    Subject[RFC PATCH 0/2 v2] Unified trace buffer (take two)

    Again: this is a proof of concept, just spitting out code for comments.

    Here's my second attempt.

    Changes since version 1:

    - Ripped away all the debugfs and event registration from ring buffers.

    - Removed the mergesort from the ringbuffer and pushed that up to the

    - Changed the event header to what Linus suggested (we can discuss this
    and try other suggestions for v3, namely Peter Zijlstras ideas).

    struct {
    u32 time_delta:27, type:5;
    u32 data;
    u64 array[];

    - Added timestamp at beginning of each page and implemented a way
    for all events to get the full timestamp from the previous.

    - The changes to ftrace on this release was much less than the first
