This is the root interrupt controller used on Apple ARM SoCs such as the
M1. This irqchip driver performs multiple functions:
* Handles both IRQs and FIQs
* Drives the AIC peripheral itself (which handles IRQs)
* Dispatches FIQs to downstream hard-wired clients (currently the ARM
timer).
* Implements a virtual IPI multiplexer to funnel multiple Linux IPIs
into a single hardware IPI

These definitions are in arm-gic-v3.h for historical reasons which no
longer apply. Move them to sysreg.h so the AIC driver can use them, as
it needs to peek into vGIC registers to deal with the GIC maintentance
interrupt.

Now that we have ioremap_np(), we can make pci_remap_cfgspace() default
to it, falling back to ioremap() on platforms where it is not available.
Remove the arm64 implementation, since that is now redundant. Future
cleanups should be able to do the same for other arches, and eventually
make the generic pci_remap_cfgspace() unconditional.

ARM64 currently defaults to posted MMIO (nGnRE), but some devices
require the use of non-posted MMIO (nGnRnE). Introduce a new ioremap()
variant to handle this case. ioremap_np() returns NULL on arches that
do not implement this variant.
sparc64 is the only architecture that needs to be touched directly,
because it includes neither of the generic io.h or iomap.h headers.
This adds the IORESOURCE_MEM_NONPOSTED flag, which maps to this
variant and marks a given resource as requiring non-posted mappings.
This is implemented in the resource system because it is a SoC-level
requirement, so existing drivers do not need special-case code to pick
this ioremap variant.
Then this is implemented in devres by introducing devm_ioremap_np(),
and making devm_ioremap_resource() automatically select this variant
when the resource has the IORESOURCE_MEM_NONPOSTED flag set.

This allows the devicetree to correctly represent the available set of
timers, which varies from device to device, without the need for fake
dummy interrupts for unavailable slots.
Also add the hyp-virt timer/PPI, which is not currently used, but worth
representing.

Enhance enum nl80211_tdls_peer_capability to configure TDLS peer's
support for HE mode. Userspace decodes the TDLS setup response frame
and confugures the HE mode support to driver if the peer has advertized
HE mode support in TDLS setup response frame. The driver uses this
information to decide whether to include HE operation IE in TDLS setup
confirmation frame.

Allocate a new private stub fence in drm_syncobj_assign_null_handle,
instead of using a static stub fence.
When userspace creates a fence with DRM_SYNCOBJ_CREATE_SIGNALED or when
userspace signals a fence via DRM_IOCTL_SYNCOBJ_SIGNAL, the timestamp
obtained when the fence is exported and queried with SYNC_IOC_FILE_INFO
should match when the fence's status was changed from the perspective of
userspace, which is during the respective ioctl.
When a static stub fence started being used in by these ioctls, this
behavior changed. Instead, the timestamp returned by SYNC_IOC_FILE_INFO
became the first time anything used the static stub fence, which has no
meaning to userspace.

Recompiling with the new extended version of struct rfkill_event
broke systemd in *two* ways:
- It used "sizeof(struct rfkill_event)" to read the event, but
then complained if it actually got something != 8, this broke
it on new kernels (that include the updated API);
- It used sizeof(struct rfkill_event) to write a command, but
didn't implement the intended expansion protocol where the
kernel returns only how many bytes it accepted, and errored
out due to the unexpected smaller size on kernels that didn't
include the updated API.
Even though systemd has now been fixed, that fix may not be always
deployed, and other applications could potentially have similar
issues.
As such, in the interest of avoiding regressions, revert the
default API "struct rfkill_event" back to the original size.
Instead, add a new "struct rfkill_event_ext" that extends it by
the new field, and even more clearly document that applications
should be prepared for extensions in two ways:
* write might only accept fewer bytes on older kernels, and
will return how many to let userspace know which data may
have been ignored;
* read might return anything between 8 (the original size) and
whatever size the application sized its buffer at, indicating
how much event data was supported by the kernel.
Perhaps that will help avoid such issues in the future and we
won't have to come up with another version of the struct if we
ever need to extend it again.
Applications that want to take advantage of the new field will
have to be modified to use struct rfkill_event_ext instead now,
which comes with the danger of them having already been updated
to use it from 'struct rfkill_event', but I found no evidence
of that, and it's still relatively new.

TIOCSSERIAL is a horrid, underspecified, legacy interface which for most
serial devices is only useful for setting the close_delay and
closing_wait parameters.
The closing_wait parameter determines how long to wait for the transfer
buffers to drain during close and the default timeout of 30 seconds may
not be sufficient at low line speeds. In other cases, when for example
flow is stopped, the default timeout may instead be too long.
Add generic support for TIOCSSERIAL and TIOCGSERIAL with handling of the
three common parameters close_delay, closing_wait and line for the
benefit of all USB serial drivers while still allowing drivers to
implement further functionality through the existing callbacks.
This currently includes a few drivers that report their base baud clock
rate even if that is really only of interest when setting custom
divisors through the deprecated ASYNC_SPD_CUST interface; an interface
which only the FTDI driver actually implements.
Some drivers have also been reporting back a fake UART type, something
which should no longer be needed and will be dropped by a follow-on
patch.

but prints out a totally useless message that prevents effective debugging
especially when multiple transmit queues are being used.
Add a tx_timeout rdma_netdev hook and implement the callback in the hfi1
to print additional information.
The existing non-helpful message is avoided when the driver has presented
a callback.

Some drivers clear the 'ethtool_link_ksettings' struct in their
get_link_ksettings() callback, before populating it with actual values.
Such drivers will set the new 'link_mode' field to zero, resulting in
user space receiving wrong link mode information given that zero is a
valid value for the field.
Another problem is that some drivers (notably tun) can report random
values in the 'link_mode' field. This can result in a general protection
fault when the field is used as an index to the 'link_mode_params' array
[1].
This happens because such drivers implement their set_link_ksettings()
callback by simply overwriting their private copy of
'ethtool_link_ksettings' struct with the one they get from the stack,
which is not always properly initialized.
Fix these problems by removing 'link_mode' from 'ethtool_link_ksettings'
and instead have drivers call ethtool_params_from_link_mode() with the
current link mode. The function will derive the link parameters (e.g.,
speed) from the link mode and fill them in the 'ethtool_link_ksettings'
struct.
v3:
* Remove link_mode parameter and derive the link parameters in
the driver instead of passing link_mode parameter to ethtool
and derive it there.
v2:
* Introduce 'cap_link_mode_supported' instead of adding a
validity field to 'ethtool_link_ksettings' struct.

This returns the index in the supported_type_groups array that is
associated with the mdev_type attached to the struct mdev_device or its
containing struct kobject.
Each mdev_device can be spawned from exactly one mdev_type, which in turn
originates from exactly one supported_type_group.
Drivers are using weird string calculations to try and get back to this
index, providing a direct access to the index removes a bunch of wonky
driver code.
mdev_type->group can be deleted as the group is obtained using the
type_group_id.

This is only done once, we don't need to generate code to initialize a
structure stored in the ELF .data segment. Fill in the three required
.driver members directly instead of copying data into them during
mdev_register_driver().
Further the to_mdev_driver() function doesn't belong in a public header,
just inline it into the two places that need it. Finally, we can now
clearly see that 'drv' derived from dev->driver cannot be NULL, firstly
because the driver core forbids it, and secondly because NULL won't pass
through the container_of(). Remove the dead code.

The mdev API should accept and pass a 'struct mdev_device *' in all
places, not pass a 'struct device *' and cast it internally with
to_mdev_device(). Particularly in its struct mdev_driver functions, the
whole point of a bus's struct device_driver wrapper is to provide type
safety compared to the default struct device_driver.
Further, the driver core standard is for bus drivers to expose their
device structure in their public headers that can be used with
container_of() inlines and '&foo->dev' to go between the class levels, and
'&foo->dev' to be used with dev_err/etc driver core helper functions. Move
'struct mdev_device' to mdev.h
Once done this allows moving some one instruction exported functions to
static inlines, which in turns allows removing one of the two grotesque
symbol_get()'s related to mdev in the core code.

====================
mlx5-updates-2021-04-06
Introduce TC sample offload
Background
----------
The tc sample action allows user to sample traffic matched by tc
classifier. The sampling consists of choosing packets randomly and
sampling them using psample module.
The tc sample parameters include group id, sampling rate and packet's
truncation (to save kernel-user traffic).
Sample in TC SW
---------------
User must specify rate and group id for sample action, truncate is
optional.
tc filter add dev enp4s0f0_0 ingress protocol ip prio 1 flower \
src_mac 02:25:d0:14:01:02 dst_mac 02:25:d0:14:01:03 \
action sample rate 10 group 5 trunc 60 \
action mirred egress redirect dev enp4s0f0_1
The tc sample action kernel module 'act_sample' will call another
kernel module 'psample' to send sampled packets to userspace.
MLX5 sample HW offload - MLX5 driver patches
--------------------------------------------
The sample action is translated to a goto flow table object
destination which samples packets according to the provided
sample ratio. Sampled packets are duplicated. One copy is
processed by a termination table, named the sample table,
which sends the packet to the eswitch manager port (that will
be processed by software).
The second copy is processed by the default table which executes
the subsequent actions. The default table is created per <vport,
chain, prio> tuple as rules with different prios and chains may
overlap.
For example, for the following typical flow table:
+-------------------------------+
+ original flow table +
+-------------------------------+
+ original match +
+-------------------------------+
+ sample action + other actions +
+-------------------------------+
We translate the tc filter with sample action to the following HW model:
+---------------------+
+ original flow table +
+---------------------+
+ original match +
+---------------------+
|
v
+------------------------------------------------+
+ Flow Sampler Object +
+------------------------------------------------+
+ sample ratio +
+------------------------------------------------+
+ sample table id | default table id +
+------------------------------------------------+
| |
v v
+-----------------------------+ +----------------------------------------+
+ sample table + + default table per <vport, chain, prio> +
+-----------------------------+ +----------------------------------------+
+ forward to management vport + + original match +
+-----------------------------+ +----------------------------------------+
+ other actions +
+----------------------------------------+
Flow sampler object
-------------------
Hardware introduces flow sampler object to do sample. It is a new
destination type. Driver needs to specify two flow table ids in it.
One is sample table id. The other one is the default table id.
Sample table samples the packets according to the sample rate and
forward the sampled packets to eswitch manager port. Default table
finishes the subsequent actions.
Group id and reg_c0
-------------------
Userspace program will take different actions for sampled packets
according to tc sample action group id. So hardware must pass group
id to software for each sampled packets. In Paul Blakey's "Introduce
connection tracking offload" patch set, reg_c0 lower 16 bits are used
for miss packet chain id restore. We convert reg_c0 lower 16 bits to
a common object pool, so other features can also use it.
Since sample group id is 32 bits, create a 16 bits object id to map
the group id and write the object id to reg_c0 lower 16 bits. reg_c0
can only be used for matching. Write reg_c0 to flow_tag, so software
can get the object id via flow_tag and find group id via the common
object pool.
Sampler restore handle
----------------------
Use common object pool to create an object id to map sample parameters.
Allocate a modify header action to write the object id to reg_c0 lower
16 bits. Create a restore rule to pass the object id to software. So
software can identify sampled packets via the object id and send it to
userspace.
Aggregate the modify header action, restore rule and object id to a
sample restore handle. Re-use identical sample restore handle for
the same object id.
Send sampled packets to userspace
---------------------------------
The destination for sampled packets is eswitch manager port, so
representors can receive sampled packets together with the group id.
Driver will send sampled packets and group id to userspace via psample.

Extended link state structures and enums use kdoc headers
but then do not describe any of the members.
Convert to normal comments.

This patch moved the mptcp_addr_info struct from protocol.h to mptcp.h,
added a new struct mptcp_addr_info member addr in struct mptcp_out_options,
and dropped the original addr, addr6, addr_id and port fields in it. Then
we can use opts->addr to get the adding address from PM directly using
mptcp_pm_add_addr_signal.
Since the port number became big-endian now, use ntohs to convert it
before sending it out with the ADD_ADDR suboption. Also convert it
when passing it to add_addr_generate_hmac or printing it out.

Performance counts, and ALWAYS_ON counters used for capturing GPU
timestamps, lose their state across suspend/resume cycles. Userspace
tooling for performance monitoring needs to be aware of this. For
example, after a suspend userspace needs to recalibrate it's offset
between CPU and GPU time.

Subsequent changes will cause the exit_latency_ns and target_residency_ns
fields in struct cpuidle_state to be used in computations in which data
type conversions to u64 may turn a negative number close to zero into
a verly large positive number leading to incorrect results.
In preparation for that, change the data type of the fields mentioned
above to s64, but ensure that they will not be negative themselves.
No intentional functional impact.

ACPICA commit 8710a708faed728ea2672b8da842b2e9af1cf5bd
IORT revision E.b (ARM DEN 0049E.b) contains a few additions like,
-Added an identifier field in the node descriptors to aid table
cross-referencing.
-Introduced the Reserved Memory Range(RMR) node. This is used
to describe memory ranges that are used by endpoints and require
a unity mapping in SMMU.
-Introduced a flag in the RC node to express support for PRI.
-Added a flag in the RC node to declare support for PASID forward
information.
Please note that IORT Rev E and E.a have known issues and are not
supported.
