Elimination of cpu_l2cache_* functions

[Marcel Moolenaar]

All,

I've been reviewing the use of the cpu_l2cache_* functions and found
that 1) they're missing from cpu_witch() and 2) they are always used
in conjunction with either cpu_idcache_* or cpu_dcache_*.

Since most CPU variants define them as null ops, isn't it better to
incorporate the functionality of cpu_l2cache_* in cpu_idcache_* and
cpu_dcache_* and eliminate them altogether?

Any objections to me removing cpu_l2cache_* and therefore changing
the semantics of cpu_idcache_* and cpu_dcahce_* to apply to all
relevant cache levels?

Thanks,
