bee387131a Merge tag 'spi-nor/for-5.17' into mtd/next
SPI NOR core changes:
- Add Pratyush as SPI NOR co-maintainer.
- Flash parameters initialization was done in a spaghetti way. Clean
  flash parameters initialization.
- Rework the flash_info flags and clarify where one should be used.
- Initialize all flash parameters based on JESD216 SFDP where possible.
  Flash parameters and settings that are SFDP discoverable should not be
  duplicated via flash_info flags at flash declaration.
- Remove debugfs entries that duplicate sysfs entries.

SPI NOR manufacturer drivers changes:
- Use late_init() hook in various drivers to make it clear that those
  flash parameters are either not declared in the JESD216 SFDP standard,
  or the SFDP tables which define those flash parameters are not defined
  by the flash.
- Fix mtd size for s3an flashes.
- Write 2 bytes when disabling Octal DTR mode: 1 byte long transactions are
  not allowed in 8D-8D-8D mode.

Memory controller drivers for v5.17 - OMAP GPMC

1. Add support for AM64 SoC.
2. Minor improvement: use platform_get_irq().

[miquel.raynal@bootlin.com: A first commit introduced a new omap
compatible and another moved the IDs to a header which created a
conflict: moving the new ID as well in the header fixed it.]

4ff725e1d4 net/mlx5: DR, Ignore modify TTL if device doesn't support it
When modifying TTL, packet's csum has to be recalculated.
Due to HW issue in ConnectX-5, csum recalculation for modify TTL
is supported through a work-around that is specifically enabled
by configuration.
If the work-around isn't enabled, ignore the modify TTL action
rather than adding an unsupported action.

35f9e773bb ACPI / x86: Add acpi_quirk_skip_[i2c_client|serdev]_enumeration() helpers
x86 ACPI boards which ship with only Android as their factory image usually
declare a whole bunch of bogus I2C devs in their ACPI tables and sometimes
there are issues with serdev devices on these boards too, e.g. the resource
points to the wrong serdev_controller.

Instantiating I2C / serdev devs for these bogus devs causes various issues,
e.g. GPIO/IRQ resource conflicts because sometimes drivers do bind to them.
The Android x86 kernel fork shipped on these devices has some special code
to remove the bogus I2C clients (and serdevs are ignored completely).

Introduce acpi_quirk_skip_i2c_client_enumeration() and
acpi_quirk_skip_serdev_enumeration() helpers. Which can be used by the I2C/
serdev code to skip instantiating any I2C or serdev devs on broken boards.

These 2 helpers are added to drivers/acpi/x86/utils.c so that the DMI table
can be shared between the I2C and serdev code.

Note these boards typically do actually have I2C and serdev devices, just
different ones then the ones described in their DSDT. The devices which
are actually present are manually instantiated by the
drivers/platform/x86/x86-android-tablets.c kernel module.

The new helpers are only build if CONFIG_X86_ANDROID_TABLETS is enabled,
otherwise they are empty stubs to not unnecessarily grow the kernel size.

This element is optional. If supported, contains a resource descriptor
with a single Register() descriptor that describes a register to which
OSPM writes a One to enable CPPC on this processor. Before this register
is set, the processor will be controlled by legacy mechanisms (ACPI
Pstates, firmware, etc.).

This register will be used for AMD processors to enable AMD P-State
function instead of legacy ACPI P-States.

c18e276030 counter: Provide alternative counter registration functions
The current implementation gets device lifetime tracking wrong. The
problem is that allocation of struct counter_device is controlled by the
individual drivers but this structure contains a struct device that
might have to live longer than a driver is bound. As a result a command
sequence like:

	{ sleep 5; echo bang; } > /dev/counter0 &
	sleep 1;
	echo 40000000.timer:counter > /sys/bus/platform/drivers/stm32-timer-counter/unbind

can keep a reference to the struct device and unbinding results in
freeing the memory occupied by this device resulting in an oops.

This commit provides two new functions (plus some helpers):
 - counter_alloc() to allocate a struct counter_device that is
   automatically freed once the embedded struct device is released
 - counter_add() to register such a device.

Note that this commit doesn't fix any issues, all drivers have to be
converted to these new functions to correct the lifetime problems.

d8e9a406a9 serdev: BREAK/FRAME/PARITY/OVERRUN notification prototype V2
Allow serdev device drivers get notified by hardware errors such as BREAK,
FRAME, PARITY and OVERRUN.

With this patch, in the event of an error detected in the UART device driver
the serdev_device_driver will get the newly introduced ->error() callback
invoked if serdev_device_set_error_mask() has previously been used to enable
the type of error. The errors are taken straight from the TTY layer and fed
into the serdev_device_driver after filtering out only enabled errors.

Without this patch the hardware errors never reach the serdev_device_driver.

b4a29b9480 serial: 8250: Move Alpha-specific quirk out of the core
struct uart_8250_port contains mcr_mask and mcr_force members whose
sole purpose is to work around an Alpha-specific quirk.  This code
doesn't belong in the core where it is executed by everyone else,
so move it to a proper ->set_mctrl callback which is used on the
affected Alpha machine only.

The quirk was introduced in January 1995:
https://git.kernel.org/pub/scm/linux/kernel/git/history/history.git/diff/drivers/char/serial.c?h=1.1.83

The members in struct uart_8250_port were added in 2002:
https://git.kernel.org/history/history/c/4524aad27854

The quirk applies to non-PCI Alphas and arch/alpha/Kconfig specifies
"select FORCE_PCI if !ALPHA_JENSEN".  So apparently the only affected
machine is the EISA-based Jensen that Linus was working on back then:
https://lore.kernel.org/all/CAHk-=wj1JWZ3sCrGz16nxEj7=0O+srMg6Ah3iPTDXSPKEws_SA@mail.gmail.com/

Up until now the quirk is not applied unless CONFIG_PCI is disabled.
If users forget to do that or run a generic Alpha kernel, the serial
ports aren't usable on Jensen.  Avoid by confining the quirk to
CONFIG_ALPHA_JENSEN instead of !CONFIG_PCI.  On generic Alpha kernels,
auto-detect at runtime whether the quirk needs to be applied.

730b49aac4 usb: typec: port-mapper: Convert to the component framework
Instead of trying to keep track of the connections to the
USB Type-C connectors separately, letting the component
framework take care of that.

From now on every USB Type-C connector will register itself
as "aggregate" - component master - and anything that can be
connected to it inside the system can then simply register
itself as a generic component.

The matching of the components and the connector shall rely
on ACPI _PLD initially. Before registering itself as the
aggregate, the connector will find all other ACPI devices
that have matching _PLD crc hash with it (matching value in
the pld_crc member of struct acpi_device), and add a
component match entry for each one of them. Because only
ACPI is supported for now, the driver shall only be build
when ACPI is supported.

This removes the need for the custom API that the driver
exposed. The components and the connector can therefore
exist completely independently of each other. The order in
which they are registered, as well as are they modules or
not, is now irrelevant.

Storing CRC-32 hash of the Physical Location of Device
object (_PLD) with devices that have it. The hash is stored
to a new struct acpi_device member "pld_crc".

The hash makes it easier to find devices that share a
location, as there is no need to evaluate the entire object
every time. Knowledge about devices that share a location
can be used in device drivers that need to know the
connections to other components inside a system. USB3 ports
will for example always share their location with a USB2
port.

aebb51ec3d bpf: Invert the dependency between bpf-netns.h and netns/bpf.h
netns/bpf.h gets included by netdevice.h (thru net_namespace.h)
which in turn gets included in a lot of places. We should keep
netns/bpf.h as light-weight as possible.

bpf-netns.h seems to contain more implementation details than
deserves to be included in a netns header. It needs to pull in
uapi/bpf.h to get various enum types.

Move enum netns_bpf_attach_type to netns/bpf.h and invert the
dependency. This makes netns/bpf.h fit the mold of a struct
definition header more clearly, and drops the number of objects
rebuilt when uapi/bpf.h is touched from 7.7k to 1.1k.

0fe4b381a5 bpf: Allow bpf_local_storage to be used by sleepable programs
Other maps like hashmaps are already available to sleepable programs.
Sleepable BPF programs run under trace RCU. Allow task, sk and inode
storage to be used from sleepable programs. This allows sleepable and
non-sleepable programs to provide shareable annotations on kernel
objects.

Sleepable programs run in trace RCU where as non-sleepable programs run
in a normal RCU critical section i.e.  __bpf_prog_enter{_sleepable}
and __bpf_prog_exit{_sleepable}) (rcu_read_lock or rcu_read_lock_trace).

In order to make the local storage maps accessible to both sleepable
and non-sleepable programs, one needs to call both
call_rcu_tasks_trace and call_rcu to wait for both trace and classical
RCU grace periods to expire before freeing memory.

Paul's work on call_rcu_tasks_trace allows us to have per CPU queueing
for call_rcu_tasks_trace. This behaviour can be achieved by setting
rcupdate.rcu_task_enqueue_lim=<num_cpus> boot parameter.

In light of these new performance changes and to keep the local storage
code simple, avoid adding a new flag for sleepable maps / local storage
to select the RCU synchronization (trace / classical).

Also, update the dereferencing of the pointers to use
rcu_derference_check (with either the trace or normal RCU locks held)
with a common bpf_rcu_lock_held helper method.

As we defined the new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX

Let's define the new flag so user space could build it on old kernel with

b6459415b3 net: Don't include filter.h from net/sock.h
sock.h is pretty heavily used (5k objects rebuilt on x86 after
it's touched). We can drop the include of filter.h from it and
add a forward declaration of struct sk_filter instead.
This decreases the number of rebuilt objects when bpf.h
is touched from ~5k to ~1k.

There's a lot of missing includes this was masking. Primarily
in networking tho, this time.

b0013e037a ACPI: Introduce Platform Firmware Runtime Telemetry driver
This driver allows user space to fetch telemetry data from the
firmware with the help of the Platform Firmware Runtime Telemetry
interface.

Both PFRU and PFRT are based on ACPI _DSM interfaces located under
special device objects in the ACPI Namespace, but these interfaces
are different from each other, so it is better to provide a separate
driver from each of them, even though they share some common
definitions and naming conventions.

0db89fa243 ACPI: Introduce Platform Firmware Runtime Update device driver
Introduce the pfr_update driver which can be used for Platform Firmware
Runtime code injection and driver update [1].

The user is expected to provide the EFI capsule, and pass it to the
driver by writing the capsule to a device special file. The capsule
is transferred by the driver to the platform firmware with the help
of an ACPI _DSM method under the special ACPI Platform Firmware
Runtime Update device (INTC1080), and the actual firmware update is
carried out by the low-level Management Mode code in the platform
firmware.

This change allows certain pieces of the platform firmware to be
updated on the fly while the system is running (runtime) without the
need to restart it, which is key in the cases when the system needs to
be available 100% of the time and it cannot afford the downtime related
to restarting it, or when the work carried out by the system is
particularly important, so it cannot be interrupted, and it is not
practical to wait until it is complete.

1882de7fc5 efi: Introduce EFI_FIRMWARE_MANAGEMENT_CAPSULE_HEADER and corresponding structures
Platform Firmware Runtime Update image starts with UEFI headers, and the
headers are defined in UEFI specification, but some of them have not been
defined in the kernel yet.

For example, the header layout of a capsule file looks like this:

EFI_CAPSULE_HEADER
EFI_FIRMWARE_MANAGEMENT_CAPSULE_HEADER
EFI_FIRMWARE_MANAGEMENT_CAPSULE_IMAGE_HEADER
EFI_FIRMWARE_IMAGE_AUTHENTICATION

These structures would be used by the Platform Firmware Runtime Update
driver to parse the format of capsule file to verify if the corresponding
version number is valid. In this way, if the user provides an invalid
capsule image, the kernel could be used as a guard to reject it, without
switching to the Management Mode (which might be costly).

EFI_CAPSULE_HEADER has been defined in the kernel, but the other
structures have not been defined yet, so do that. Besides,
EFI_FIRMWARE_MANAGEMENT_CAPSULE_HEADER and
EFI_FIRMWARE_MANAGEMENT_CAPSULE_IMAGE_HEADER are required to be packed
in the uefi specification. For this reason, use the __packed attribute
to indicate to the compiler that the entire structure can appear
misaligned in memory (as suggested by Ard) in case one of them follows
the other directly in a capsule header.

The byte length of the Data field in the AEST Processor generic resource

However, it is defined as a pointer type, and on a 64-bit machine,
it is interpreted as 8 bytes. Therefore, it is changed from a pointer

This macro was only ever used when stuffing pointers into physical

implementation-defined as to whether that can be done. Now that all such
operations are gone, the macro is unused, and should be removed to avoid
such practices being reintroduced.

5d6e59665d ACPICA: Use original pointer for virtual origin tables
ACPICA commit dfa3feffa8f760b686207d09dc880cd2f26c72af

Currently the pointer to the table is cast to acpi_physical_address and
later cast back to a pointer to be dereferenced. Whether or not this is
supported is implementation-defined.

On CHERI, and thus Arm's experimental Morello prototype architecture,
pointers are represented as capabilities, which are unforgeable bounded
pointers, providing always-on fine-grained spatial memory safety. This
means that any pointer cast to a plain integer will lose all its
associated metadata, and when cast back to a pointer it will give a
null-derived pointer (one that has the same metadata as null but an
address equal to the integer) that will trap on any dereference. As a
result, this is an implementation where acpi_physical_address cannot be
used as a hack to store real pointers.

Thus, alter the lifecycle of table descriptors. Internal physical tables
keep the current behaviour where only the address is set on install, and
the pointer is set on acquire. Virtual tables (internal and external)
now store the pointer on initialisation and use that on acquire (which
will redundantly set *table_ptr to itself, but changing that is both
unnecessary and overly complicated as acpi_tb_acquire_table is called with
both a pointer to a variable and a pointer to Table->Pointer itself).

This requires propagating the (possible) table pointer everywhere in
order to make sure pointers make it through to acpi_tb_acquire_temp_table,
which requires a change to the acpi_install_table interface. Instead of
taking an ACPI_PHYSADDR_TYPE and a boolean indicating whether it's
physical or virtual, it is now split into acpi_install_table (that takes
an external virtual table pointer) and acpi_install_physical_table (that
takes an ACPI_PHYSADDR_TYPE for an internal physical table address).
This also has the benefit of providing a cleaner API.

ca25f92b72 ACPICA: Use original data_table_region pointer for accesses
ACPICA commit d9eb82bd7515989f0b29d79deeeb758db4d6529c

later cast back to a pointer to be dereferenced. Whether or not this is

Thus, add a new field to struct acpi_object_region to store the pointer for
table regions, and propagate it to acpi_ex_data_table_space_handler via the
region context, to use a more portable implementation that supports
CHERI.

Rather than adding more magic numbers, add ACPI_ACCESS_*_SHIFT,

redefine ACPI_ACCESS_*_WIDTH in terms of the new #defines.

This was inititally reported on Linux where a size of 102 in
