[Cbe-oss-dev] [PATCH] ps3: fix CONFIG_SMP=n, CONFIG_KEXEC=y build

[Jeremy Kerr]

Currently, the ps3 kernel fails to build without smp but with kexec, as
ps3_kexec_cpu_down needs ps3_smp_cleanup_cpu, which isn't defined on UP
kernels. This change adds an empty ps3_smp_cleanup_cpu for UP kernels.

Booted on ps3.
