Change the fprobe exit handler to use ftrace_regs structure instead of
pt_regs. This also introduce HAVE_FTRACE_REGS_HAVING_PT_REGS which
means the ftrace_regs is including the pt_regs so that ftrace_regs
can provide pt_regs without memory allocation.
Fprobe introduces a new dependency with that.

instead of CONFIG_DYNAMIC_FTRACE_WITH_REGS, then we can enable fprobe

Use ftrace_regs instead of fgraph_ret_regs for tracing return value
on function_graph tracer because of simplifying the callback interface.
The CONFIG_HAVE_FUNCTION_GRAPH_RETVAL is also replaced by

Pass ftrace_regs to the fgraph_ops::entryfunc(). If ftrace_regs is not
available, it passes a NULL instead. User callback function can access
some registers (including return address) via this ftrace_regs.
Note that the ftrace_regs can be NULL when the arch does NOT define:
HAVE_DYNAMIC_FTRACE_WITH_ARGS or HAVE_DYNAMIC_FTRACE_WITH_REGS.
More specifically, if HAVE_DYNAMIC_FTRACE_WITH_REGS is defined but
not the HAVE_DYNAMIC_FTRACE_WITH_ARGS, and the ftrace ops used to
register the function callback does not set FTRACE_OPS_FL_SAVE_REGS.
In this case, ftrace_regs can be NULL in user callback.

The logic for invoking __DO_TRACE_CALL was extracted to a static inline
function called __rust_do_trace_##name so that Rust can call it
directly. This logic does not include the static branch, to avoid a
function call when the tracepoint is disabled.
Since the C code needs to perform the same logic after checking the
static key, this logic is currently duplicated. Thus, remove this
duplication by having C call the static inline function too.

The function dyn_event_release() uses argv_split() which must be freed via
argv_free(). It contains several error paths that do a goto out to call
argv_free() for cleanup. This makes the code complex and error prone.
Create a new __free() directive __free(argv_free) that will call
argv_free() for data allocated with argv_split(), and use it in the
dyn_event_release() function.

While at it, used u32_encode_bits which made the code easier to

The use of cpu_to_le32 was wrong and thus removed.

To make it easier for X1P4 and X1E to share a common device tree base,
extend the existing latter's GPUCC bindings and reuse them on the
former platform.
While not in the same file, it only makes sense to introduce the new

It is not helpful to error out on some SDCA function types, we
might as well report the correct name and let the driver core
simply not bind a driver to those functions for which the code
lacks support. Also given no functions currently have support,
it seems odd to select some as unsupported.

SDCA only supports 3-bits for the function address, but the ACPI value
is 64-bits. Update the code that parses this to do a bounds check
and error out on invalid addresses. Currently, an invalid address
would truncate to the bottom 3-bits when used and thus use a likely
incorrect address. With the bounds check, it is also now safe to
shrink the size of the adr member of sdca_function_desc to a u8 and
rearrange the struct members to pack better with the new size of adr.

Several of the SDCA files don't include all the headers they use
locally. These are included by the point of use through other
headers, so it is not currently causing any issues. However, files
should directly include things they directly use, so add the
missing header includes.

patterns. Add support for this in ib_core so that we can get rid
of duplicate codes in each driver.
A new last_port_state is added in ib_port_cache to cache the port
state of the last link status events dispatching. The original
port_state in ib_port_cache is not used here because it will be
updated when ib_dispatch_event() is called, which means it may
be changed between two link status events, and may lead to a loss
of event dispatching.
Some drivers currently have some private stuff in their link status
events handler in addition to event dispatching, and cannot be
perfectly integrated into the ib_core handling process. For these
drivers, add a new ops report_port_event() so that they can keep
their current processing.
Finally, events of LAG devices are not supported yet in this patch
as currently there is no way to obtain ibdev from upper netdev in
ib_core. This can be a TODO work after the core have more support
for LAG.

Commit 265b07df758a ("clk: Provide managed helper to get and enable bulk
clocks") added devm_clk_bulk_get_all_enable() function, but missed to
return the number of clocks stored in the clk_bulk_data table referenced
by the clks argument. Without knowing the number, it's not possible to
iterate these clocks when needed, hence the argument is useless and
could have been simply removed.
A new helper devm_clk_bulk_get_all_enabled() has been introduced, which
is consistent with devm_clk_bulk_get_all() in terms of the returned
value.
Drop the obsolete function since all users switched to the new helper.

In the cited commit, when changing from switchdev to legacy mode,
uplink representor's netdev is kept, and its profile is replaced with
nic profile, so netdev is detached from old profile, then attach to
new profile.
During profile change, the hardware resources allocated by the old
profile will be cleaned up. However, the cleanup is relying on the
related kernel modules. And they may need to flush themselves first,
which is triggered by netdev events, for example, NETDEV_UNREGISTER.
However, netdev is kept, or netdev_register is called after the
cleanup, which may cause troubles because the resources are still
referred by kernel modules.
The same process applies to all the caes when uplink is leaving
switchdev mode, including devlink eswitch mode set legacy, driver
unload and devlink reload. For the first one, it can be blocked and
returns failure to users, whenever possible. But it's hard for the
others. Besides, the attachment to nic profile is unnecessary as the
netdev will be unregistered anyway for such cases.
So in this patch, the original behavior is kept only for devlink
eswitch set mode legacy. For the others, moves netdev unregistration
before the profile change.

Rename SKB_DROP_REASON_VXLAN_NO_REMOTE and give it a more generic name,

blk_mq_pci_map_queues and blk_mq_virtio_map_queues will create a CPU to
hardware queue mapping based on affinity information. These two function
share common code and only differ on how the affinity information is
retrieved. Also, those functions are located in the block subsystem
where it doesn't really fit in. They are virtio and pci subsystem
specific.
Thus introduce provide a generic mapping function which uses the
irq_get_affinity callback from bus_type.

BIP_CHECK_GUARD/REFTAG are conversion of existing semantics, while
BIP_CHECK_APPTAG is a new flag. The driver can now just rely on block
layer flags, and doesn't need to know the integrity source. Submitter
of PI decides which tags to check. This would also give us a unified
