From c9093486f283c3447439f234eb0124129e8e7834 Mon Sep 17 00:00:00 2001 From: Anshuman Khandual Date: Fri, 21 Jun 2019 21:39:18 +0530 Subject: [PATCH] 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.
