#     powerpc/mm: Fix hugetlb page initialization
#     
#     This patch fixes a regression by using correct kernel config variable
#     for HUGETLB_PAGE_SIZE_VARIABLE.
#     
#     Without this huge pages are disabled during kernel boot.
#     [0.309496] hugetlbfs: disabling because there are no supported hugepage sizes
#     
#     Fixes: c5710cd20735 ("powerpc/mm: cleanup HPAGE_SHIFT setup")
