Commit 2dc4940360 ("regulator: tps65218: Remove all the compatibles")
changes the probe function of drivers/regulator/tps65218-regulator.c so
that it iterates through all available regulators and assumes that the
regulator IDs are sequential and match the order present in the enum
tps65218_regulator_id. However, for some reason the much older commit
c0ea88b890 ("regulator: tps65218: add support for LS3 current
regulator") updated all arrays with LS3 at the end but added it second
to last for the enum.
Because of this long standing mismatch in order between the
tps65218_regulator_id enum and the regulator_desc array in the tps65218
regulator driver, the new probe function causes the strobe values to be
associated with the wrong regulator ID. This causes LDO1 to fail to
suspend in tps65218_pmic_set_suspend_disable due to not having anything
probes for its strobe value. Fix the order in the enum so the probe
function works as the update intended.

Currently, capture is based on timeout window to configure prescaler.
PWM capture framework provides 1s window at the time of writing.
There's place for improvement, after input signal has been captured once:
- Finer tune counter clock prescaler, by using 1st capture result (with
arbitrary margin).
- Do a 2nd capture, with scaled capture window.
This increases accuracy, especially at high rates.

Add support for PMW input mode on pwm-stm32. STM32 timers support
period and duty cycle capture as long as they have at least two PWM
channels. One capture channel is used for period (rising-edge), one
for duty-cycle (falling-edge).
When there's only one channel available, only period can be captured.
Duty-cycle is simply zero'ed in such a case.
Capture requires exclusive access (e.g. no pwm output running at the
same time, to protect common prescaler).
Timer DMA burst mode (from MFD core) is being used, to take two
snapshots of capture registers (upon each period rising edge).

Pull x86 fixes from Thomas Gleixner:
"A set of fixes and updates for x86:
- Address a swiotlb regression which was caused by the recent DMA
rework and made driver fail because dma_direct_supported() returned
false
- Fix a signedness bug in the APIC ID validation which caused invalid
APIC IDs to be detected as valid thereby bloating the CPU possible
space.
- Fix inconsisten config dependcy/select magic for the MFD_CS5535
driver.
- Fix a corruption of the physical address space bits when encryption
has reduced the address space and late cpuinfo updates overwrite
the reduced bit information with the original value.
- Dominiks syscall rework which consolidates the architecture
specific syscall functions so all syscalls can be wrapped with the
same macros. This allows to switch x86/64 to struct pt_regs based
syscalls. Extend the clearing of user space controlled registers in
the entry patch to the lower registers"

Pull more perf updates from Thomas Gleixner:
"A rather large set of perf updates:
Kernel:
- Fix various initialization issues
- Prevent creating [ku]probes for not CAP_SYS_ADMIN users
Tooling:
- Show only failing syscalls with 'perf trace --failure' (Arnaldo
Carvalho de Melo)
e.g: See what 'openat' syscalls are failing:
# perf trace --failure -e openat
762.323 ( 0.007 ms): VideoCapture/4566 openat(dfd: CWD, filename: /dev/video2) = -1 ENOENT No such file or directory
<SNIP N /dev/videoN open attempts... sigh, where is that improvised camera lid?!? >
790.228 ( 0.008 ms): VideoCapture/4566 openat(dfd: CWD, filename: /dev/video63) = -1 ENOENT No such file or directory
^C#
- Show information about the event (freq, nr_samples, total
period/nr_events) in the annotate --tui and --stdio2 'perf
annotate' output, similar to the first line in the 'perf report
--tui', but just for the samples for a the annotated symbol
(Arnaldo Carvalho de Melo)
- Introduce 'perf version --build-options' to show what features were
linked, aliased as well as a shorter 'perf -vv' (Jin Yao)
- Add a "dso_size" sort order (Kim Phillips)
- Remove redundant ')' in the tracepoint output in 'perf trace'
(Changbin Du)
- Synchronize x86's cpufeatures.h, no effect on toolss (Arnaldo
Carvalho de Melo)
- Show group details on the title line in the annotate browser and
'perf annotate --stdio2' output, so that the per-event columns can
have headers (Arnaldo Carvalho de Melo)
- Fixup vertical line separating metrics from instructions and
cleaning unused lines at the bottom, both in the annotate TUI
browser (Arnaldo Carvalho de Melo)
- Remove duplicated 'samples' in lost samples warning in
'perf report' (Arnaldo Carvalho de Melo)
- Synchronize i915_drm.h, silencing the perf build process,
automagically adding support for the new DRM_I915_QUERY ioctl
(Arnaldo Carvalho de Melo)
- Make auxtrace_queues__add_buffer() allocate struct buffer, from a
patchkit already applied (Adrian Hunter)
- Fix the --stdio2/TUI annotate output to include group details, be
it for a recorded '{a,b,f}' explicit event group or when forcing
group display using 'perf report --group' for a set of events not
recorded as a group (Arnaldo Carvalho de Melo)
- Fix display artifacts in the ui browser (base class for the
annotate and main report/top TUI browser) related to the extra
title lines work (Arnaldo Carvalho de Melo)
- perf auxtrace refactorings, leftovers from a previously partially
processed patchset (Adrian Hunter)
- Fix the builtin clang build (Sandipan Das, Arnaldo Carvalho de
Melo)
- Synchronize i915_drm.h, silencing a perf build warning and in the
process automagically adding support for a new ioctl command
(Arnaldo Carvalho de Melo)
- Fix a strncpy issue in uprobe tracing"

x86/mm: Fix bogus warning during EFI bootup, use boot_cpu_has() instead of this_cpu_has() in build_cr3_noflush()
Pull irq affinity fixes from Thomas Gleixner:
- Fix error path handling in the affinity spreading code
- Make affinity spreading smarter to avoid issues on systems which
claim to have hotpluggable CPUs while in fact they can't hotplug
anything.
So instead of trying to spread the vectors (and thereby the
associated device queues) to all possibe CPUs, spread them on all
present CPUs first. If there are left over vectors after that first
step they are spread among the possible, but not present CPUs which
keeps the code backwards compatible for virtual decives and NVME
which allocate a queue per possible CPU, but makes the spreading
smarter for devices which have less queues than possible or present
CPUs.
* 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
genirq/affinity: Spread irq vectors among present CPUs as far as possible
genirq/affinity: Allow irq spreading from a given starting point
genirq/affinity: Move actual irq vector spreading into a helper function
genirq/affinity: Rename *node_to_possible_cpumask as *node_to_cpumask
genirq/affinity: Don't return with empty affinity masks on error
