e767b3530a ARM: SoC drivers for v5.12
Updates for SoC specific drivers include a few subsystems that
 have their own maintainers but send them through the soc tree:
 
 SCMI firmware:
  - add support for a completion interrupt
 
 Reset controllers:
  - new driver for BCM4908
  - new devm_reset_control_get_optional_exclusive_released()
    function
 
 Memory controllers:
  - Renesas RZ/G2 support
  - Tegra124 interconnect support
  - Allow more drivers to be loadable modules
 
 TEE/optee firmware:
  - minor code cleanup
 
 The other half of this is SoC specific drivers that do not
 belong into any other subsystem, most of them living in
 drivers/soc:
 
  - Allwinner/sunxi power management work
  - Allwinner H616 support
 
  - ASpeed AST2600 system identification support
 
  - AT91 SAMA7G5 SoC ID driver
  - AT91 SoC driver cleanups
 
  - Broadcom BCM4908 power management bus support
 
  - Marvell mbus cleanups
 
  - Mediatek MT8167 power domain support
 
  - Qualcomm socinfo driver support for PMIC
  - Qualcomm SoC identification for many more products
 
  - TI Keystone driver cleanups for PRUSS and elsewhere

82851fce61 ARM: SoC devicetree updates for v5.12
After the last release contained a surprising amount of new 32-bit
 machines, this time two thirds of the code changes are for 64-bit.
 
 The usual updates to existing files include:
 
  - Device tree compiler warning fixes for Berlin, Renesas, SoCFPGA,
    nomadik, stm32, Allwinner, TI Keystone
 
  - Support for additional devices on existing machines on Renesas, SoCFPGA,
    at91, hisilicon, OMAP, Tegra, TI K3, Allwinner, Broadcom, ux500,
    Mediatek, Marvell Armada, Marvell MMP, ZynqMP, AMLogic, Qualcomm,
    i.MX, Layerscape, Actions, ASpeed, Toshiba
 
  - Cleanups and minor fixes for Renesas, at91, mstar, ux500, Samsung,
    stm32, Tegra, Broadcom, Mediatek, Marvell MMP, AMLogic, Qualcomm,
    i.MX, Rockchip, ASpeed, Zynq
 
 Only three new SoCs this time, but a number of boards across:
 
 Renesas:
  - Two Beacon EmbeddedWorks boards (RZ/G2H and RZ/G2N based)

584ce3c9b4 SoC platform removal
There are a lot of platforms that have not seen any interesting code
 changes in the past five years or more.
 
 I made a list and asked around which ones are no longer in use [1], and
 received confirmation about six ARM platforms and the TI C6x architecture
 that have all reached the end of their life upstream, with no known
 users remaining:
 
  - efm32 -- added in 2011, first Cortex-M, no notable changes after 2013
  - picoxcell -- added in 2011, abandoned after 2012 acquisition
  - prima2 -- added in 20111, no notable changes since 2015
  - tango -- added in 2015, sporadic changes until 2017, but abandoned
  - u300 -- added in 2009, no notable changes since 2013
  - zx --added in 2015 for both 32, 2017 for 64 bit, no notable changes
  - arch/c6x -- added in 2011, but work stalled soon after that
 
 A number of other platforms on the original list turned out to still
 have users. In some cases there are out-of-tree patches and users
 that plan to contribute them in the future, in other cases the code
 is complete and works reliably.

 - A build fix for the Atmel SAM9 platform to allow building

 - A DT fix for ethernet on Intel SoCFPGA, this has been broken
   since it was added in v5.4.

eacd9aa8ce fix handling of nd->depth on LOOKUP_CACHED failures in try_to_unlazy*
After switching to non-RCU mode, we want nd->depth to match the number
of entries in nd->stack[] that need eventual path_put().
legitimize_links() takes care of that on failures; unfortunately,
failure exits added for LOOKUP_CACHED do not.

We could add the logics for that into those failure exits, both in
try_to_unlazy() and in try_to_unlazy_next(), but since both checks
are immediately followed by legitimize_links() and there's no calls
of legitimize_links() other than those two...  It's easier to
move the check (and required handling of nd->depth on failure) into
legitimize_links() itself.

[caught by Jens: ... and since we are zeroing ->depth here, we need
to do drop_links() first]

c85c9a2c6e kprobes: Fix to delay the kprobes jump optimization
Commit 36dadef23f ("kprobes: Init kprobes in early_initcall")
moved the kprobe setup in early_initcall(), which includes kprobe
jump optimization.
The kprobes jump optimizer involves synchronize_rcu_tasks() which
depends on the ksoftirqd and rcu_spawn_tasks_*(). However, since
those are setup in core_initcall(), kprobes jump optimizer can not
run at the early_initcall().

To avoid this issue, make the kprobe optimization disabled in the
early_initcall() and enables it in subsys_initcall().

Note that non-optimized kprobes is still available after
early_initcall(). Only jump optimization is delayed.

41401ac677 drm/amd/display: Add FPU wrappers to dcn21_validate_bandwidth()
dcn21_validate_bandwidth() calls functions that use floating point math.
On my machine this sometimes results in simd exceptions when there are
other FPU users such as KVM virtual machines running. The screen freezes
completely in this case.

Wrapping the function with DC_FP_START()/DC_FP_END() seems to solve the
problem. This mirrors the approach used for dcn20_validate_bandwidth.

11d45d4fb9 perf test: Output the sub testing result in cs-etm
The CoreSight testing contains sub cases, e.g. every CPU iterates the
possible conntected sinks and tests the paths between the associated ETM
with the found sink.  Besides the per-thread testing, it also contains
system wide testing and snapshot testing.

To easier observe results for the sub cases, this patch introduces a new
function arm_cs_report(), it outputs the result as "PASS" or "FAIL" for
every sub case; and it records the error in the variable "glb_err" which
is used as the final return value when exits the testing.

Before:

iterates between ETMs and sinks.

For a neat output format, this patch redirects the output logs to
"/dev/null", thus can avoid to flood logs.  And it removes the redundant
log for CPU number and device name, which have already printed out the
relevant info in the function record_touch_file().

80a038860b perf intel-pt: Amend decoder to track the NR flag
The PIP packet NR (non-root) flag indicates whether or not a virtual
machine is being traced (NR=1 => VM). Add support for tracking its value.

In particular note that the PIP packet (outside of PSB+) will be
associated with a TIP packet from which address the NR value takes
effect. At that point, there is a branch from_ip, to_ip with
corresponding from_nr and to_nr.

In the event of VM-Entry failure, there should still PIP and TIP packets
that can be followed in the same way.

Also note that this assumes that a host VMM is not employing VMX controls
that affect Intel PT, e.g. to hide the host from a guest using Intel PT.

d58b3f7e70 perf auxtrace: Automatically group aux-output events
aux-output events need to have an AUX area event as the group leader.
However, grouping events does not allow the AUX area event to be given
an address filter because the --filter option must come after the event,
which conflicts with the grouping syntax.

To allow filtering in that case, automatically create a group since that
is the requirement anyway.

Example: (requires Intel Tremont)

  perf record -c 500 -e 'intel_pt//u' --filter 'filter main @ /bin/ls' -e 'cycles/aux-output/pp' ls

fbefe9c2f8 perf tools: Support arch specific PERF_SAMPLE_WEIGHT_STRUCT processing
For X86, the var2_w field of PERF_SAMPLE_WEIGHT_STRUCT stands for the
instruction latency. Current perf forces the var2_w to the data->ins_lat
in the generic code. It works well for now because X86 is the only
architecture that supports the PERF_SAMPLE_WEIGHT_STRUCT, but it may
bring problems once other architectures support the sample type.  For
example, the var2_w may be used to capture something else on PowerPC.

Create two architecture specific functions to parse and synthesize the
weight related samples. Move the X86 specific codes to the X86 version
functions. Other architectures can implement their own functions later
separately.

c840cbfeff perf intel-pt: Add PSB events
Emitting a PSB+ can cause a CPU a slight delay. When doing timing analysis
of code with Intel PT, it is useful to know if a timing bubble was caused
by Intel PT or not. Add reporting of PSB events via perf script. PSB
events are printed with the existing itrace 'p' option which also prints
power and frequency changes. The PSB event contains the trace offset at
which the PSB occurs, to allow easy reference back to the PSB+ packets.

The PSB event timestamp is always the timestamp from the PSB+ TSC
packet, and the ip is always the address from the PSB+ FUP packet.

The code changes are non-trivial because the decoder must walk to the
PSB+ FUP address before outputting the PSB event.

Example:

  $ perf record -e intel_pt/cyc,psb_period=0/u uname

  [ perf record: Captured and wrote 0.046 MB perf.data ]

6af4b60033 perf intel-pt: Fix IPC with CYC threshold
The code assumed every CYC-eligible packet has a CYC packet, which is not
the case when CYC thresholds are used. Fix by checking if a CYC packet is
actually present in that case.

20aa39708a perf intel-pt: Fix premature IPC
The code assumed a change in cycle count means accurate IPC. That is not
correct, for example when sampling both branches and instructions, or at
a FUP packet (which is not CYC-eligible) address. Fix by using an explicit
flag to indicate when IPC can be sampled.
