All users of pci_vpd_find_info_keyword() are interested in the VPD RO
section only. In addition all calls are followed by the same activities to
calculate start of tag data area and size of the data area.
Add pci_vpd_find_ro_info_keyword() that combines these functionalities.
pci_vpd_find_info_keyword() can be phased out once all users are converted.

Several users of the VPD API use a fixed-size buffer and read the VPD into
it for further usage. This requires special handling for the case that the
buffer isn't big enough to hold the full VPD data. Also the buffer is
often allocated on the stack, which isn't too nice.
Add pci_vpd_alloc() to dynamically allocate buffer of the correct size and
read VPD into it.

Exporting sysfs files that can't be accessed doesn't make much sense.
Therefore, if either a quirk or the dynamic size calculation result in VPD
being marked as invalid, treat this as though the device has no VPD
capability. One consequence is that the "vpd" sysfs file is not visible.

Some multi-function devices share VPD hardware across functions and don't
work correctly for concurrent VPD accesses to different functions.
Struct pci_vpd_ops was added by 932c435cab ("PCI: Add dev_flags bit to
access VPD through function 0") so that on these devices, VPD accesses to
any function would always go to function 0.
It's easier to just check for the PCI_DEV_FLAGS_VPD_REF_F0 quirk bit in the
two places we need it than to deal with the struct pci_vpd_ops.
Simplify the code by removing struct pci_vpd_ops and removing the indirect
calls.

Reading/writing 4 bytes should be fast enough even on a slow bus, therefore
pci_vpd_wait() doesn't have to be interruptible. Making it uninterruptible
allows to simplify the code.
In addition make VPD writes uninterruptible in general. It's about vital
data, and allowing writes to be interruptible may leave the VPD in an
inconsistent state.

vpd->len is initialized to PCI_VPD_MAX_SIZE, and if a quirk is used to set
a specific VPD size, then pci_vpd_set_size() sets vpd->valid, resulting in
pci_vpd_size() not being called. Therefore we can remove the old_size
argument. Note that we don't have to check off < PCI_VPD_MAX_SIZE because
that's implicitly done by pci_read_vpd().

Previously, if we found any error in the VPD, we returned size 0, which
prevents access to all of VPD. But there may be valid resources in VPD
before the error, and there's no reason to prevent access to those.
"off" covers only VPD resources known to have valid header tags. In case
of error, return "off" (which may be zero if we haven't found any valid
header tags at all).

VPD consists of a series of Small and Large Resources. Computing the size
of VPD requires only the length of each, which is specified in the generic
tag of each resource. We only expect to see ID_STRING, RO_DATA, and
RW_DATA in VPD, but it's not a problem if it contains other resource types
because all we care about is the size.
Drop the validity checking of Large Resource items.

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)

Pull ARM devicetree updates from Olof Johansson:
"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
5/5II
- TI K3: PCI/USB3 support on AM64-sk boards, R5 remoteproc
definitions
- TI OMAP: Various cleanups
- Tegra: Audio support for Jetson Xavier NX, SMMU support on Tegra194
- Qualcomm: lots of additions for peripherals across several SoCs,
and new support for Microsoft Surface Duo (SM8150-based), Huawei
Ascend G7.
- i.MX: Numerous additions of features across SoCs and boards.
- Allwinner: More device bindings for V3s, Forlinx OKA40i-C and
NanoPi R1S H5 boards
- MediaTek: More device bindings for mt8167, new Chromebook system
variants for mt8183
- Renesas: RZ/G2L SoC and EVK added
- Amlogic: BananaPi BPI-M5 board added"

Pull ARM SoC updates from Olof Johansson:
"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 memblock fix from Mike Rapoport:
"This is a fix for the rework of ARM's pfn_valid() implementation
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.
Use memblock_is_map_memory() instead of pfn_valid() to check if a PFN
is in RAM or not"

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"

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.
