2939b0469d tracing: replace TP<var> with TP_<var>
Impact: clean up

The macros TPPROTO, TPARGS, TPFMT, TPRAWFMT, and TPCMD all look a bit
ugly. This patch adds an underscore to their names.

f08340c5d6 tracepoints: Documentation TPPROTO misspelt in Documentation/tracepoints.txt
Impact: fix typo in documentation

TPPROTO is misspelt in Documentation/tracepoints.txt
Kept me wondering what was wrong, when I was trying to add a new tracepoint
subsystem.

0a7ad64531 tracepoints: format documentation
Impact: documentation update

Properly format Documentation/tracepoints.txt - it was full of
overlong lines and other typographical problems.

8fd88d1590 tracepoints: documentation fix for teardown
Impact: documentation update

Need a tracepoint_synchronize_unregister() before the end of exit()
to make sure every probe callers have exited the non preemptible
section and thus are not executing the probe code anymore.

7e066fb870 tracepoints: add DECLARE_TRACE() and DEFINE_TRACE()
Impact: API *CHANGE*. Must update all tracepoint users.

Add DEFINE_TRACE() to tracepoints to let them declare the tracepoint
structure in a single spot for all the kernel. It helps reducing memory
consumption, especially when declaring a lot of tracepoints, e.g. for
kmalloc tracing.

*API CHANGE WARNING*: now, DECLARE_TRACE() must be used in headers for
tracepoint declarations rather than DEFINE_TRACE(). This is the sane way
to do it. The name previously used was misleading.

Updates scheduler instrumentation to follow this API change.
