Currently, HPAGE_PMD_* constans rely on PMD_SHIFT regardless of
CONFIG_TRANSPARENT_HUGEPAGE. PMD_SHIFT is not defined everywhere (e.g.
arm nommu case).
It means we can't use anything like this in generic code:
if (PageTransHuge(page))
zero_huge_user(page, 0, HPAGE_PMD_SIZE);
else
clear_highpage(page);
For !THP case, PageTransHuge() is 0 and compiler can eliminate
zero_huge_user() call. But it still need to be valid C expression, means
HPAGE_PMD_SIZE has to expand to something compiler can understand.
Previously, HPAGE_PMD_* were defined to BUILD_BUG() for !THP. Let's come
back to it.

We've done this sort of thing before and it blew up. We do want to be
able to use things like HPAGE_PMD_foo in global-var initialisers and
definitions, but the problem is that BUILD_BUG() can't be used outside
functions. For example,

I don't see how it's a blocker. For global variables, we will have to use
#ifdefs, but the approach is still useful for in-function code.

OK. Current mainline uses BUILD_BUG() here, so I guess the change
won't break anything. Yet.
