We never get to allocate 1GB pages when mapping the vmemmap range.
Drop the dead code both for the aligned and unaligned cases and leave
only the direct map handling.
I was hoping to seem some more meat in this changelog, possibly some of
what David Hildenbrand said in the v4 thread about this patch.
Basically, we don't have code to allocate 1G mappings because it isn't
clear that it would be worth the complexity, and it might also waste memory.

I'm fine with the code, but I would appreciate a beefed-up changelog:

Acked-by: Dave Hansen <dave.hansen@linux.intel.com>
Since I had to do another pass to fix up some compilaton errors,
I added a bit more of explanation in that regard.

Thanks!
