 Introduces the LTT serialization library. Cuts the kernel patch size from 2M to 500k. Deprecates genevent for kernel instrumentation, but keeps backward compatibility with genevent generated code (still used for user space tracing). Slightly longer execution time at instrumentation site (270ns vs 200ns for 4 bytes write on P4 3GHz), but the global advantage of using less memory, and therefore less cache, should overweight this cost in cycles. Note : In this version, the ltt-probe-* kernel modules and the XML definitions must be kept in sync by hand, otherwise, LTTV will detect a size mismatch between the kernel trace and the expected event size..

 LTTng 0.38 and LTTV 0.11.0

I just cleaned up the LTTng trace format heavily, got rid of the heartbeat timer (by checking for overflow at the tracing site), got rid of the "special" compact channel; it removed about 5 FIXMEs in LTTng (cpu hotplug and compact channel related). Everything is compact now :

This is much more compact than the previous format, and permits a "tracer debug mode" in menuconfig which enables the "event size" field, which helps cross-checking the size expected by the userspace tool and the size written by the kernel.

Note that this "event size" field can eventually be enabled on a per-event or per-channel basis. This will probably be useful to encode "binary blobs"...

I also cleanup up the subbuffer header to make is much smaller than the previous one by removing unneeded information.

I renamed the "facilities" channel to a better name : "metadata". It contains marker descriptions.

The trace major number is bumped to "2" and is completely incompatible with old LTTV.

 LTTng 0.39 and LTTV 0.11.1 fixes 32-64 bits subbuffer header portability.
LTTng 0.41 reintroduces the formal verification fix, which solves the case where the reader thinks the uncommitted subbuffer is fully committed. Unlikely to happen, but could, with small buffers especially.

LTTng 0.49 is a compile fix for userspace markers.
LTTng 0.50 fixes immediate values by reverting the "jump patching" version of immediate values. They were always on, and therefore broken. It also reimplements tracepoint, marker and imv mutexes.
LTTng 0.51 implements timestamping updates.
LTTng 0.53 implements a timer-based generic tracing clock, also includes various fixes.
LTTng 0.54 fixes the MIPS get_cycles_rate() and also change the freq_scale variable from a multiplier to a divisor.
LTTng 0.57 fixes the modification done to offset and commit count counters following formal verification so the overflow is dealt with correctly. It was causing problems on 32-bits machines after 4GB worth of data going through a buffer.

LTTng 0.165 does a large refactoring/cleanup. It relicenses all the missing LTTng files that can be shared with the UST tracer. All code imported from relay.c is now in ltt-relay-splice.c, which is kept under the GPL license (and only useful within the kernel anyway).
LTTng 0.166 fixes trace teardown error for 32-bit machines introduced in 0.165.
LTTng 0.167 supports kernel 2.6.31.6.
ltt-control 0.73 adds per-channel parameter "switch_timer" (periodic buffer flush timer interval).
