[PATCH 0/3] relay buffer-only channels (resubmit)

Hello,

This is a resubmit of the buffer-only channels implementation for
relay. Basically I followed Pekka Enberg's suggestion of doing things
CPU-hotplug-aware.

The first two patches allow relay to set up an early initcall for
registering a CPU hotplug notifier. This has to run before SMP is up,
so non-boot CPUs get a buffer as soon as they're up.

Feel free to ask any questions or suggest anything.

Eduard - Gabriel Munteanu (3):
  Unignore vmlinux.lds.h from Git.
  Better interface for hooking early initcalls.
  relay: Add buffer-only channels; useful for early logging.
