[PATCH] ppc64: Fix UP kernel build
CONFIG_KEXEC breaks UP builds because of a misspelled smp_release_cpus().
Also, the function isn't defined unless built with CONFIG_SMP but it is
needed if we are to go from a UP to SMP kernel. Enable it and document it.
Thanks to Steven Winiecki for reporting this and to Milton for remembering
how it's supposed to work and why.
