Ard Biesheuvel 57efac2f71 arm64: enable CONFIG_DEBUG_RODATA by default ... In spite of its name, CONFIG_DEBUG_RODATA is an important hardening feature for production kernels, and distros all enable it by default in their kernel configs. However, since enabling it used to result in more granular, and thus less efficient kernel mappings, it is not enabled by default for performance reasons. However, since commit 2f39b5f91e ("arm64: mm: Mark .rodata as RO"), the various kernel segments (.text, .rodata, .init and .data) are already mapped individually, and the only effect of setting CONFIG_DEBUG_RODATA is that the existing .text and .rodata mappings are updated late in the boot sequence to have their read-only attributes set, which means that any performance concerns related to enabling CONFIG_DEBUG_RODATA are no longer valid. So from now on, make CONFIG_DEBUG_RODATA default to 'y' Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Mark Rutland <mark.rutland@arm.com> Acked-by: Kees Cook <keescook@chromium.org> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>		2016-03-03 18:14:17 +00:00
