Subject[PATCH] jump-label: initialize jump-label subsystem somewhat later
Date
From: David Daney <david.daney@cavium.com>

commit 97ce2c88f9ad42e3c60a9beb9fca87abf3639faa breaks MIPS.

The jump-lable initialization does I-Cache flushing after modifying
code. On MIPS this is done by calling through the function pointer
flush_icache_range(). This function pointer is initialized mm_init().

As things stand, we cannot be calling jump_label_init() until after
mm_init() completes, so we move the call down to satisfy this
constraint.
