Subject: mips/kprobes: export kprobe_fault_handler()
Generic kprobe_page_fault() calls into kprobe_fault_handler() which must
be available with and without CONFIG_KPROBES. There is one stub
implementation for !CONFIG_KPROBES. For CONFIG_KPROBES all subscribing
archs must provide a kprobe_fault_handler() definition. Currently mips
has an implementation which is defined as 'static inline'. Make it
available for generic kprobes to comply with the above new requirement.
