jump label: Make arch_jump_label_text_poke_early() optional
Some archs do not need to do anything special for jump labels on startup (like MIPS). This patch adds a weak function stub for arch_jump_label_text_poke_early(); Cc: Jason Baron <jbaron@redhat.com> Cc: David Miller <davem@davemloft.net> Cc: David Daney <ddaney@caviumnetworks.com> Suggested-by: Thomas Gleixner <tglx@linutronix.de> LKML-Reference: <1286218615-24011-2-git-send-email-ddaney@caviumnetworks.com> LKML-Reference: <20101015201037.703989993@goodmis.org> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
