 * struct ps3_bmp - a per cpu irq status and mask bitmap structure

 * @unused_1:
 * @mask: 256 bit mask bitmap indexed by plug
 * @unused_2:
 * @lock:
 * @ipi_debug_brk_mask:
 *
 * The HV mantains per SMT thread mappings of HV outlet to HV plug on
 * behalf of the guest.  These mappings are implemented as 256 bit guest
 * supplied bitmaps indexed by plug number.  The addresses of the bitmaps
 * are registered with the HV through lv1_configure_irq_state_bitmap().
 * The HV requires that the 512 bits of status + mask not cross a page
 * boundary.  PS3_BMP_MINALIGN is used to define this minimal 64 byte
 * alignment.
 *
 * The HV supports 256 plugs per thread, assigned as {0..255}, for a total
 * of 512 plugs supported on a processor.  To simplify the logic this
 * implementation equates HV plug value to Linux virq value, constrains each
 * interrupt to have a system wide unique plug number, and limits the range
 * of the plug values to map into the first dword of the bitmaps.  This
 * gives a usable range of plug values of  {NUM_ISA_INTERRUPTS..63}.  Note
 * that there is no constraint on how many in this set an individual thread
 * can acquire.
