Subject: [PATCH v2 0/6] mm/hugetlb: Fix commandline parsing behavior for invalid hugepagesize

Current code fails to ignore the 'hugepages=' parameters when unsupported
hugepagesize is specified. With this patchset, introduce new architecture
independent routine hugetlb_bad_size to handle such command line options.
And then call it in architecture specific code.

Changes since v1:
	- Separated different architecture specific changes in different
	  patches
	- CC'ed all arch maintainers

Vaishali Thakkar (6):
  mm/hugetlb: Introduce hugetlb_bad_size
  arm64: mm: Use hugetlb_bad_size
  metag: mm: Use hugetlb_bad_size
  powerpc: mm: Use hugetlb_bad_size
  tile: mm: Use hugetlb_bad_size
  x86: mm: Use hugetlb_bad_size
