Subject: [PATCH] Fix kprobes on ia64


If CONFIG_KPROBES is set, we get the error during build:

kernel/kprobes.c:1057: error: __ksymtab_jprobe_return causes a section
type conflict

This is because ia64 defines a static inline jprobe_return which kprobes
attempts to EXPORT_SYMBOL.

operating system, but compare it to ours.  We can't possibly take such
a retrograde step."
