    KVM: PPC: Book3S HV: Use bitmap of active threads rather than count · 7d6c40da
    Paul Mackerras authored
    Currently, the entry_exit_count field in the kvmppc_vcore struct
    contains two 8-bit counts, one of the threads that have started entering
    the guest, and one of the threads that have started exiting the guest.
    This changes it to an entry_exit_map field which contains two bitmaps
    of 8 bits each.  The advantage of doing this is that it gives us a
    bitmap of which threads need to be signalled when exiting the guest.
    That means that we no longer need to use the trick of setting the
    HDEC to 0 to pull the other threads out of the guest, which led in
    some cases to a spurious HDEC interrupt on the next guest entry.
