[PATCH] mm/huge_memory: Clean up typo when copying user highpage

Hi Andrea

When copying user highpage, the PAGE_SHIFT in the third parameter is a typo,
I think, and is replaced with PAGE_SIZE.

When configuring transparent hugepage, it depends on x86 and MMU.
Would you please tippoint why other archs with MMU, say MIPS, are masked out?

Thanks
