Subject: hugetlb: fix clear_user_highpage arguments
From: Ralf Baechle <ralf@xxxxxxxxxxxxxx>
The virtual address space argument of clear_user_highpage is supposed to be
the virtual address where the page being cleared will eventually be mapped.
This allows architectures with virtually indexed caches a few clever
tricks. That sort of trick falls over in painful ways if the virtual
address argument is wrong.
