Date: Sun, 15 Feb 2015 16:27:05 +0800 From: Wang Nan <wangnan0@...wei.com> To: <linux@....linux.org.uk> CC: <rostedt@...dmis.org>, <lizefan@...wei.com>, <linux-arm-kernel@...ts.infradead.org>, <linux-kernel@...r.kernel.org>, <x86@...nel.org> Subject: [RFC PATCH 1/3] early kprobes: ARM: add definition for vmlinux.lds use. This patch defines MAX_OPTINSN_SIZE, MAX_INSN_SIZE and KPROBE_OPCODE_SIZE for ARM for vmlinux.lds.S use. These macros are originally defined in kprobes.h, which are unable to be used in vmlinux.lds.
