    x86/mm: Always enable CONFIG_DEBUG_RODATA and remove the Kconfig option · 9ccaf77c
    Kees Cook authored
    This removes the CONFIG_DEBUG_RODATA option and makes it always enabled.
    
    This simplifies the code and also makes it clearer that read-only mapped
    memory is just as fundamental a security feature in kernel-space as it is
    in user-space.
