Prev: [PATCH 00/10][RFC] tracing: Lowering the footprint of TRACE_EVENTs

Switch the TRACE_EVENT() macros to use DECLARE_TRACE_DATA(). This
patch is done to prove that the DATA macros work. If any regressions
were to surface, then this patch would help a git bisect to localize
the area.

Once again this patch increases the size of the kernel.
