The patch ec5ce098: "tracing: Allow whitespace to surround hist trigger filter" from Jan 15, 2018, leads to the following Smatch static checker warning: kernel/trace/trace_events_hist.c:6199 event_hist_trigger_parse() warn: 'p' can't be NULL. Since p is always checked for a NULL value at the top of loop and nothing in the rest of the loop will set it to NULL, the warning is correct and might as well be 1 to silence the warning.

The recent rename of event_hist_trigger_parse() caused smatch re-evaluation of trace_events_hist.c and as a result an old warning was found: kernel/trace/trace_events_hist.c:6174 event_hist_trigger_parse() error: we previously assumed 'glob' could be null (see line 6166) glob should never be null (and apparently smatch can also figure that out and skip the warning when using the cross-function DB (but which can't be used with a 0day build as it takes too much time to generate)). Nonetheless for clarity, remove the test but add a WARN_ON() in case the code ever changes.

First S390 complained that the sorting of the mcount sections at build time caused the kernel to crash on their architecture. Now PowerPC is complaining about it too. And also ARM64 appears to be having issues. It may be necessary to also update the relocation table for the values in the mcount table. Not only do we have to sort the table, but also update the relocations that may be applied to the items in the table. If the system is not relocatable, then it is fine to sort, but if it is, some architectures may have issues (although x86 does not as it shifts all addresses the same). Add a HAVE_BUILDTIME_MCOUNT_SORT that an architecture can set to say it is safe to do the sorting at build time. Also update the config to compile in build time sorting in the sorttable code in scripts/ to depend on CONFIG_BUILDTIME_MCOUNT_SORT.

Pull ftrace fix from Steven Rostedt: "Fix s390 breakage from sorting mcount tables. The latest merge of the tracing tree sorts the mcount table at build time. But s390 appears to do things differently (like always) and replaces the sorted table back to the original unsorted one. As the ftrace algorithm depends on it being sorted, bad things happen when it is not, and s390 experienced those bad things. Add a new config to tell the boot if the mcount table is sorted or not, and allow s390 to opt out of it" * tag 'trace-v5.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Fix assuming build time sort works for s390

To speed up the boot process, as mcount_loc needs to be sorted for ftrace to work properly, sorting it at build time is more efficient than boot up and can save milliseconds of time. Unfortunately, this change broke s390 as it will modify the mcount_loc location after the sorting takes place and will put back the unsorted locations. Since the sorting is skipped at boot up if it is believed that it was sorted at run time, ftrace can crash as its algorithms are dependent on the list being sorted. Add a new config BUILDTIME_MCOUNT_SORT that is set when BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine if sorting should take place at boot up.

A previous patch preventing "attr->sample_period" values from being overridden in pfm events changed a related behaviour in arm-spe. Before said patch: perf record -c 10000 -e arm_spe_0// -- sleep 1 Would yield an SPE event with period=10000. After the patch, the period in "-c 10000" was being ignored because the arm-spe code initializes sample_period to a non-zero value. This patch restores the previous behaviour for non-libpfm4 events.
