kernel - VM rework part 16 - Optimization & cleanup pass
* Adjust __exclusive_cache_line to use 128-byte alignment as
per suggestion by mjg. Use this for the global vmstats.
* Add the vmmeter_neg_slop_cnt global, which is a more generous
dynamic calculation verses -VMMETER_SLOP_COUNT. The idea is to
return how often vm_page_alloc() synchronizes its per-cpu statistics
with the global vmstats.
