The timing results for 8-10 buildworlds, with and without this patch. Without:
Fri, Nov 29
Drop the vm_page_iter_free() parts committed elsewhere.
Thu, Nov 28
Add a panic when a page duplication is found. Match param names between definition and declaration.
Comments in vm_reserv.c need to be updated to reflect this change.
Wed, Nov 27
Define inline pctrie_setpop() to flip popmap bits from 0 to 1 and assert that they have become set. Use it in 3 places.
Tue, Nov 26
Mon, Nov 25
Remove changes to vm_page_iter_remove.
Sun, Nov 24
Pass the removed page to vm_page_iter_remove, and functions that use it. Update comments. Reorder declarations.
Apply suggestions from feedback on D46724 to improve performance.
Sat, Nov 23
Drop the fix that @kib has committed separately.
Thu, Nov 21
Drop length argument to cdev_mgtdev_pager_free_pages().
Fix typo in tegra_bo.c.
Wed, Nov 20
Mon, Nov 18
Use vm_radix_iter_found in swap_pager.c. Tweak the pctrie.h implement to avoid a pointless null check.
Sun, Nov 17
Avoid the object != NULL check in vm_page_iter_free.
Sat, Nov 16
alc update 11/16.
Fri, Nov 15
Drop the bool argument from vm_page_free_toq. Turn vm_page_free_toq into a wrapper for the real implementation function, to which it passes 'true' as the bool argument.
Update some comments.
Thu, Nov 14
Remove changes to subr_pctrie.c. Pass the iterator to vm_page_rename() to allow the page to be removed with the iterator and the appropriate page number.
Wed, Nov 13
Rename vm_page_object_remove.
Rearrange into vm_page_iter_remove and vm_page_iter_free iter-based substitutes for the iter-less equivalents.
Sat, Nov 9
Performance test:
Ran 12 buildworlds, without and with this change, on an amd64 machine to verify it did not harm performance there.

Rebase. Undo some function reordering that makes this reviewer easier, even if it preserves some odd ordering.

Refresh.
If you're inserting batch [a,b,...,y.z], and if you began by inserting a and z with normal iter-insert, then your BATCH_SPLIT case would never happen and some of the complexity of batch_insert could be reduced. True or false?

In D47036, I put it after vm_radix_iter_step, mostly because PCTRIE_ITER_LOOKUP_LE comes shortly after PCTRIE_ITER_STEP_GE in pctrie.h. 'step' and 'jump' are built on top of lookup_ge, so I kept them grouped with lookup_ge.

Tweak the first loop in pctrie_iter_lookup_le to make it 2 whole bytes smaller. And, for the _ge version, one byte smaller.
Drop ..._iter_lookup_lt().
