f9e109a209 mtd: mtdconcat: Judge callback existence based on the master
Since commit 46b5889cc2c5("mtd: implement proper partition handling")
applied, mtd partition device won't hold some callback functions, such
as _block_isbad, _block_markbad, etc. Besides, function mtd_block_isbad()
will get mtd device's master mtd device, then invokes master mtd device's
callback function. So, following process may result mtd_block_isbad()
always return 0, even though mtd device has bad blocks:

1. Split a mtd device into 3 partitions: PA, PB, PC
[ Each mtd partition device won't has callback function _block_isbad(). ]
2. Concatenate PA and PB as a new mtd device PN
[ mtd_concat_create() finds out each subdev has no callback function
_block_isbad(), so PN won't be assigned callback function
concat_block_isbad(). ]
Then, mtd_block_isbad() checks "!master->_block_isbad" is true, will
always return 0.

Reproducer:
// reproduce.c
static int __init init_diy_module(void)
{
	struct mtd_info *mtd[2];
	struct mtd_info *mtd_combine = NULL;

	mtd[0] = get_mtd_device_nm("NAND simulator partition 0");
	if (!mtd[0]) {
		pr_err("cannot find mtd1\n");
		return -EINVAL;
	}
	mtd[1] = get_mtd_device_nm("NAND simulator partition 1");
	if (!mtd[1]) {
		pr_err("cannot find mtd2\n");
		return -EINVAL;
	}

	put_mtd_device(mtd[0]);
	put_mtd_device(mtd[1]);

	mtd_combine = mtd_concat_create(mtd, 2, "Combine mtd");
	if (mtd_combine == NULL) {
		pr_err("combine failed\n");
		return -EINVAL;
	}

	mtd_device_register(mtd_combine, NULL, 0);
	pr_info("Combine success\n");

	return 0;

60d0607998 mtd: maps: remove dead MTD map driver for PMC-Sierra MSP boards
Commit 1b00767fd8 ("MIPS: Remove PMC MSP71xx platform") removes the
config PMC_MSP in ./arch/mips/Kconfig.

Hence, since then, the corresponding MTD map driver for PMC-Sierra MSP
boards is dead code. Remove this dead driver.

a3a447848a mtd: rfd_ftl: add discard support
I proposed this change 16 years ago before discard was a feature in
the block layer: https://lwn.net/Articles/162776/

Now that the block layer has discard, we can finally merge this change.

Discard is also known as trim. By implementing discard, both fstrim and
the discard filesystem option can be used.

Implementing discard in the ftl means that when files are removed, there
is less data in the ftl mapping. This means less stuff to move around for
erasing and also less erasing to do; this means improved wear levelling
and improved performance.

e07403a8c6 mtdblock: Warn if added for a NAND device
There is a surprisingly large number of tutorials
that suggest using mtdblock to mount SquashFS filesystems
on flash devices, including NAND devices.

This approach is suboptimal than using UBI. If the flash device
is NAND, this is specially true, due to wear leveling, bit-flips and
badblocks. In this case UBI is strongly preferred, so be nice to users
and print a warning suggesting to consider UBI block, if mtdblock
is added for a NAND device.

There is a surprisingly large number of tutorials
that suggest using mtdblock to mount SquashFS filesystems
on flash devices, including NAND devices.

Given this approach is suboptimal than using UBI, and given
the UBI block device layer was introduced many years ago
specifically with this use case in mind, add a small
comment inviting users and developers to consider UBI block.

6bc219b7b2 mtdblock: Update old JFFS2 mention in Kconfig
JFFS2 can be mounted without 'mtdblock' since
a really, really long time. Some git-log
archaeology shows that in 2006 it was possible
to use 'root=' to mount a JFFS2 rootfs:

  commit e9482b4374
  Author: Joern Engel <joern@wh.fh-wedel.de>
  Date:   Tue May 30 14:25:46 2006 +0200

      [MTD] Allow alternate JFFS2 mount variant for root filesystem.

      With this patch, "root=mtd3" and "root=mtd:foo" work for a JFFS2 rootfs.

However, there are still plenty of tutorials that mention
mtdblock, so users are still taking this route. Update the Kconfig
to reflect this is no longer needed.

023e1a8dd5 mm/rmap: fix new bug: premature return from page_mlock_one()
In the unlikely race case that page_mlock_one() finds VM_LOCKED has been
cleared by the time it got page table lock, page_vma_mapped_walk_done()
must be called before returning, either explicitly, or by a final call
to page_vma_mapped_walk() - otherwise the page table remains locked.

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)

64b586d192 mm/rmap: fix comments left over from recent changes

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).

8b9cc17a46 SCSI misc on 20210711
This is a set of minor fixes and clean ups in the core and various
 drivers.  The only core change in behaviour is the I/O retry for
 spinup notify, but that shouldn't impact anything other than the
 failing case.

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 dbbee9d5cd ("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 a0b8200d06 ("kbuild:
skip per-CPU BTF generation for pahole v1.18-v1.21").

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

 "Like always, the DT branch is sizable. There are numerous additions
  and fixes to existing platforms, but also a handful of new ones
  introduced. Less than some other releases, but there's been
  significant work on cleanups, refactorings and device enabling on
  existing platforms.

  A non-exhaustive list of new material:

   - Refactoring of BCM2711 dtsi structure to add support for the
     Raspberry Pi 400

   - Rockchip: RK3568 SoC and EVB, video codecs for
     rk3036/3066/3188/322x

   - Qualcomm: SA8155p Automotive platform (SM8150 derivative),
     SM8150/8250 enhancements and support for Sony Xperia 1/1II and

6e207b8821 ARM: SoC changes for 5.14
A few SoC (code) changes have queued up this cycle, mostly for minor
 changes and some refactoring and cleanup of legacy platforms. This
 branch also contains a few of the fixes that weren't sent in by the end
 of the release (all fairly minor).
 
  - Adding an additional maintainer for the TEE subsystem (Sumit Garg)
 
  - Quite a significant modernization of the IXP4xx platforms by Linus
    Walleij, revisiting with a new PCI host driver/binding, removing legacy
    mach/* include dependencies and moving platform detection/config to
    drivers/soc. Also some updates/cleanup of platform data.
 
  - Core power domain support for Tegra platforms, and some improvements
    in build test coverage by adding stubs for compile test targets.
 
  - A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP
    support on i.MX7D, SoC ID setup for i.MX50, removal of platform data
    and board fixups for iMX6/7.
 
  ... and a few smaller changes and fixes for Samsung, OMAP, Allwinner,
  Rockchip.

Pull percpu fix from Dennis Zhou:
 "This is just a single change to fix percpu depopulation. The code
  relied on depopulation code written specifically for the free path and
  relied on vmalloc to do the tlb flush lazily. As we're modifying the
  backing pages during the lifetime of a chunk, we need to also flush
  the tlb accordingly.

  Guenter Roeck reported this issue in [1] on mips. I believe we just
  happen to be lucky given the much larger chunk sizes on x86 and
  consequently less churning of this memory"

2f86198467 rtc: pcf2127: handle timestamp interrupts
commit 03623b4b04 ("rtc: pcf2127: add tamper detection support")
added support for timestamp interrupts. However they are not being
handled in the irq handler. If a timestamp interrupt occurs it
results in kernel disabling the interrupt and displaying the call
trace:

[  121.145580] irq 78: nobody cared (try booting with the "irqpoll" option)
...
[  121.238087] [<00000000c4d69393>] irq_default_primary_handler threaded [<000000000a90d25b>] pcf2127_rtc_irq [rtc_pcf2127]
[  121.248971] Disabling IRQ #78

Handle timestamp interrupts in pcf2127_rtc_irq(). Save time stamp
before clearing TSF1 and TSF2 flags so that it can't be overwritten.
Set a flag to mark if the timestamp is valid and only report to sysfs
if the flag is set. To mimic the hardware behavior, don’t save
another timestamp until the first one has been read by the userspace.

However, if the alarm irq is not configured, keep the old way of
handling timestamp interrupt in the timestamp0 sysfs calls.

The offset variable is checked by at91_rtc_readalarm(), but this check
is unnecessary because the previous check knew that the value of this

This removes that unnecessary offset variable checks.
