The introduction of the new 'DECLARE_EVENT_CLASS()' obviates the
need for the 'TRACE_EVENT()' macro in some cases. Thus, docbook
style comments that used to live with 'TRACE_EVENT()' are now
moved to 'DEFINE_EVENT()'. Thus, we need to make the docbook
system understand the new 'DEFINE_EVENT()' macro. In addition
I've tried to futureproof the patch, by also adding support for
'DEFINE_SINGLE_EVENT()', since there has been discussion about
renaming: TRACE_EVENT() -> DEFINE_SINGLE_EVENT().Without this patch the tracepoint docbook fails to build.
I've verified that this patch correctly builds the tracepoint
docbook which currently covers signals, and irqs.Changes in v2:

If a permission name is long enough the selinux class definition generation
tool will go into a infinite loop. This is because it's macro max() is
fooled into thinking it is dealing with unsigned numbers. This patch makes
sure the macro always uses signed number so 1 > -1.Signed-off-by: Eric Paris

If the user has an older version of objcopy, that can not handle
converting local symbols to global and vice versa, then some
functions will not be part of the dynamic function tracer. The current
code in recordmcount.pl will print a warning in this case. Unfortunately,
there exists lots of files that may have this issue with older objcopys
and this will cause a warning for every file compiled with this
issue.This patch solves this overwhelming output by creating a
.tmp_quiet_recordmcount file on the first instance the warning is
encountered. The warning will not print if this file exists.The temp file is deleted at the beginning of the compile to ensure that
the warning will happen once again on new compiles (because the issue
is still present).Reported-by: Andrew Morton

If a weak function is used as a relocation reference for mcount callers
and that function is overridden, it will cause ftrace to fail at run time.The current code should prevent a weak function from being used, but if
one is, the code should exit with an error to fail at compile time.Signed-off-by: Li Hong

The current logic to check objcopy's version is incorrect. This patch

The ftrace.c file may reference the mcount function and this may interfere
with the recordmcount.pl processing. To avoid this, the code does not
process the kernel/trace/ftrace.o. But currently the check is against
a relative path. This patch modifies the check to succeed if the path
is an absolute path.Signed-off-by: Li Hong

The documentation currently says we will use the first function in a section
as a reference. The actual algorithm is: choose the first global function we
meet as a reference. If there is none, choose the first local one.
Change the documentation to be consistent with the code.Also add several other clarifications.

Ingo reported that the following lines triggered a false warning,
static struct lock_class_key rcu_lock_key;
struct lockdep_map rcu_lock_map =
STATIC_LOCKDEP_MAP_INIT("rcu_read_lock", &rcu_lock_key);
EXPORT_SYMBOL_GPL(rcu_lock_map);from kernel/rcutree.c , and the false warning looked like this,
WARNING: EXPORT_SYMBOL(foo); should immediately follow its
function/variable
+EXPORT_SYMBOL_GPL(rcu_lock_map);We actually should be checking the statement before the EXPORT_* for a
mention of the exported object, and complain where it is not there.[akpm@linux-foundation.org: coding-style fixes]

In the following code,
union thread_union init_thread_union
__attribute__((__section__(".data.init_task"))) =
{ INIT_THREAD_INFO(init_task) };There is a non-conforming declaration. It should really be like the
following,union thread_union init_thread_union
__attribute__((__section__(".data.init_task"))) = {
INIT_THREAD_INFO(init_task)
};However, checkpatch doesn't catch this right now because it doesn't
correctly evaluate the "__attribute__".It is not at all clear that we care what preceeds an assignment style
attribute when we find the open brace. Relax the test so we do not need
to check the __attribute__.Reported-by: Daniel Walker

The macro concatenation (##) sequence can cause false errors when checking
macro's. Checkpatch doesn't currently know about the operator.For example this line,
+ entry = (struct ftrace_raw_##call *)raw_data; \
is correct but it produces the following error,
ERROR: need consistent spacing around '*' (ctx:WxB)
+ entry = (struct ftrace_raw_##call *)raw_data;\
^The line above doesn't have any spacing problems, and if you remove the
macro concatenation sequence checkpatch doesn't give any errors.Extend identifier handling to include ## concatenation within the
definition of an identifier.Reported-by: Daniel Walker

zconf.y includes zconf.hash.c from the initial code section.
zconf.hash.c references the token constants from zconf.y. However,
current bison defines the token constants after the initial code
section, making zconf.hash.c fail to compile. Move the include of
zconf.hash.c later in zconf.y, so bison puts it after the token
constants.Signed-off-by: Josh Triplett
