| |
Impact: New APIs
The old node_to_cpumask/node_to_pcibus returned a cpumask_t: these return a pointer to a struct cpumask. Part of removing cpumasks from the stack.
Please take (or ack) the patch for your arch so I can get substitute the callers and kill the old versions.
This does the generic ones.
