. However we also use decrementer
interrupts to trigger the new "irq_work", which in this case would
be missed.
This change the logic to force a replay in both cases of a timer
boundary reached and a decrementer interrupt having actually occurred
while disabled. The former test is still useful to catch cases where
a CPU having been hard-disabled for a long time completely misses the
interrupt due to a decrementer rollover.

Normally, the kernel emulates a few instructions that are unimplemented
on some processors (e.g. the old dcba instruction), or privileged (e.g.
mfpvr). The emulation of unimplemented instructions is currently not
working on the PowerNV platform. The reason is that on these machines,
unimplemented and illegal instructions cause a hypervisor emulation
assist interrupt, rather than a program interrupt as on older CPUs.
Our vector for the emulation assist interrupt just calls
program_check_exception() directly, without setting the bit in SRR1
that indicates an illegal instruction interrupt. This fixes it by
making the emulation assist interrupt set that bit before calling
program_check_interrupt(). With this, old programs that use no-longer
implemented instructions such as dcba now work again.

... and so on
__ppc64_runlatch_on() is called from RUNLATCH_ON in the exception entry
path. At that point the irq state is not consistent, ie. interrupts are
hard disabled (by the exception entry), but the paca soft-enabled flag
may be out of sync.
This leads to the local_irq_restore() in trace_graph_entry() actually
enabling interrupts, which we do not want. Because we have not yet
reprogrammed the decrementer we immediately take another decrementer
exception, and recurse.
The fix is twofold. Firstly make sure we call DISABLE_INTS before
calling RUNLATCH_ON. The badly named DISABLE_INTS actually reconciles
the irq state in the paca with the hardware, making it safe again to
call local_irq_save/restore().
Although that should be sufficient to fix the bug, we also mark the
runlatch routines as notrace. They are called very early in the
exception entry and we are asking for trouble tracing them. They are
also fairly uninteresting and tracing them just adds unnecessary
overhead.

The OF code uses irqsafe locks everywhere except in a handful of functions
for no obvious reasons. Since the conversion from the old rwlocks, this
now triggers lockdep warnings when used at interrupt time. At least one
driver (ibmvscsi) seems to be doing that from softirq context.
This converts the few non-irqsafe locks into irqsafe ones, making them
consistent with the rest of the code.

The __vvar_page relocation should actually be listed in S_REL instead
of S_ABS. Oddly, this didn't always cause things to break, presumably
because there are no users for relocation information on 64 bits yet.

Pull MIPS fixes from Ralf Baechle:
"Resurrect Alchemy platforms by invoking the WAIT instructions with
interrupts enabled. This still leaves the race condition between
testing TIF_NEED_RESCHED and the WAIT instruction for Alchemy
platforms which need a different fix than other MIPS platforms. But
at least it gets MIPS platforms flying again.
There are also fixes for two build errors (CONFIG_FTRACE=y with
CONFIG_DYNAMIC_FTRACE=n) and CONFIG_VIRTUALIZATION without CONFIG_KVM"
* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
MIPS: ftrace: Add missing CONFIG_DYNAMIC_FTRACE
MIPS: include: mmu_context.h: Replace VIRTUALIZATION with KVM
MIPS: Alchemy: fix wait function

Pull kvm bugfixes from Gleb Natapov:
"There is one more fix for MIPS KVM ABI here, MIPS and PPC build
breakage fixes and a couple of PPC bug fixes"
* 'fixes' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
kvm/ppc/booke64: Fix lazy ee handling in kvmppc_handle_exit()
kvm/ppc/booke: Hold srcu lock when calling gfn functions
kvm/ppc/booke64: Disable e6500 support
kvm/ppc/booke64: Fix AltiVec interrupt numbers and build breakage
mips/kvm: Use KVM_REG_MIPS and proper size indicators for *_ONE_REG
kvm: Add definition of KVM_REG_MIPS
KVM: add kvm_para_available to asm-generic/kvm_para.h

EE is hard-disabled on entry to kvmppc_handle_exit(), so call
hard_irq_disable() so that PACA_IRQ_HARD_DIS is set, and soft_enabled
is unset.
Without this, we get warnings such as arch/powerpc/kernel/time.c:300,
and sometimes host kernel hangs.
