Adam Litke 72fad7139b hugetlb: handle write-protection faults in follow_hugetlb_page
The follow_hugetlb_page() fix I posted (merged as git commit
5b23dbe817) missed one case.  If the pte is
present, but not writable and write access is requested by the caller to
get_user_pages(), the code will do the wrong thing.  Rather than calling
hugetlb_fault to make the pte writable, it notes the presence of the pte
and continues.

This simple one-liner makes sure we also fault on the pte for this case.
Please apply.
