      arm/xen: fix SMP guests boot · de75abbe
      Vitaly Kuznetsov authored
      Commit 88e957d6 ("xen: introduce xen_vcpu_id mapping") broke SMP
      ARM guests on Xen. When FIFO-based event channels are in use (this is
      the default), evtchn_fifo_alloc_control_block() is called on
      CPU_UP_PREPARE event and this happens before we set up xen_vcpu_id
      mapping in xen_starting_cpu. Temporary fix the issue by setting direct
      Linux CPU id <-> Xen vCPU id mapping for all possible CPUs at boot. We
      don't currently support kexec/kdump on Xen/ARM so these ids always
      match.
      
      In future, we have several ways to solve the issue, e.g.:
      
      - Eliminate all hypercalls from CPU_UP_PREPARE, do them from the
        starting CPU. This can probably be done for both x86 and ARM and, if
        done, will allow us to get Xen's idea of vCPU id from CPUID/MPIDR on
        the starting CPU directly, no messing with ACPI/device tree
        required.
      
      - Save vCPU id information from ACPI/device tree on ARM and use it to
        initialize xen_vcpu_id mapping. This is the same trick we currently
        do on x86.
