This is a behavior change -- the thread_siblings attribute now reflects only online siblings, whereas it would display offline siblings before. The new behavior matches that of x86, and is arguably more useful. Signed-off-by: Nathan Lynch Signed-off-by: Benjamin Herrenschmidt --- Reading git-diff-tree failed
