Linus Torvalds ff2ae607c6 SPDX patches for 5.7-rc1.
Here are 3 SPDX patches for 5.7-rc1.
 
 One fixes up the SPDX tag for a single driver, while the other two go
 through the tree and add SPDX tags for all of the .gitignore files as
 needed.
 
 Nothing too complex, but you will get a merge conflict with your current
 tree, that should be trivial to handle (one file modified by two things,
 one file deleted.)
 
 All 3 of these have been in linux-next for a while, with no reported
 issues other than the merge conflict.

Steven Rostedt (VMware) 401d61cbd4 tools lib traceevent: Remove extra '\n' in print_event_time()
If the precision of print_event_time() is zero or greater than the
timestamp, it uses a different format. But that format had an extra new
line at the end, and caused the output to not look right:

Sudip Mukherjee c09982f8e2 libtraceevent: Allow custom libdir path
When I use prefix=/usr and try to install libtraceevent in my laptop it
tries to install in /usr/lib64. I am not having any folder as /usr/lib64
and also the debian policy doesnot allow installing in /usr/lib64. It
should be in /usr/lib/x86_64-linux-gnu/.

Quote: No package for a 64 bit architecture may install files in
	/usr/lib64/ or in a subdirectory of it.

ref: https://www.debian.org/doc/debian-policy/ch-opersys.html

Make it more flexible by allowing to mention libdir_relative while
installing so that distros can mention the path according to their
policy or use the default one.

Sudip Mukherjee 587db8ebda libtraceevent: Fix lib installation with O=
When we use 'O=' with make to build libtraceevent in a separate folder
it fails to install libtraceevent.a and libtraceevent.so.1.1.0 with the
error:

  INSTALL  /home/sudip/linux/obj-trace/libtraceevent.a
  INSTALL  /home/sudip/linux/obj-trace/libtraceevent.so.1.1.0

  cp: cannot stat 'libtraceevent.a': No such file or directory
  Makefile:225: recipe for target 'install_lib' failed
  make: *** [install_lib] Error 1

I used the command:

  make O=../../../obj-trace DESTDIR=~/test prefix==/usr  install

It turns out libtraceevent Makefile, even though it builds in a separate
folder, searches for libtraceevent.a and libtraceevent.so.1.1.0 in its
source folder.

So, add the 'OUTPUT' prefix to the source path so that 'make' looks for
the files in the correct place.

Sudip Mukherjee 68401a1799 libtraceevent: Fix header installation
When we passed some location in DESTDIR, install_headers called
do_install with DESTDIR as part of the second argument.

But do_install is again using '$(DESTDIR_SQ)$2', so as a result the
headers were installed in a location $DESTDIR/$DESTDIR.

In my testing I passed DESTDIR=/home/sudip/test and the headers were
installed in: /home/sudip/test/home/sudip/test/usr/include/traceevent.

Lets remove DESTDIR from the second argument of do_install so that the
headers are installed in the correct location.

Tzvetomir Stoyanov 38847db974 libtraceevent, perf tools: Changes in tep_print_event_* APIs
Libtraceevent APIs for printing various trace events information are
complicated, there are complex extra parameters. To control the way
event information is printed, the user should call a set of functions in
a specific sequence.

These APIs are reimplemented to provide a more simple interface for
printing event information.

Removed APIs:

 	tep_print_event_task()
	tep_print_event_time()
	tep_print_event_data()
	tep_event_info()
	tep_is_latency_format()
	tep_set_latency_format()
	tep_data_latency_format()
	tep_set_print_raw()

A new API for printing event information is introduced:
   void tep_print_event(struct tep_handle *tep, struct trace_seq *s,
		        struct tep_record *record, const char *fmt, ...);
where "fmt" is a printf-like format string, followed by the event
fields to be printed. Supported fields:
 TEP_PRINT_PID, "%d" - event PID
 TEP_PRINT_CPU, "%d" - event CPU
 TEP_PRINT_COMM, "%s" - event command string
 TEP_PRINT_NAME, "%s" - event name
 TEP_PRINT_LATENCY, "%s" - event latency
 TEP_PRINT_TIME, %d - event time stamp. A divisor and precision
   can be specified as part of this format string:
   "%precision.divisord". Example:
   "%3.1000d" - divide the time by 1000 and print the first 3 digits
   before the dot. Thus, the time stamp "123456000" will be printed as
   "123.456"
 TEP_PRINT_INFO, "%s" - event information.
 TEP_PRINT_INFO_RAW, "%s" - event information, in raw format.

Example:
  tep_print_event(tep, s, record, "%16s-%-5d [%03d] %s %6.1000d %s %s",
		  TEP_PRINT_COMM, TEP_PRINT_PID, TEP_PRINT_CPU,
		  TEP_PRINT_LATENCY, TEP_PRINT_TIME, TEP_PRINT_NAME, TEP_PRINT_INFO);
Output:
	ls-11314 [005] d.h. 185207.366383 function __wake_up

took an extremely long time. I profiled it down to add_new_comm(), which
was doing a qsort() call on an array that was pretty much already sorted
(all but the last element. qsort() isn't very efficient when dealing
with mostly sorted arrays, and this definitely showed its issues.

When adding a new task to the task list, instead of using qsort(), do
another bsearch() with a function that will find the element before
where the new task will be inserted in. Then simply shift the rest of
the array, and insert the task where it belongs.

Steven Rostedt (VMware) b0215e2d6a tools lib traceevent: Do not free tep->cmdlines in add_new_comm() on failure
If the re-allocation of tep->cmdlines succeeds, then the previous
allocation of tep->cmdlines will be freed. If we later fail in
add_new_comm(), we must not free cmdlines, and also should assign
tep->cmdlines to the new allocation. Otherwise when freeing tep, the
tep->cmdlines will be pointing to garbage.

Steven Rostedt (VMware) 82a2f88458 tools lib traceevent: Fix "robust" test of do_generate_dynamic_list_file
The tools/lib/traceevent/Makefile had a test added to it to detect a failure
of the "nm" when making the dynamic list file (whatever that is). The
problem is that the test sorts the values "U W w" and some versions of sort
will place "w" ahead of "W" (even though it has a higher ASCII value, and
break the test.

Add 'tr "w" "W"' to merge the two and not worry about the ordering.
