Merge tag 'rodata-v4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull rodata updates from Kees Cook: "This renames the (now inaccurate) DEBUG_RODATA and related SET_MODULE_RONX configs to the more sensible STRICT_KERNEL_RWX and STRICT_MODULE_RWX" * tag 'rodata-v4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: arch: Rename CONFIG_DEBUG_RODATA and CONFIG_DEBUG_MODULE_RONX arch: Move CONFIG_DEBUG_RODATA and CONFIG_SET_MODULE_RONX to be common
