But it won't hurt to have it either. OK, it's more of a cleanup/nit. One question I had for the others (Andrew? other mm guys?) what is the feelings of merging this feature? Leaving aside exact implementation and just considering the high level design and cost/benefit. Last time there were some people objecting, so I wonder the situation now? So does anybody need more convincing? :) Also I will just cc linux-arch. It would be interesting to know whether powerpc, ia64, or s390 or others would be interested to use this feature?
