b65700d046 remoteproc: move rproc_da_to_va declaration to remoteproc.h
The rproc_da_to_va() API is an exported function, so move its
declaration from the remoteproc local remoteproc_internal.h
to the public remoteproc.h file.

This will allow drivers outside of the remoteproc folder to be
able to use this API.

nothing will have to resort to probe defering, as this is the main pillar

The example includes a board-specific compatible property, this is wrong

ef8795f3f1 dt-bindings: kbuild: Use DTB files for validation
Switch the DT validation to use DTB files directly instead of a DTS to
YAML conversion.

The original motivation for supporting validation on DTB files was to
enable running validation on a running system (e.g. 'dt-validate
/sys/firmware/fdt') or other cases where the original source DTS is not
available.

The YAML format was not without issues. Using DTBs with the schema type
information solves some of those problems. The YAML format relies on the
DTS source level information including bracketing of properties, size
directives, and phandle tags all of which are lost in a DTB file. While
standardizing the bracketing is a good thing, it does cause a lot of
extra warnings and churn to fix them.

Another issue has been signed types are not validated correctly as sign
information is not propagated to YAML. Using the schema type information
allows for proper handling of signed types. YAML also can't represent
the full range of 64-bit integers as numbers are stored as floats by
most/all parsers.

The DTB validation works by decoding property values using the type
information in the schemas themselves. The main corner case this does
not work for is matrix types where neither dimension is fixed. For
now, checking the dimensions in these cases are skipped.

380af29b8d tracing: Add snapshot at end of kernel boot up
Add ftrace_boot_snapshot kernel parameter that will take a snapshot at the
end of boot up just before switching over to user space (it happens during
the kernel freeing of init memory).

This is useful when there's interesting data that can be collected from
kernel start up, but gets overridden by user space start up code. With
this option, the ring buffer content from the boot up traces gets saved in
the snapshot at the end of boot up. This trace can be read from:

 /sys/kernel/tracing/snapshot

b3bc8547d3 tracing: Have TRACE_DEFINE_ENUM affect trace event types as well
The macro TRACE_DEFINE_ENUM is used to convert enums in the kernel to
their actual value when they are exported to user space via the trace
event format file.

Currently only the enums in the "print fmt" (TP_printk in the TRACE_EVENT
macro) have the enums converted. But the enums can be used to denote array
size:

        field:unsigned int fc_ineligible_rc[EXT4_FC_REASON_MAX]; offset:12;      size:36;        signed:0;

The EXT4_FC_REASON_MAX has no meaning to userspace but it needs to know
that information to know how to parse the array.

Have the array indexes also be parsed as well.

There's no reason to use strncpy here, in fact there's no reason to do

7e348b325b user_events: Prevent dyn_event delete racing with ioctl add/delete
Find user_events always while under the event_mutex and before leaving
the lock, add a ref count to the user_event. This ensures that all paths
under the event_mutex that check the ref counts will be synchronized.

The ioctl add/delete paths are protected by the reg_mutex. However,
dyn_event is only protected by the event_mutex. The dyn_event delete
path cannot acquire reg_mutex, since that could cause a deadlock between
the ioctl delete case acquiring event_mutex after acquiring the reg_mutex.

953c2f0521 tracing: Add sample code for custom trace events
Add sample code to show how to create custom trace events in the tracefs
directory that can be enabled and modified like any event in tracefs
(including triggers, histograms, synthetic events and event probes).

The example is creating a custom sched_switch and a sched_waking to limit
what is recorded:

If the custom sched switch only records the prev_prio, next_prio and
next_pid, it can bring the size from 64 bytes per event, down to just 16
bytes!

If sched_waking only records the prio and pid of the woken event, it will
bring the size down from 36 bytes to 12 bytes per event.

This will allow for a much smaller footprint into the ring buffer and keep
more events from dropping.

d33bd757d3 gtp: Implement GTP echo request
Adding GTP device through ip link creates the situation where
GTP instance is not able to send GTP echo requests.
Echo requests are used to check if GTP peer is still alive.
With this patch, gtp_genl_ops are extended by new cmd (GTP_CMD_ECHOREQ)
which allows to send echo request in the given version of GTP
protocol (v0 or v1), from the given ms address to he given
peer. TID is not inclued because in all path management
messages it should be equal to 0.

When GTP echo response is detected, multicast message is
send to everyone in the gtp_genl_family. Message contains
GTP version, ms address and peer address.

should contain information element with GTPIE_RECOVERY tag and
restart counter value. For GTPv1 restart counter is not used

b20dc3c684 gtp: Allow to create GTP device without FDs
Currently, when the user wants to create GTP device, he has to
provide file handles to the sockets created in userspace (IFLA_GTP_FD0,
IFLA_GTP_FD1). This behaviour is not ideal, considering the option of
adding support for GTP device creation through ip link. Ip link
application is not a good place to create such sockets.

This patch allows to create GTP device without providing
IFLA_GTP_FD0 and IFLA_GTP_FD1 arguments. If the user sets
IFLA_GTP_CREATE_SOCKETS attribute, then GTP module takes care
of creating UDP sockets by itself. Sockets are created with the
commonly known UDP ports used for GTP protocol (GTP0_PORT and
GTP1U_PORT). In this case we don't have to provide encap_destroy
because no extra deinitialization is needed, everything is covered
by udp_tunnel_sock_release.

Note: GTP instance created with only this change applied, does
not handle GTP Echo Requests. This is implemented in the following
patch.

ASoC: Intel: avs: Inter process communication
Implement the IPC between Intel audio firmware and kernel driver. The
IPC allows transmission of requests, handling of responses as well as
unsolicited (i.e. firmware-generated) notifications.

A subscription mechanism is added to enable different parts of the
driver to register for specific notifications.

The part of the DSP boot process that involves sending ROM message
requires an extra step - must be followed by unstall operation of
MAIN_CORE. All other types of messages do not require such specific
handling, so separate set of functions is provided for sending these.

during its initialization, without being limited to topology loading

Allows users to first check available resources e.g. number of PCMs
supported by HDAudio codec before allocating the number of DAPM
widgets needed. This prevents superfluous objects from being created or

239bbb2fe9 drm/i915/gt: Remove GEN12_SFC_DONE_MAX from register defs header
We shouldn't really be keeping track of how many SFC_DONE registers
our platforms can have, but rather how many SFC hardware units there can
be (each SFC unit will have one corresponding SFC_DONE register).  So
drop the stray GEN12_SFC_DONE_MAX definition we had in the register
definition file and replace it with an I915_MAX_SFC that follows the
pattern we use for other hardware units.  Note that our hardware has a
2:1:1 ratio of VD:VE:SFC, and as far as we know that pattern should
carry forward to future platforms, so we'll define it as #VCS/2.

e23b2f54db dt-bindings: mmc: sunxi: add Allwinner F1c100s compatible
The Allwinner F1C100 series contains two MMC controller blocks. From
comparing the data sheets, they seem to be compatible with the one used
in the Allwinner A20: the register layout is the same, and they use the
same separate sample and output clocks design.
The only difference is the missing reset line in the A20 version, but
both the binding and the Linux driver make this optional, so it's still
a fit.

Add the new SoC specific name and require it to be paired with the A20
fallback name, as this is all the driver needs to care about.

Eventually support for NFSv2 in the Linux NFS server is to be
deprecated and then removed.

However, NFSv2 is the "always supported" version that is available
as soon as CONFIG_NFSD is set.  Before NFSv2 support can be removed,
we need to choose a different "always supported" version.

This patch removes CONFIG_NFSD_V3 so that NFSv3 is always supported,
as NFSv2 is today. When NFSv2 support is removed, NFSv3 will become
the only "always supported" NFS version.

The defconfigs still need to be updated to remove CONFIG_NFSD_V3=y.

Displaying "PREEMPT" on kernel headers when CONFIG_PREEMPT_DYNAMIC=y
can be misleading for anybody involved in remote debugging because it
is then not guaranteed that there is an actual preemption behaviour. It
depends on default Kconfig or boot defined choices.

Therefore, tell about PREEMPT_DYNAMIC on static kernel headers and leave
