Subject: x86/mm: drop order parameter from free_pagetable()
Date: Thu, 16 Jul 2026 16:51:00 +0200

Patch series "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 2)", v2.

Let's remove the remaining pieces of CONFIG_HAVE_BOOTMEM_INFO_NODE,
performing some smaller cleanups around freeing of reserved vmemmap pages
on the way.


This patch (of 10):

All callers pass 0, so let's drop the parameter.
