Bandwidth code was being used as test link rate. Fix this by converting
bandwidth code to test link rate
Do not reset voltage and pre-emphasis level during IRQ HPD attention

dump_unreclaimable_slab() acquires the slab_mutex first,
and it won't remove any slab_caches list entry when
itering the slab_caches lists.
Thus, we do not need list_for_each_entry_safe here,
which is against removal of list entry.

Thanks a lot for the comments,

hot-plugging.
So I submitted V3 patch for you reviewing :)

Unfortunately, in working these up, I realized the heap-helpers
