iio: adc: fsl-imx25-gcq: adjust irq check to match docs and simplify code
For the function of platform_get_irq(), the example in platform.c is
* int irq = platform_get_irq(pdev, 0);
* if (irq < 0)
* return irq;
the return value of zero is unnecessary to check, so make the right
check and simplify code.
Note that platform_get_irq() is documented as never returning 0
so this is a minor optmization rather than a fix.

iio: core: Support reading extended name as label
The point of this new change is to make the IIO tree actually parsable.
Before, given this attribute as a filename:
in_voltage0_aux_sample_rate
Userspace had no way to know if the attribute name was
"aux_sample_rate" with no extended name, or "sample_rate" with "aux" as
the extended name, or just "rate" with "aux_sample" as the extended
name.
This was somewhat possible to deduce when there was more than one
attribute present for a given channel, e.g:
in_voltage0_aux_sample_rate
in_voltage0_aux_frequency
There, it was possible to deduce that "aux" was the extended name. But
even with more than one attribute, this wasn't very robust, as two
attributes starting with the same prefix (e.g. "sample_rate" and
"sample_size") would result in the first part of the prefix being
interpreted as being part of the extended name.
To address the issue, knowing that channels will never have both a label
and an extended name, set the channel's label to the extended name.
In this case, the label's attribute will also have the extended name in
its filename, but we can live with that - userspace can open
in_voltage0_<prefix>_label and verify that it returns <prefix> to obtain
the extended name.

iio: accel: bma220: make suspend state setting more robust
The datasheet mentions that the suspend mode is toggled by reading the
suspend register. The reading returns value 0xFF if the system was in
suspend mode, otherwise it returns value 0x00.
The bma220_deinit() function does up to 2 reads, in case the device was in
suspend mode, which suggests a level of paranoia that makes the logic in
bma220_suspend() and bma220_resume() look insufficient.
This change implements a bma220_power() function which does up to 2 reads
of the suspend register to make sure that the chip enters a desired
(suspended or normal) mode.
If the transition fails, then -EBUSY is returned.
Since only a reference to SPI device is required, we can remove the
spi_set_drvdata() call and get the SPI device object from the base device
object in the suspend/resume routines.

The bma220_deinit() is converted into a callback for a

the driver gets uninitialized.
The return value of the bma220_deinit() function isn't used as it does not

override the actual error with -EBUSY, or can even return 0 (no error), on

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)

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

- Add Topdown metrics L2 events as default events in 'perf stat' for

merged during this merge window.
Don't abuse pfn_valid() to check if pfn is in RAM
The semantics of pfn_valid() is to check presence of the memory map
for a PFN and not whether a PFN is in RAM. The memory map may be
present for a hole in the physical memory and if such hole corresponds
to an MMIO range, __arm_ioremap_pfn_caller() will produce a WARN() and
fail.

"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

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"

rtc: pcf2127: handle timestamp interrupts
commit
03623b4b041c ("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.
