Sorry, I should have looked at these properly when they went past in
May, but obviously I missed them.

They mostly look ok.  I'm a bit confused on 2/6 though - it seems the
new powerpc alloc_bootmem_huge_page() function is specific to the 16G
gigantic pages.  But can't that function also get called for the
normal 16M hugepages depending on how the hugepage pool is
initialized.

Or am I missing something (wouldn't surprise me given my brain's
sluggishness today)?
