Same test now done w/ rc1-mm2... similar result.
However, instead of pegging 1 virtual cpu in system time, two virtual CPUs on the same core now share the 100% load (so each shows 50% load and 50% idle).
Oprofile shows:
5610635 66.9136 zap_pte_range 711147 8.4813 _raw_spin_trylock 498282 5.9426 unmap_mapping_range 196369 2.3419 add_preempt_count 126243 1.5056 unmap_page_range 111791 1.3332 __bitmap_weight 96284 1.1483 page_address 88998 1.0614 _raw_spin_unlock
And I'm attaching the sysrq dump
