dlg [Fri, 16 Jun 2017 01:55:45 +0000 (01:55 +0000)]
add garbage collection of unused lists percpu cached items.

the cpu caches in pools amortise the cost of accessing global
structures by moving lists of items around instead of individual
items. excess lists of items are stored in the global pool struct,
but these idle lists never get returned back to the system for use
elsewhere.

this adds a timestamp to the global idle list, which is updated
when the idle list stops being empty. if the idle list hasn't been
empty for a while, it means the per cpu caches arent using the idle
entries and they can be recovered. timestamping the pages prevents
recovery of a lot of items that may be used again shortly. eg, rx
ring processing and replenishing from rate limited interrupts tends
to allocate and free items in large chunks, which the timestamping
smooths out.

gc'ed lists are returned to the pool pages, which in turn get gc'ed
back to uvm.

split returning an item to the pool pages out of pool_put as pool_do_put.

this lets pool_cache_list_put return items to the pages. currently,
if pool_cache_list_put is called while the per cpu caches are
enabled, the items on the list will put put straight back onto
another list in the cpu cache. this also avoids counting puts for
these items twice. a put for the items have already been coutned
when the items went to a cpu cache, it doesnt need to be counted
again when it goes back to the pool pages.

another side effect of this is that pool_cache_list_put can take
the pool mutex once when returning all the items in the list with
pool_do_put, rather than once per item.
