Hi Xiantao,
I general I think the code in this patch is fine. I have a couple of
nit-picking comments:
> + if (target_mask&0x1) {
The formatting here isn't quite what most of the kernel does. It would
be better if you added spaces so it's a little easier to read, ie:
if (target_mask & 0x1) {
> + p = &__per_cpu_idtrs[cpu][0][0];
> + for (i = IA64_TR_ALLOC_BASE; i <= per_cpu(ia64_tr_used,
> cpu);
> + i++,
> p++) {
> + if (p->pte&0x1)
Same thing here.
> +#define RR_TO_RID(rr) ((rr)<<32>>40)
I would prefer to have this one defined like this:
#define RR_TO_RID(rr) (rr >> 8) & 0xffffff
It should generate the same code, but is more intuitive for the reader.
Otherwise I think this patch is fine - this is really just cosmetics.
Cheers,
Jes
