Series [v3,1/2] mm/vmemmap/devdax: Fix kernel crash when probing devdax devices | expand

Commit Message

Aneesh Kumar K.V April 12, 2023, 5 a.m. UTC 
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
