[Andrew Morton]

The quilt patch titled
     Subject: x86/mm: set ARCH_WANT_HUGETLB_VMEMMAP_PREINIT
has been removed from the -mm tree.  Its filename was
     x86-mm-set-arch_want_hugetlb_vmemmap_preinit.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: x86/mm: set ARCH_WANT_HUGETLB_VMEMMAP_PREINIT
Date: Fri, 28 Feb 2025 18:29:22 +0000

Now that hugetlb bootmem pages are allocated earlier, and available for
section preinit (HVO-style), set ARCH_WANT_HUGETLB_VMEMMAP_PREINIT for
x86_64, so that is can be done.

This enables pre-HVO on x86_64.
