SubjectRe: [PATCH] hyper-threading information in /proc/cpuinfo

Perhaps what is really needed is a memory hierarchy in /proc (or elsewhere)
that enumerates its associated processors:

/proc/mem/
/node0..n
/main => processors: 0 1 2 3
/cache/
cache0 => processors: 0 2
cache1 => processors: 1 2

As I understand, many times ypu want to put a process in some processor
based on its sharing (or independence) of some memory level (numa local
preference, or hyperthreading)...
