2013-06-26	ARM: KVM: Don't handle PSCI calls via SMC	Dave P Martin
	Currently, kvmtool unconditionally declares that HVC should be used to call PSCI, so the function numbers in the DT tell the guest nothing about the function ID namespace or calling convention for SMC. We already assume that the guest will examine and honour the DT, since there is no way it could possibly guess the KVM-specific PSCI function IDs otherwise. So let's not encourage guests to violate what's specified in the DT by using SMC to make the call.

2013-01-23	KVM: ARM: Power State Coordination Interface implementation	Marc Zyngier
	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 in a "powered off" state, using the KVM_ARM_VCPU_POWER_OFF feature flag. The guest can use either SMC or HVC to execute a PSCI function.
