Subject: Allow DEBUG_RODATA and KPROBES to co-exist
X-Git-Tag: v2.6.22-rc6~40

Allow DEBUG_RODATA and KPROBES to co-exist

Do not mark the kernel text read only if KPROBES is in the kernel;
kprobes needs to hot-patch the kernel text to insert it's
instrumentation.

In this case, only mark the .rodata segment as read only.
