Thanks for this. Seems good to me, with one question inline.

Edit: you missed the update of vmparam.h for 32-bit arm.

sys/vm/vm_page.c
623	Why is this condition different than the others?

Add missing arm vmparam.h updates.

sys/vm/vm_page.c
623	I wanted to avoid adding another `#if MINIDUMP_PAGE_TRACKING && MINIDUMP_STARTUP_PAGE_TRACKING`, so I've moved the `#if MINIDUMP_STARTUP_PAGE_TRACKING` block under the `MINIDUMP_PAGE_TRACKING` block defined on line 598. The condition is still the same, but less verbose.
