v2 of the series for doing PSCI calls in userspace.

Changes since v1 [*]:
 - Avoid successive calls to KVM_ARM_VCPU_FINALIZE (Joey)
 - Clear the 'paused' state from calling vCPU in kvm_cpu__continue_vm()
   (Shaoqin)

Oliver Upton (20):
  update_headers: Use a list for arch-generic headers
  update_headers: Add missing entries to list of headers to copy
  Copy 64-bit alignment attrtibutes from Linux 6.4-rc1
  Update headers with Linux 6.4-rc1
  Import arm-smccc.h from Linux 6.4-rc1
  aarch64: Copy cputype.h from Linux 6.4-rc1
  arm: Stash kvm_vcpu_init for later use
  arm: Use KVM_SET_MP_STATE ioctl to power off non-boot vCPUs
  aarch64: Expose ARM64_CORE_REG() for general use
  arm: Generalize execution state specific VM initialization
  Add helpers to pause the VM from vCPU thread
  aarch64: Add support for finding vCPU for given MPIDR
  aarch64: Add skeleton implementation for PSCI
  aarch64: psci: Implement CPU_SUSPEND
  aarch64: psci: Implement CPU_OFF
  aarch64: psci: Implement CPU_ON
  aarch64: psci: Implement AFFINITY_INFO
  aarch64: psci: Implement MIGRATE_INFO_TYPE
  aarch64: psci: Implement SYSTEM_{OFF,RESET}
  aarch64: smccc: Start sending PSCI to userspace
