[PATCH v2] jump-label: initialize jump-label subsystem somewhat later

[PATCH v2] jump-label: initialize jump-label subsystem somewhat later

[David Daney]

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 trap_init().

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

Difference from v1: Move jump_label_init() up one so it is now before
                    mm_init() instead of after it.
