From 7202216a6f34d571a22274e729f841256bf8b1ef Mon Sep 17 00:00:00 2001 From: Vladimir Murzin Date: Thu, 25 Nov 2021 12:05:19 +0100 Subject: 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.
