I have made this CONFIG_SPARC_LEON because I'm not sure if other SMP
SPARC32 supports the pmc idle. One can see from row 109 above that in
single-processor pmc_idle() is called in the same mannor, however no for
SMP... perhaps it is a meaning with that? I don't want to break
anything, if you think is shuold not be ifdeffed I will remove it and
repost.
