ARM: 8739/1: NOMMU: Setup VBAR/Hivecs for secondaries cores
With switch to dynamic exception base address setting, VBAR/Hivecs set only for boot CPU, but secondaries stay unaware of that. That might lead to weird effects when trying up to bring up secondaries. Fixes: ad475117d201 ("ARM: 8649/2: nommu: remove Hivecs configuration is asm") Signed-off-by: Vladimir Murzin <vladimir.murzin@arm.com> Acked-by: afzal mohammed <afzal.mohd.ma@gmail.com> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
