The scsi and cfg80211 plugins cast between unsigned long long and
pointers, which is problematic for architectures where unsigned long
long is wider than the native pointer size:
linux/tools/lib/traceevent/plugin_scsi.c: In function ‘process_scsi_trace_parse_cdb’:
linux/tools/lib/traceevent/plugin_scsi.c:408:26: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
scsi_trace_parse_cdb(s, (unsigned char *) args[1], args[2]);
linux/tools/lib/traceevent/plugin_cfg80211.c: In function ‘process___le16_to_cpup’:
linux/tools/lib/traceevent/plugin_cfg80211.c:11:18: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
uint16_t *val = (uint16_t *) args[0];
This patch adds an intermediate cast to unsigned long, silencing the
warning.

which triggers when traceevent library needs to be rebuilt, but we have

both Makefile parts (for detached output directory (O=...) the

Move debugfs.* to api/fs/. We have a common tools/lib/api/ place where
the Makefile lives and then we place the headers in subdirs.
For example, all the fs-related stuff goes to tools/lib/api/fs/ from
which we get libapikfs.a (acme got almost the naming he wanted :-)) and
we link it into the tools which need it - in this case perf and
tools/vm/page-types.
acme:
"Looking at the implementation, I think some tools can even link
directly to the .o files, avoiding the .a file altogether.
But that is just an optimization/finer granularity tools/lib/
cherrypicking that toolers can make use of."

When Jiri Olsa was writing a function callback for
scsi_trace_parse_cdb(), he thought that the traceevent library had a
bug in it because he was getting this error:
Error: expected ')' but read ','
Error: expected ')' but read ','
Error: expected ')' but read ','
Error: expected ')' but read ','
But in truth, he didn't have the write number of arguments for the
function callback, and the error was the library detecting the
discrepancy. A better error message would have prevented the confusion:
Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_timeout has more
Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_start has more
Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_error has more
Error: function 'scsi_trace_parse_cdb()' only expects 2 arguments but event scsi_dispatch_cmd_done has more
Or
Error: function 'scsi_trace_parse_cdb()' expects 4 arguments but event scsi_dispatch_cmd_timeout only uses 3
Error: function 'scsi_trace_parse_cdb()' expects 4 arguments but event scsi_dispatch_cmd_start only uses 3

Several cleanups suggested by Namhyung:
* Remove index field from struct func_stack as it's not needed.
* Rename get_index into add_and_get_index.
* Use '%*X' format string capability instead of the loop

The pevent_print_func_field function encompasses all the functionality
used in the hrtimer_start handler. Change the handler to use this
function.
This also unifies the function field output with the
hrtimer_expire_entry handler.

There's no need for following functions to be global:
process_jbd2_dev_to_name
process_jiffies_to_msecs
Make them static.

Backporting mac80211 plugin.
Backported from Steven Rostedt's trace-cmd repo (HEAD 0f2c2fb):
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
This plugin adds changed field resolving for
mac80211:drv_bss_info_changed tracepoint event.
The diff of 'perf script' output generated by old and new code:
(data was generated by 'perf record -e 'mac80211:drv_bss_info_changed' -a')
--- script.mac80211.old
+++ script.mac80211.new
- ifconfig 3711 [000] 1290.446492: mac80211:drv_bss_info_changed: phy0 vif:wlan0(2) changed:0x309f
+ ifconfig 3711 [000] 1290.446492: mac80211:drv_bss_info_changed: phy0 vif:wlan0(2)
+ assoc:0 aid:2 cts:0 shortpre:0 shortslot:0 dtimper:1
+ bcnint:102 assoc_cap:0x431 basic_rates:0xf enable_beacon:0
+ ht_operation_mode:0
Omitting the mac80211:drv_config tracepoint handling because the kernel
tracepoint changed its prototype and the plugin handler is no longer
working.
