This patch adds some more elements to the existing PACA dump list
inside a xmon session which can be listed here.
- hmi_event_available
- dscr_default
- vmalloc_sllp
- slb_cache_ptr
- sprg_vdso
- tm_scratch
- core_idle_state_ptr
- thread_idle_state
- thread_mask
With this patch, a typical xmon PACA dump looks something like this.

online = yes
