Subject: [PATCH] mm, gup: fix typo in gup_p4d_range()

Message-ID: <20170313052213.11411-1-kirill.shutemov@linux.intel.com> (raw)
gup_p4d_range() should call gup_pud_range(), not itself.

Reported-by: Chris Packham <chris.packham@alliedtelesis.co.nz>
Fixes: c2febafc6773 ("mm: convert generic code to 5-level paging")
