Subject: [PATCH 4.20 051/111] MIPS: OCTEON: fix kexec support

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Aurelien Jarno <aurelien@...el32.net>

commit 8a644c64a9f1aefb99fdc4413e6b7fee17809e38 upstream.

Commit 62cac480f33f ("MIPS: kexec: Make a framework for both jumping and
halting on nonboot CPUs") broke the build of the OCTEON platform as
the relocated_kexec_smp_wait() is now static and not longer exported in
kexec.h.

Replace it by kexec_reboot() like it has been done in other places.
