Subject: [PATCH 4.11 023/150] sparc/mm/hugepages: Fix setup_hugepagesz for invalid values.

4.11-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit f322980b74a15e08f8c70a34a5864ecdbf957251 ]

hugetlb_bad_size needs to be called on invalid values.  Also change the
pr_warn to a pr_err to better align with other platforms.
