cbe63bfdc5 clk: qcom: Add Global Clock controller (GCC) driver for SM6115
Add support for the global clock controller found on SM6115
based devices. This should allow most non-multimedia device
drivers to probe and control their clocks.

Based on CAF implementation. GDSCs ported from downstream DT.

da09577ab5 clk: qcom: gcc-sdm660: Replace usage of parent_names
Using parent_data and parent_hws, instead of parent_names, does protect
against some cases of incompletely defined clock trees. While it turns
out that the bug being chased this time was totally unrelated, this
patch converts the SDM660 GCC driver to avoid such issues.

The "xo" fixed_factor clock is unused within the gcc driver, but
referenced from the DSI PHY. So it's left in place until the DSI driver
is updated.

a649136b17 PM: runtime: add devm_pm_clk_create helper
A typical code pattern for pm_clk_create() call is to call it in the
_probe function and to call pm_clk_destroy() both from _probe error path
and from _remove function. For some drivers the whole remove function
would consist of the call to pm_remove_disable().

Add helper function to replace this bolierplate piece of code. Calling

in the probe()'s error path and in the remove() function.

5d9bc010db clk: qcom: a53-pll: Add MSM8939 a53pll support
MSM8939 has 3 a53pll clocks with different frequency table for Cluster0,
Cluster1 and CCI.  It adds function qcom_a53pll_get_freq_tbl() to create
pll_freq_tbl from OPP, so that those a53pll frequencies can be defined
in DT with operating-points-v2 bindings rather than being coded in the
driver.  In this case, one compatible rather than three would be needed
for these 3 a53pll clocks.

05cc560c8c clk: qcom: a53pll/mux: Use unique clock name
Different from MSM8916 which has only one a53pll/mux clock, MSM8939 gets
three for Cluster0 (little cores), Cluster1 (big cores) and CCI (Cache
Coherent Interconnect).  That said, a53pll/mux clock needs to be named
uniquely.  Append @unit-address of device node to the clock name, so
that a53pll/mux will be named like below on MSM8939.

  a53pll@b016000
  a53pll@b116000
  a53pll@b1d0000

  a53mux@b1d1000

0dfe9bf91f clk: qcom: apcs-msm8916: Flag a53mux instead of a53pll as critical
The clock source for MSM8916 cpu cores is like below.

                        |\
         a53pll --------| \ a53mux     +------+
                        | |------------| cpus |
     gpll0_vote --------| /            +------+
                        |/

So a53mux rather than a53pll is actually the parent clock of cpu cores.
It makes more sense to flag a53mux as critical instead, so that when
either a53pll or gpll0_vote is used by cpu cores, the clock will be kept
enabled while the other can be disabled.

d9770fcc1c mm/rmap: fix old bug: munlocking THP missed other mlocks
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: 9a73f61bdb8a ("thp, mlock: do not mlock PTE-mapped file huge pages")

64b586d192 mm/rmap: fix comments left over from recent changes
Parallel developments in mm/rmap.c have left behind some out-of-date
comments: try_to_migrate_one() also accepts TTU_SYNC (already commented
in try_to_migrate() itself), and try_to_migrate() returns nothing at
all.

TTU_SPLIT_FREEZE has just been deleted, so reword the comment about it
in mm/huge_memory.c; and TTU_IGNORE_ACCESS was removed in 5.11, so
delete the "recently referenced" comment from try_to_unmap_one() (once
upon a time the comment was near the removed codeblock, but they drifted
apart).

b1412bd75a perf tools changes for v5.14: 2nd batch
New features:
 
 - Enable use of BPF counters with 'perf stat --for-each-cgroup', using per-CPU
   'cgroup-switch' events with an attached BPF program 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.
 
 Misc:
 
 - Filter plt stubs from the 'perf probe --functions' output.
 
 - Update UAPI header copies for asound, DRM, mman-common.h and the ones
   affected by the quotactl_fd syscall.

6bce244390 mm/page_alloc: Revert pahole zero-sized workaround
Commit dbbee9d5cd83 ("mm/page_alloc: convert per-cpu list protection to
local_lock") folded in a workaround patch for pahole that was unable to
deal with zero-sized percpu structures.

A superior workaround is achieved with commit a0b8200d06ad ("kbuild:
skip per-CPU BTF generation for pahole v1.18-v1.21").

This patch reverts the dummy field and the pahole version check.

4aa90c036d rtc: pcf8523: rename register and bit defines
arch/arm/mach-ixp4xx/include/mach/platform.h now gets included indirectly
and defines REG_OFFSET. Rename the register and bit definition to something
specific to the driver.
