ARM: 9160/1: NOMMU: Reload __secondary_data after PROCINFO_INITFUNC
__secondary_data used to reside in r7 around call to PROCINFO_INITFUNC. After commit 95731b8ee63e ("ARM: 9059/1: cache-v7: get rid of mini-stack") r7 is used as a scratch register, so we have to reload __secondary_data before we setup the stack pointer. Fixes: 95731b8ee63e ("ARM: 9059/1: cache-v7: get rid of mini-stack") Signed-off-by: Vladimir Murzin <vladimir.murzin@arm.com> Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk>
