From: zhong jiang <redacted> I think that CONT_PTE_SHIFT is more reasonable even if they are some value. and the patch is not any functional change.
This may be the case for 64k pages, but not for 16k pages, and I actually think add_default_hugepagesz() could be made unconditional, given that both 64k on 4k kernels and 2 MB on 16k kernels are useful hugepage sizes that are not otherwise available by default.
