Subject: [PATCH] mm/hugeltb: fix renaming of PF_MEMALLOC_NOCMA to PF_MEMALLOC_PIN

From: Mike Rapoport <rppt@...ux.ibm.com>

The renaming of PF_MEMALLOC_NOCMA to PF_MEMALLOC_PIN missed one occurrence
in mm/hugetlb.c which causes build error:

  CC      mm/hugetlb.o
mm/hugetlb.c: In function ‘dequeue_huge_page_node_exact’:
mm/hugetlb.c:1081:33: error: ‘PF_MEMALLOC_NOCMA’ undeclared (first use in this function); did you mean ‘PF_MEMALLOC_NOFS’?
  bool pin = !!(current->flags & PF_MEMALLOC_NOCMA);
                                 ^~~~~~~~~~~~~~~~~
                                 PF_MEMALLOC_NOFS
mm/hugetlb.c:1081:33: note: each undeclared identifier is reported only once for each function it appears in
scripts/Makefile.build:273: recipe for target 'mm/hugetlb.o' failed
make[2]: *** [mm/hugetlb.o] Error 1
