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
