[RFC PATCH 0/5] PSCI system off and reset for KVM ARM/ARM64

[Anup Patel]

The Power State and Coordination Interface (PSCI) specification defines
SYSTEM_OFF and SYSTEM_RESET functions for system poweroff and reboot.

This patchset adds:
1. Emulation of PSCI SYSTEM_OFF and SYSTEM_RESET functions in 
   KVM ARM/ARM64 by forwarding them to user space (QEMU or KVMTOOL)
2. System poweroff and reboot using PSCI for ARM/ARM64 kernel

Anup Patel (5):
  ARM/ARM64: KVM: Update user space API header for PSCI emulation
  ARM/ARM64: KVM: Forward PSCI SYSTEM_OFF and SYSTEM_RESET to user
    space
  KVM: Add documentation for KVM_EXIT_PSCI exit reason
  ARM: psci: Add support for system reboot and poweroff
  ARM64: psci: Add support for system reboot and poweroff
