arm: ptdump: rename CONFIG_DEBUG_WX to CONFIG_ARM_DEBUG_WX
Patch series "mm: ptdump: Refactor CONFIG_DEBUG_WX and check_wx_pages
debugfs attribute", v2.
This series refactors CONFIG_DEBUG_WX for the 5 architectures implementing
CONFIG_GENERIC_PTDUMP
First rename stuff in ARM which uses similar names while not implementing
CONFIG_GENERIC_PTDUMP.
Then define a generic version of debug_checkwx() that calls
ptdump_check_wx() when CONFIG_DEBUG_WX is set. Call it immediately after
calling mark_rodata_ro() instead of calling it at the end of every
mark_rodata_ro().
Then implement a debugfs attribute that can be used to trigger a W^X test
at anytime and regardless of CONFIG_DEBUG_WX
This patch (of 5):
CONFIG_DEBUG_WX is a core option defined in mm/Kconfig.debug
To avoid any future conflict, rename ARM version into CONFIG_ARM_DEBUG_WX.
