Caused by commit 6349601ed3e1 ("net: mvpp2: set dma mask and coherent
dma mask on PPv2.2"), which seems irrelevant for 4.4 since PPv2.2
support was added in 4.12 per upstream commit fc5e1550e5c3 ("net: mvpp2:
finally add the PPv2.2 compatible string").

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.
