So I understand this series has more "readability" value and I'm fine with this change but I wonder if you really would want to make something depend on it or make this de-configurable. PTE special is really a fundamental construct - e.g. it is used for anon mapped pages where zero page has been wired up etc... -Vineet > This series is moving the __HAVE_ARCH_PTE_SPECIAL into the Kconfig files, > setting it automatically when architectures was already setting it in > header file. > > There is no functional change introduced by this series.
