#     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")

WARNING: vmlinux.o(.text+0x40e): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:.early_setup()
The function start_here_multiplatform() references
the function __init .early_setup().
This is often because start_here_multiplatform lacks a __init 
annotation or the annotation of .early_setup is wrong.
