CVS commit: src/sys/uvm

["Andrew Doran" <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Thu Jun 11 22:25:51 UTC 2020

Modified Files:
        src/sys/uvm: uvm_pglist.c

Log Message:
Counter tweaks:

- Don't need to count anonpages+filepages any more; clean+unknown+dirty for
  each kind of page can be summed to get the totals.

- Track the number of free pages with a counter so that it's one less thing
  for the allocator to do, which opens up further options there.

- Remove cpu_count_sync_one(). It has no users and doesn't save a whole lot.
  For the cheap option, give cpu_count_sync() a boolean parameter indicating
  that a cached value is okay, and rate limit the updates for cached values
  to hz.
