Subject: [PATCH v2 0/2] move __HAVE_ARCH_PTE_SPECIAL in Kconfig

The per architecture __HAVE_ARCH_PTE_SPECIAL is defined statically in the
per architecture header files. This doesn't allow to make other
configuration dependent on it.

The first patch of this series is replacing __HAVE_ARCH_PTE_SPECIAL by
CONFIG_ARCH_HAS_PTE_SPECIAL defined into the Kconfig files,
setting it automatically when architectures was already setting it in
header file.

The second patch is removing the odd define HAVE_PTE_SPECIAL which is a
duplicate of CONFIG_ARCH_HAS_PTE_SPECIAL.

There is no functional change introduced by this series.

Laurent Dufour (2):
  mm: introduce ARCH_HAS_PTE_SPECIAL
  mm: remove odd HAVE_PTE_SPECIAL
