The quilt patch titled

     x86-setup-call-hugetlb_bootmem_alloc-early.patch

Subject: x86/setup: call hugetlb_bootmem_alloc early
Date: Fri, 28 Feb 2025 18:29:21 +0000

Call hugetlb_bootmem_allloc in an earlier spot in setup, after
hugelb_cma_reserve.  This will make vmemmap preinit of the sections
covered by the allocated hugetlb pages possible.
