590ac60d8a perf top: Display the LBR stats in callchain entry
'perf report' has supported the displaying of LBR stats (such as cycles,
predicted%) in callchain entry.

For example:

  $ perf report --branch-history --stdio

  --1.01%--intel_idle mwait.h:29
            intel_idle cpufeature.h:164 (cycles:5)
            intel_idle cpufeature.h:164 (predicted:76.4%)
            intel_idle mwait.h:102 (cycles:41)
            intel_idle current.h:15

While 'perf top' doesn't support that.

For example:

  $ perf top -a -b --call-graph branch

  -   13.86%     0.23%  [kernel]		[k] __x86_indirect_thunk_rax
     - 13.65% __x86_indirect_thunk_rax
        + 1.69% do_syscall_64
        + 1.68% do_select
        + 1.41% ktime_get
        + 0.70% __schedule
        + 0.62% do_sys_poll
          0.58% __x86_indirect_thunk_rax

Actually it's very easy to enable this feature in 'perf top'.

With this patch, the result is:

  $ perf top -a -b --call-graph branch

  $ -   13.58%     0.00%  [kernel]		[k] __x86_indirect_thunk_rax
     $ - 13.57% __x86_indirect_thunk_rax (predicted:93.9%)
        $ + 1.78% do_select (cycles:2)
        $ + 1.68% perf_pmu_disable.part.99 (cycles:1)
        $ + 1.45% ___sys_recvmsg (cycles:25)
        $ + 0.81% unix_stream_sendmsg (cycles:18)
        $ + 0.80% ktime_get (cycles:400)
          $ 0.58% pick_next_task_fair (cycles:47)
        $ + 0.56% i915_request_retire (cycles:2)
        $ + 0.52% do_sys_poll (cycles:4)

ea1fa48c05 perf stat: Handle different PMU names with common prefix
On s390 the CPU Measurement Facility for counters now supports
2 PMUs named cpum_cf (CPU Measurement Facility for counters) and
cpum_cf_diag (CPU Measurement Facility for diagnostic counters)
for one and the same CPU.

Running command

 [root@s35lp76 perf]# ./perf stat -e tx_c_tend \
	 -- ~/mytests/cf-tx-events 1

 Measuring transactions
 TX_C_TABORT_NO_SPECIAL: 0 expected:0
 TX_C_TABORT_SPECIAL: 0 expected:0
 TX_C_TEND: 1 expected:1
 TX_NC_TABORT: 11 expected:11
 TX_NC_TEND: 1 expected:1

 Performance counter stats for '/root/mytests/cf-tx-events 1':

  2      tx_c_tend

      0.002120091 seconds time elapsed

      0.000121000 seconds user
      0.002127000 seconds sys

 [root@s35lp76 perf]#

displays output which is unexpected (and wrong):

  2      tx_c_tend

The test program definitely triggers only one transaction, as shown
in line 'TX_C_TEND: 1 expected:1'.

This is caused by the following call sequence:

pmu_lookup() scans and installs a PMU.
+--> pmu_aliases() parses all aliases in directory
		.../<pmu-name>/events/* which are file names.
     +--> pmu_aliases_parse() Read each file in directory and create
                      an new alias entry. This is done with
          +--> perf_pmu__new_alias() and
	       +--> __perf_pmu__new_alias() which also check for
	                   identical alias names.

After pmu_aliases() returns, a complete list of event names
for this pmu has been created. Now function

pmu_add_cpu_aliases()   is called to add the events listed in the json
|                       files to the alias list of the cpu.
+--> perf_pmu__find_map()  Returns a pointer to the json events.

Now function pmu_add_cpu_aliases() scans through all events listed
in the JSON files for this CPU.
Each json event pmu name is compared with the current PMU being
built up and if they mismatch, the json event is added to the
current PMUs alias list.
To avoid duplicate entries the following comparison is done:

	if (!is_arm_pmu_core(name)) {
	     pname = pe->pmu ? pe->pmu : "cpu";
	     if (strncmp(pname, name, strlen(pname)))
		     continue;
     }

The culprit is the strncmp() function.

Using current s390 PMU naming, the first PMU is 'cpum_cf'
and a long list of events is added, among them 'tx_c_tend'

When the second PMU named 'cpum_cf_diag' is added, only one event
named 'CF_DIAG' is added by the pmu_aliases()  function.

Now function pmu_add_cpu_aliases() is invoked for PMU 'cpum_cf_diag'.
Since the CPUID string is the same for both PMUs, json file events
for PMU named 'cpum_cf' are added to the PMU 'cpm_cf_diag'

This happens because the strncmp() actually compares:

     strncmp("cpum_cf", "cpum_cf_diag", 6);

The first parameter is the pmu name taken from the event in
the json file. The second parameter is the pmu name of the PMU
currently being built.
They are different, but the length of the compare only tests the
common prefix and this returns 0(true) when it should return false.

Now all events for PMU cpum_cf are added to the alias list for pmu
cpum_cf_diag.

Later on in function parse_events_add_pmu() the event 'tx_c_end' is
searched in all available PMUs and found twice, adding it two
times to the evsel_list global variable which is the root
of all events. This results in a counter value of 2 instead
of 1.

Output with this patch:

 [root@s35lp76 perf]# ./perf stat -e tx_c_tend \
			-- ~/mytests/cf-tx-events 1

5d7a5bcb67 sunrpc: correct the computation for page_ptr when truncating
When truncating the encode buffer, the page_ptr is getting
advanced, causing the next page to be skipped while encoding.
The page is still included in the response, so the response
contains a page of bogus data.

We need to adjust the page_ptr backwards to ensure we encode
the next page into the correct place.

We saw this triggered when concurrent directory modifications caused
nfsd4_encode_direct_fattr() to return nfserr_noent, and the resulting
call to xdr_truncate_encode() corrupted the READDIR reply.

163c8d54a9 compiler: remove __no_sanitize_address_or_inline again
The __no_sanitize_address_or_inline and __no_kasan_or_inline defines
are almost identical. The only difference is that __no_kasan_or_inline
does not have the 'notrace' attribute.

To be able to replace __no_sanitize_address_or_inline with the older
definition, add 'notrace' to __no_kasan_or_inline and change to two
users of __no_sanitize_address_or_inline in the s390 code.

The 'notrace' option is necessary for e.g. the __load_psw_mask function
in arch/s390/include/asm/processor.h. Without the option it is possible
to trace __load_psw_mask which leads to kernel stack overflow.

437e88ab8f x86/build: Remove -pipe from KBUILD_CFLAGS
Commit 77b0bf55bc ("kbuild/Makefile: Prepare for using macros in
inline assembly code to work around asm() related GCC inlining bugs")
added -Wa,- to KBUILD_CFLAGS, which breaks compiling with Clang (hangs
indefinitely at compiling init/main.o). This happens because while Clang
accepts -pipe (and has it documented in its list of supported flags), it
silently ignores it after this 2010 commit (thanks to Nick Desaulniers
for tracking this down), meaning that gas just infinitely waits for
stdin and never receives it.

c19a12dc3d

Initially, I had suggested just add -Wa,- to KBUILD_CFLAGS when GCC was
being used but that was before realizing it is because Clang doesn't do
anything with -pipe. H. Peter Anvin suggested checking to see if -pipe
gives us any gains out of GCC. Turns out it might actually be hurting:

With -pipe:

real    3m40.813s
real    3m44.449s
real    3m39.648s

Without -pipe:

real    3m38.492s
real    3m38.335s
real    3m38.975s

The issue of -Wa,- being passed along to gas without -pipe being
supported should still probably be fixed on the LLVM side (open issue:
https://bugs.llvm.org/show_bug.cgi?id=39410) but this is not as much of
a workaround anymore since it helps both GCC and Clang.

79ef68c7e1 perf augmented_syscalls: Start collecting pathnames in the BPF program
This is the start of having the raw_syscalls:sys_enter BPF handler
collecting pointer arguments, namely pathnames, and with two syscalls
that have that pointer in different arguments, "open" as it as its first
argument, "openat" as the second.

With this in place the existing beautifiers in 'perf trace' works, those
args are shown instead of just the pointer that comes with the syscalls
tracepoints.

This also serves to show and document pitfalls in the process of using
just that place in the kernel (raw_syscalls:sys_enter) plus tables
provided by userspace to collect syscall pointer arguments.

One is the need to use a barrier, as suggested by Edward, to avoid clang
optimizations that make the kernel BPF verifier to refuse loading our
pointer contents collector.

The end result should be a generic eBPF program that works in all
architectures, with the differences amongst archs resolved by the
userspace component, 'perf trace', that should get all its tables
created automatically from the kernel components where they are defined,
via string table constructors for things not expressed in BTF/DWARF
(enums, structs, etc), and otherwise using those observability files
(BTF).

This patch adds/enables USB2.0 peripheral for R-Car [DE]3 boards.

R-Car E3 Ebisu board connects the ID pin to the SoC, so this adds
a group "usb0_id" into usb0_pins node. Also, to use SW15 pin 3 side,
this patch adds vbus0_usb2 node on r8a77990-ebisu.dts.

R-Car D3 Draak board doesn't connect the ID pin, so this adds
"renesas,no-otg-pins" property into usb2_phy0 node.

closer inspection the linked list of struct gb_loopbacks that it heads

The "official" Condor boards have always been wired to mount NFS via
GEther, not EtherAVB -- the boards resoldered for EtherAVB were local
to Cogent Embedded, so we've been having an unpleasant situation where
a "normal" Condor board still can't mount NFS (unless an EtherAVB PHY
extension board is plugged in). Switch from EtherAVB to GEther at last!

fc09ab7a76 vga_switcheroo: Fix missing gpu_bound call at audio client registration
The commit 37a3a98ef6 ("ALSA: hda - Enable runtime PM only for
discrete GPU") added a new ops gpu_bound to be called when GPU gets
bound.  The patch overlooked, however, that vga_switcheroo_enable() is
called only once at GPU is bound.  When an audio client is registered
after that point, it would miss the gpu_bound call.  This leads to the
unexpected lack of runtime PM in HD-audio side.

For addressing that regression, just call gpu_bound callback manually
at vga_switcheroo_register_audio_client() when the GPU was already
bound.
