arch/powerpc/mm/hugetlbpage.c: In function 'add_huge_page_size': arch/powerpc/mm/hugetlbpage.c:840:2: error: implicit declaration of function 'radix_enabled'
Caused by commit 17cd5e81ded7 ("powerpc/mm/hugetlb: Filter out hugepage size not supported by page table layout"). It is introduced in 4.7 in upstream commit 566ca99af026 ("powerpc/mm/radix: Add dummy radix_enabled()") and not properly turned on until upstream commit a8ed87c92adf ("powerpc/mm/radix: Add MMU_FTR_RADIX"). I am going to assume from the fact there is a lot of MMU work after this and the wording of the Kconfig entry that this is probably not suitable fo a stable backport.
Now dropped from the 4.4.y queue as well, thanks to both of you for this work.
Let me go do some more -rc releases now...
thanks,
