Enable regmap cache to reduce i2c transactions and corresponding
interrupts if regulator is accessed frequently. Since the register map
is small -- there's only one register in sy8824c and sy8824e, there
are only two registers in sy20276 and sy20278, so we use a FLAT regmap
cache.

In addition to the ability of merging some power outputs, this chip has
an overdrive mode.
BCORE1, BCORE2 and BPRO have this ability, in which case the legal
current draw is increased from 2 amps to 2.5 amps (at the expense of
a quiescent current increase), and the configurable current limits
are doubled.
If a current higher than maximum half-current mode is requested, enable
overdrive, and scale the current limit down.
Symmetrically, scale the current limit up when querying a overdrive-enabled
regulator.

These APIs aren't used anywhere and most-likely exist because of the
general principle of C APIs, where if an API function does an
allocation/registration, it must also have an equivalent
deallocation/deregistration counterpart.
For devm_ functions this isn't all that true (for all cases), as the idea
of these function is to provide an auto-cleanup logic on drivers/system
de-init.
Removing these discourages any weird logic that could be created with
such an API functions.

The shift setting can be calculated via the corresponding mask field,
so remove these shift fields.
The usage of da_vsel_mask is different from other mask defines because
current code does shift regval before mask with the da_vsel_mask.
Do proper shit to da_vsel_mask setting so we can calculate the shift.

This API hook isn't used anywhere outside of the regulator devres code.
This function is needed for the devm_regulator_bulk_register_supply_alias()
function on the error path, to cleanup any previously registered supply
aliases.
This change makes the devm_regulator_unregister_supply_alias() local to the
regulator core framework, to avoid it being used in any weird logic.
It's also removing the doc-string for
devm_regulator_unregister_supply_alias(), since it doesn't need to be
documented anymore, as no other external consumer should use it.

Since config.dev = pdev->dev.parent in current code, so
dev_get_drvdata(rdev->dev.parent) call in hi6421_regulator_enable
returns the drvdata of the mfd device rather than the regulator. Fix it.
This was broken while converting to use simplified DT parsing because the
config.dev changed from pdev->dev to pdev->dev.parent for parsing the
parent's of_node.

The kernel recovers in due course from missing Mlocked pages: but there
was no point in calling page_mlock() (formerly known as
try_to_munlock()) on a THP, because nothing got done even when it was
found to be mapped in another VM_LOCKED vma.
It's true that we need to be careful: Mlocked accounting of pte-mapped
THPs is too difficult (so consistently avoided); but Mlocked accounting
of only-pmd-mapped THPs is supposed to work, even when multiple mappings
are mlocked and munlocked or munmapped. Refine the tests.
There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
page_mlock_one() does not even have to worry about that complication.
(I said the kernel recovers: but would page reclaim be likely to split
THP before rediscovering that it's VM_LOCKED? I've not followed that up)
Fixes: 9a73f61bdb ("thp, mlock: do not mlock PTE-mapped file huge pages")

"New features:
- Enable use of BPF counters with 'perf stat --for-each-cgroup',

that does aggregation per-cgroup in the kernel instead of using
per-cgroup perf events.
- Add Topdown metrics L2 events as default events in 'perf stat' for
systems having those events.
Hardware tracing:
- Add a config for max loops without consuming a packet in the Intel
PT packet decoder, set via 'perf config intel-pt.max-loops=N'
Hardware enablement:
- Disable misleading NMI watchdog message in 'perf stat' on hybrid
systems such as Intel Alder Lake.
- Add a dummy event on hybrid systems to collect metadata records.
- Add 24x7 nest metric events for the Power10 platform.
Fixes:
- Fix event parsing for PMUs starting with the same prefix.
- Fix the 'perf trace' 'trace' alias installation dir.
- Fix buffer size to report iregs in perf script python scripts,
supporting the extended registers in PowerPC.
- Fix overflow in elf_sec__is_text().
- Fix 's' on source line when disasm is empty in the annotation TUI,
accessible via 'perf annotate', 'perf report' and 'perf top'.
- Plug leaks in scandir() returned dirent entries in 'perf test' when
sorting the shell tests.
- Fix --task and --stat with pipe input in 'perf report'.
- Fix 'perf probe' use of debuginfo files by build id.
- If a DSO has both dynsym and symtab ELF sections, read from both
when loading the symbol table, fixing a problem processing Fedora
32 glibc DSOs.
Libraries:
- Add grouping of events to libperf, from code in tools/perf,
allowing libperf users to use that mode.

- Filter plt stubs from the 'perf probe --functions' output.
- Update UAPI header copies for asound, DRM, mman-common.h and the

deal with zero-sized percpu structures.
A superior workaround is achieved with commit a0b8200d06 ("kbuild:
skip per-CPU BTF generation for pahole v1.18-v1.21").
This patch reverts the dummy field and the pahole version check.
