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.
