[patch 132/173] mm/hugetlb: suppress wrong warning info when alloc gigantic page

From: Chen Wandun <redacted>
Subject: mm/hugetlb: suppress wrong warning info when alloc gigantic page

If hugetlb_cma is enabled, it will skip boot time allocation when
allocating gigantic page, that doesn't means allocation failure, so
suppress this warning info.
