Re: [Lse-tech] NUMA sched -> pooling scheduler (inc HT)

Mmm... seems I may have got the ordering of the cpus wrong.
Something like this might work better in sched_topo_ht.h
(yeah, it's ugly. I don't care).

static inline int pool_to_cpu_mask (int pool)
{
return ( (1UL << pool) || (1UL << cpu_sibling_map[pool]));
}

static inline cpu_to_pool (int cpu)
{
return min(cpu, cpu_sibling_map[cpu]);
}

Thanks to Andi, Zwane, and Bill for the corrective baseball bat strike.
I changed the macros to inlines to avoid the risk of double eval.
