Subject: [PATCH 4.9 14/71] MIPS: BMIPS: Also call bmips_cpu_setup() for secondary cores

From: Florian Fainelli <f.fainelli@...il.com>

[ Upstream commit e14f633b66902615cf7faa5d032b45ab8b6fb158 ]

The initialization done by bmips_cpu_setup() typically affects both
threads of a given core, on 7435 which supports 2 cores and 2 threads,
logical CPU number 2 and 3 would not run this initialization.

Fixes: 738a3f79027b ("MIPS: BMIPS: Add early CPU initialization code")
