commit 379c590113ce46f605439d4887996c60ab8820cc upstream.
When the addresses of the shmobile_smp_mpidr, shmobile_smp_fn, and shmobile_smp_arg variables are not multiples of 4 bytes, secondary CPU bring-up fails:
smp: Bringing up secondary CPUs ... CPU1: failed to come online CPU2: failed to come online CPU3: failed to come online smp: Brought up 1 node, 1 CPU
Fix this by adding the missing alignment directive.
