CK3 tweaks (Credits to Con Kolivas)

* mm-enable_swaptoken_only_when_swap_full.patch:
  The swap token is only useful in conditions of swap thrash, and actually
  worsens the common case by causing more swapping. Make it only have an effect
  when swap is more than half full.

* mm-drop_swap_cache_aggressively.patch:
  While it may be nice to have a copy of pages on swap once written there, the
  more garbage we leave in the swapspace the slower any further writes and
  reads to and from it are. Just free swapcache whenever we can.

* mm-kswapd_inherit_prio-1.patch:
  When kswapd is awoken due to reclaim by a running task, set the priority of
  kswapd to that of the calling task thus making memory reclaim cpu activity
  affected by nice level.

* hz-default_1000.patch:
  Set default HZ to 1000 which is what most desktop users should still be using.

* hz-no_default_250.patch:
  Make 250HZ not be the default to discourage desktop users from choosing this
  option since 1000 will provide better latencies with only miniscule amounts
  of extra overhead and power consumption.

* preempt-desktop-tune.patch:
  Enable preempt by default and make people steer away from voluntary.
