Allow busy polling on a per-epoll context basis. The per-epoll context usec timeout value is preferred, but the pre-existing system wide sysctl value is still supported if it specified.
Why do we need u64 for usecs? I think u16 would do, and u32 would give a very solid "engineering margin". If it was discussed in previous versions I think it's worth explaining in the commit message.
