[Bug kprobes/4531] systemtap tests fail produce kernel oops on some configs of 2.6.22-rc2 kernel

CONFIG_DEBUG_RODATA=y has been there in Fedora kernels for some time.
AFAICT, because CONFIG_HOTPLUG_CPU is set it's only getting applied to
_etext..__end_rodata, which does not include the code sections.  It still seems
odd, since I would expect num_cpus_possible to return 1 on some machines anyway.
 Also, the i386 code is similar and I would expect it to be write-protecting the
text for num_possible_cpus()==1 too.  So there is something else going on here.
