mm/hugetlb_vmemmap: rename ARCH_WANT_HUGETLB_PAGE_OPTIMIZE_VMEMMAP
Now we use ARCH_WANT_HUGETLB_PAGE_OPTIMIZE_VMEMMAP config option to indicate devdax and hugetlb vmemmap optimization support. Hence rename that to a generic ARCH_WANT_OPTIMIZE_VMEMMAP Link: https://lkml.kernel.org/r/20230412050025.84346-2-aneesh.kumar@linux.ibm.com Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> Reviewed-by: Muchun Song <songmuchun@bytedance.com> Cc: Joao Martins <joao.m.martins@oracle.com> Cc: Dan Williams <dan.j.williams@intel.com> Cc: Mike Kravetz <mike.kravetz@oracle.com> Cc: Tarun Sahu <tsahu@linux.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

SPARSEMEM_VMEMMAP uses a virtually mapped memmap to optimise
pfn_to_page and page_to_pfn operations. This is the most
efficient option when sufficient kernel resources are available.
