Implement the PSCI specification (ARM DEN 0022A) to control
virtual CPUs being powered on or off.
PSCI/KVM is detected using the KVM_CAP_ARM_PSCI capability.
A virtual CPU can now be initialized
to run
the VCPU must check if there's a pending MMIO load and perform the write
after userspace has made the data available.

Guys,
I've once more updated the branches for KVM/arm64
- kvm-arm/pre-arm64: kvm-arm-master as of today + the cleanup branch +
some basic perf support
- arm64/soc-armv8-model: Catalin Marinas' arm64 branch
- arm64/psci: Implementation of PSCI for the above
- arm64/perf: host/guest
to have verxpress support.
There is no need for a platforms directory any more. The vexpress support is
now just a configuration option.
Thanks,
Pranav
Cheers,
M.

Here's a number of patches to cope with the churn that occured in
kvm-next, and breaks the compilation in next-20130215.
No big deal, just regular breakage...
Tested on TC2.

v8 is capable of invalidating Stage-2 by IPA, but v7 is not.
Change kvm_tlb_flush_vmid() to take an IPA parameter, which is
then ignored by the invalidation code (and nuke the whole TLB
as it always did).
This allows v8 to implement a more optimized strategy.

The ARM ARM says that HPFAR reports bits [39:12] of the faulting
IPA, and we need to complement it with the bottom 12 bits of the
faulting VA.
This is always 12 bits, irrespective of the page size. Makes it
clearer in the code.

On ARM, where we can have an identity mapping between kernel and HYP,
the macros are without any effect.

Instead of hardcoding the maximum MMIO access to be 4 bytes,
compare it to sizeof(unsigned long), which will do the
right thing on both 32 and 64bit systems.
