ARM: OMAP2+: first hwmod fix for v4.6-rc

Fix a longstanding bug in the hwmod code that could cause
hardware SYSCONFIG register values to not match the kernel's
idea of what they should be, and that could result in lower
performance during IP block idle entry.

Basic build, boot, and PM test logs are available here:

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
"Main kernel side changes:

- Big reorganization of the x86 perf support code. The old code grew
organically deep inside arch/x86/kernel/cpu/perf* and its naming
became somewhat messy.

The new location is under arch/x86/events/, using the following
cleaner hierarchy of source code files:

perf/x86: Move perf_event.c .................. => x86/events/core.c
perf/x86: Move perf_event_amd.c .............. => x86/events/amd/core.c

perf/x86: Move perf_event_intel_bts.c ........ => x86/events/intel/bts.c
perf/x86: Move perf_event_intel.c ............ => x86/events/intel/core.c
perf/x86: Move perf_event_intel_cqm.c ........ => x86/events/intel/cqm.c

perf/x86: Move perf_event_msr.c .............. => x86/events/msr.c

(Borislav Petkov)

- Update various x86 PMU constraint and hw support details (Stephane
Eranian)

- Optimize kprobes for BPF execution (Martin KaFai Lau)

- Rewrite, refactor and fix the Intel uncore PMU driver code (Thomas
Gleixner)

- Rewrite, refactor and fix the Intel RAPL PMU code (Thomas Gleixner)

- Various fixes and smaller cleanups.

There are lots of perf tooling updates as well. A few highlights:

perf report/top:

- Hierarchy histogram mode for 'perf top' and 'perf report',
showing multiple levels, one per --sort entry: (Namhyung Kim)

On a mostly idle system:

# perf top --hierarchy -s comm,dso

Then expand some levels and use 'P' to take a snapshot:

# cat perf.hist.0
- 92.32% perf
58.20% perf
22.29% libc-2.22.so
5.97% [kernel]
4.18% libelf-0.165.so
1.69% [unknown]
- 4.71% qemu-system-x86
3.10% [kernel]
1.60% qemu-system-x86_64 (deleted)
+ 2.97% swapper
#

- Add 'L' hotkey to dynamicly set the percent threshold for
histogram entries and callchains, i.e. dynamicly do what the
--percent-limit command line option to 'top' and 'report' does.
(Namhyung Kim)

perf mem:

- Allow specifying events via -e in 'perf mem record', also listing
what events can be specified via 'perf mem record -e list' (Jiri
Olsa)

perf record:

- Add 'perf record' --all-user/--all-kernel options, so that one
can tell that all the events in the command line should be
restricted to the user or kernel levels (Jiri Olsa), i.e.:

perf record -e cycles:u,instructions:u

is equivalent to:

perf record --all-user -e cycles,instructions

- Make 'perf record' collect CPU cache info in the perf.data file header:

$ perf record usleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.017 MB perf.data (7 samples) ]
$ perf report --header-only -I | tail -10 | head -8
# CPU cache info:
# L1 Data 32K [0-1]
# L1 Instruction 32K [0-1]
# L1 Data 32K [2-3]
# L1 Instruction 32K [2-3]
# L2 Unified 256K [0-1]
# L2 Unified 256K [2-3]
# L3 Unified 4096K [0-3]

Will be used in 'perf c2c' and eventually in 'perf diff' to
allow, for instance running the same workload in multiple
machines and then when using 'diff' show the hardware difference.
(Jiri Olsa)

- Improved support for Java, using the JVMTI agent library to do
jitdumps that then will be inserted in synthesized
PERF_RECORD_MMAP2 events via 'perf inject' pointed to synthesized
ELF files stored in ~/.debug and keyed with build-ids, to allow
symbol resolution and even annotation with source line info, see
the changeset comments to see how to use it (Stephane Eranian)

perf script/trace:

- Decode data_src values (e.g. perf.data files generated by 'perf
mem record') in 'perf script': (Jiri Olsa)

# perf script
perf 693 [1] 4.088652: 1 cpu/mem-loads,ldlat=30/P: ffff88007d0b0f40 68100142 L1 hit|SNP None|TLB L1 or L2 hit|LCK No <SNIP>
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- Improve support to 'data_src', 'weight' and 'addr' fields in
'perf script' (Jiri Olsa)

- Handle empty print fmts in 'perf script -s' i.e. when running
python or perl scripts (Taeung Song)

perf stat:

- 'perf stat' now shows shadow metrics (insn per cycle, etc) in
interval mode too. E.g:

# perf stat -I 1000 -e instructions,cycles sleep 1
# time counts unit events
1.000215928 519,620 instructions # 0.69 insn per cycle
1.000215928 752,003 cycles
<SNIP>

- Port 'perf kvm stat' to PowerPC (Hemant Kumar)

- Implement CSV metrics output in 'perf stat' (Andi Kleen)

perf BPF support:

- Support converting data from bpf events in 'perf data' (Wang Nan)

- Print bpf-output events in 'perf script': (Wang Nan).

# perf record -e bpf-output/no-inherit,name=evt/ -e ./test_bpf_output_3.c/map:channel.event=evt/ usleep 1000
# perf script
usleep 4882 21384.532523: evt: ffffffff810e97d1 sys_nanosleep ([kernel.kallsyms])
BPF output: 0000: 52 61 69 73 65 20 61 20 Raise a
0008: 42 50 46 20 65 76 65 6e BPF even
0010: 74 21 00 00 t!..
BPF string: "Raise a BPF event!"
#

- Add API to set values of map entries in a BPF object, be it
individual map slots or ranges (Wang Nan)

- Introduce support for the 'bpf-output' event (Wang Nan)

- Add glue to read perf events in a BPF program (Wang Nan)

- Improve support for bpf-output events in 'perf trace' (Wang Nan)

for details!"
