Subject: [PATCH 0/8] thp: transparent hugepages on s390

This patch series adds support for transparent hugepages on s390.
Small changes to common code are necessary with regard to a different
pgtable_t, tlb flushing and kvm behaviour on s390, see patches 2 to 4.
Also, (x86) Kconfig is touched by patch 1.

Changes since RFC v2:
  [PATCH 1/8] introduce HAVE_ARCH_TRANSPARENT_HUGEPAGE in Kconfig
  [PATCH 2/8] rename pgtable_deposit/withdraw
  [PATCH 6/8] rename pgtable_deposit/withdraw
  [PATCH 8/8] rename pgtable_deposit/withdraw

Gerald Schaefer (8):
  thp, x86: introduce HAVE_ARCH_TRANSPARENT_HUGEPAGE in Kconfig
  thp: remove assumptions on pgtable_t type
  thp: introduce pmdp_invalidate()
  thp: make MADV_HUGEPAGE check for mm->def_flags
  thp, s390: thp splitting backend for s390
  thp, s390: thp pagetable pre-allocation for s390
  thp, s390: disable thp for kvm host on s390
  thp, s390: architecture backend for thp on s390
