These patches add support for stolen time functionality. Patch #1 moves the vCPU structure initialisation before the target->init() call to allow early access to the kvm structure from the vCPU during target->init(). Patch #2 modifies the memory layout in arm-common/kvm-arch.h and adds a new MMIO device PVTIME after the RTC region. A new flag is added in kvm-config.h that will be used to control [enable/disable] the pvtime functionality. Stolen time is enabled by default when the host supports KVM_CAP_STEAL_TIME. Patch #3 adds a new command line argument to disable the stolen time functionality(by default is enabled). Changelog since v6: - fix perror number of arguments Changelog since v5: - propagate the error code from the kvm_cpu__setup_pvtime() when the host supports KVM_CAP_STEAL_TIME but if fails to configure it for stolen time functionality.
