98acdbe4cf [ARM] pxa: define zeus_power_off() only when CONFIG_PM enabled
Add some safety check for CONFIG_PM around zeus_power_off(). Without
it linking can fail like this:

arch/arm/mach-pxa/built-in.o: In function `zeus_power_off':

cfab57e0e4 [ARM] pxa: enable check_scoop_reg() only if CONFIG_PM is set.
This function gets only called from scoop_suspend() and scoop_resume() which are
only built in if we have CONFIG_PM set. Make it the same for check_scoop_reg().

This fixes the following warning:
arch/arm/common/scoop.c:143: warning: ‘check_scoop_reg’ defined but not used

00dd8027b9 [ARM] locomo: remove unused IRQs and avoid unnecessary cascade
IRQ_LOCOMO_* are never used elsewhere, remove these definitions. As well
as the cascade of these IRQs. IRQ_LOCOMO_*_BASE changed to IRQ_LOCOMO_*.

IRQ_LOCOMO_LT and IRQ_LOCOMO_SPI are likely to be used in a same way as
IRQ_LOCOMO_KEY.

IRQ_LOCOMO_GPIO and the demultiplex handler should really be living
somewhere else.

e54cfa97a9 KVM: Fix emulate_sys[call, enter, exit]()'s fault handling
This patch fixes emulate_syscall(), emulate_sysenter() and
emulate_sysexit() to handle injected faults properly.

Even though original code injects faults in these functions,
we cannot handle these unless we use the different return
value from the UNHANDLEABLE case. So this patch use X86EMUL_*
codes instead of -1 and 0 and makes x86_emulate_insn() to
handle these propagated faults.

Be sure that, in x86_emulate_insn(), goto cannot_emulate and
goto done with rc equals X86EMUL_UNHANDLEABLE have same effect.

This patch injects page fault when reading descriptor in

Effects of this injection: This function is used by
kvm_load_segment_descriptor() which is necessary for the
following instructions:

 - mov seg,r/m16
 - jmp far
 - pop ?s

This patch makes it possible to emulate the page faults
generated by these instructions. But be sure that unless
we change the kvm_load_segment_descriptor()'s ret value

1871c6020d KVM: x86 emulator: fix memory access during x86 emulation
Currently when x86 emulator needs to access memory, page walk is done with
broadest permission possible, so if emulated instruction was executed
by userspace process it can still access kernel memory. Fix that by
providing correct memory access to page walker during emulation.

a004475567 KVM: x86 emulator: Add Virtual-8086 mode of emulation
For some instructions CPU behaves differently for real-mode and
virtual 8086. Let emulator know which mode cpu is in, so it will
not poke into vcpu state directly.

daf5e27109 KVM: ppc/booke: Set ESR and DEAR when inject interrupt to guest
Old method prematurely sets ESR and DEAR.
Move this part after we decide to inject interrupt,
which is more like hardware behave.

4b7bb92100 KVM: ia64: destroy ioapic device if fail to setup default irq routing
If KVM_CREATE_IRQCHIP fail due to kvm_setup_default_irq_routing(),
ioapic device is not destroyed and kvm->arch.vioapic is not set to
NULL, this may cause KVM_GET_IRQCHIP and KVM_SET_IRQCHIP access to
unexcepted memory.
