[PATCH v5 21/27] x86/mm: set ARCH_WANT_HUGETLB_VMEMMAP_PREINIT
Posted by Frank van der Linden 9 months, 3 weeks ago
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.
