* pager.h (pager_min_alloc_before_next_collect): New declaration.
(pager_collect_needed): Only collect if AVAILABLE_PAGES >
PAGER_LOW_WATER_MARK and PAGER_MIN_ALLOC_BEFORE_NEXT_COLLECT > 0.
(pager_collect_needed): Don't include the dirty, non-discardable
pages when consider if a collection is required.
* pager.c (pager_min_alloc_before_next_collect): New variable.
(pager_collect): If we don't collect enough pages to exceed the
high water mark, set PAGER_MIN_ALLOC_BEFORE_NEXT_COLLECT to
two-thirds the available pages.
* memory.c (memory_frame_allocate): On success, decrement
PAGER_MIN_ALLOC_BEFORE_NEXT_COLLECT.

* pager.h: Include "memory.h", "zalloc.h", and "object.h".
(pager_collect): Take an additional argument goal and return an
integer.
(PAGER_LOW_WATER_MARK): New macro.
(PAGER_HIGH_WATER_MARK): Likewise.
(pager_collect_needed): New function.
(pager_query): Likewise.
* pager.c (LOW_WATER_MARK): Don't define.
(HIGH_WATER_MARK): Likewise.
(is_clean): New function.
(reclaim_from): New function. Broken out of pager_collect.
Correctly update statistics.
(pager_collect): Take an additional argument goal and return an
integer. Rewrite victim selection implementation.
* memory.c (memory_frame_allocate): Call page_query. If zalloc
fails, take from the available list. Add asserts. Don't clear
memory if we get memory from zalloc.

* activity.h (struct activity): Add fields eviction_clean and
eviction_dirty. Improve comments.
(activity_charge): Change asserts to account for unsignedness.
* activity.c (activity_destroy): Move all objects owned by VICTIM
to its parent.
(activity_deprepare): Add additional asserts.
(do_activity_dump): Don't assert that ACTIVITY->FRAMES_LOCAL is
the sum of the items on ACTIVITY's LRU lists.
* object.h (struct object_desc): Add fields eviction_candidate,
live, laundry_node and available_node. Make priority_node a union
with activity_node, which replaces activity_lru. Remove field
global_lru.
(object_activity_lru): Rename this list class...
(activity_lru): ... to this. Update users.
(object_global_lru): Don't generate this list class.
(eviction): Generate new list class.
(available): Likewise.
(laundry): Likewise.
(global_active): Remove declaration.
(global_inactive_dirty): Likewise.
(global_inactive_clean): Likewise.
(disowned): Likewise.
(laundry): New declaration.
(available): Likewise.
(memory_object_destroy): Likewise.
(object_desc_disown_simple): Remove declaration.
(object_disown_simple): Remove function.
(object_desc_disown): Likewise.
(object_disown): Likewise.
(object_desc_claim): Take additional parameter update_accounting.
Update users.
(object_claim): Likewise.
(object_desc_unmap): New function.
(object_age): Likewise.
(objects_folio_offset): Likewise.
(objects_folio): Likewise.
(object_free): Implement in terms of the above two functions.
* object.c (global_active): Remove variable.
(global_inactive_dirty): Likewise.
(global_inactive_clean): Likewise.
(disowned): Likewise.
(laundry): New variable.
(available): Likewise.
(memory_object_alloc): Initialize ODESC to 0. Call
object_desc_claim to attach it to the relevant lists. Assert that
ODESC->LIVE is 0. Set ODESC->LIVE to 1.
(memory_object_destroy): Remove static qualifier. Require that
LRU_LOCK be held on entry. Update users. Use object_desc_claim
to disconnect DESC from any lists to which it is attached. Don't
call memory_frame_free, that is now the caller's responsibility.
Update users. Set DESC->LIVE to 0.
(folio_free): Don't disown the folio header.
(folio_object_alloc): Call memory_frame_free to really free the
memory.
(object_desc_disown_simple): Remove function.
(object_desc_disown_): Likewise.
(object_desc_claim): Take additional parameter update_accounting.
If true, update the relevant activities' accounting information.
Update connect and disconnect code. Only add an object to one of
the priority tree and the lru lists, but not both.
* viengoos.c (system_task_load): After allocating the
root activity, have the root activity claim it and FOLIO.
* ager.c: Include "zalloc.h".
(AGE_DELTA): Don't define.
(ager_loop): Rewrite to walk the object descriptors sequentially
rather than following a linked list. Update object list
connection and disconnection code.
* pager.h: New file.
* pager.c: Likewise.
* Makefile.am (viengoos_SOURCES): Add pager.h and pager.c.
* memory.h (struct activity): Add forward.
(memory_frame_allocate): Take additional parameter activity.
Return a uintptr_t instead of an l4_word_t. Update users.
* memory.c: Include "pager.h" and "activity.h".
(memory_grab): Always get base page sized pages.
(memory_frame_allocate): Take additional parameter activity.
Return a uintptr_t instead of an l4_word_t. If zalloc fails,
check AVAILABLE_LIST. If nothing is applicable, call
pager_collect and try again.
* t-environment.h (pager_collect): New function.
