dev_coredumpm
The dev_coredumpv() and dev_coredumpm() could not be used in atomic
context, because they call kvasprintf_const() and kstrdup() with
GFP_KERNEL parameter. The process is shown below:
dev_coredumpv(.., gfp_t gfp)
dev_coredumpm(.., gfp_t gfp)
dev_set_name
kobject_set_name_vargs
kvasprintf_const(GFP_KERNEL, ...); //may sleep
kstrdup(s, GFP_KERNEL); //may sleep
This patch removes gfp_t parameter of dev_coredumpv() and dev_coredumpm()
and changes the gfp_t parameter of kzalloc() in dev_coredumpm() to
GFP_KERNEL in order to show they could not be used in atomic context.

Pull signature checking selftest from David Howells:
"The signature checking code, as used by module signing, kexec, etc.,
is non-FIPS compliant as there is no selftest.
For a kernel to be FIPS-compliant, signature checking would have to be
tested before being used, and the box would need to panic if it's not
available (probably reasonable as simply disabling signature checking
would prevent you from loading any driver modules).
Deal with this by adding a minimal test.
This is split into two patches: the first moves load_certificate_list()
to the same place as the X.509 code to make it more accessible
internally; the second adds a selftest"

The BPF core/verifier is hard-coded to permit mixing bpf2bpf and tail
calls for only x86-64. Change the logic to instead rely on a new weak
function 'bool bpf_jit_supports_subprog_tailcalls(void)', which a capable
JIT backend can override.
Update the x86-64 eBPF JIT to reflect this.

Panel orientation property should be set before drm_dev_register().
Some drm driver calls drm_dev_register() in .bind(). However, most
panels sets orientation property relatively late, mostly in .get_modes()
callback, since this is when they are able to get the connector and
binds the orientation property to it, though the value should be known
when the panel is probed.
In drm_bridge_connector_init(), if a bridge is a panel bridge, use it to
set the connector's panel orientation property.

Panels usually call drm_connector_set_panel_orientation(), which is
later than drm/kms driver calling drm_dev_register(). This leads to a
WARN().
The orientation property is known earlier. For example, some panels
parse the property through device tree during probe.
Add an API to return the property from panel to drm/kms driver, so the
drivers are able to call drm_connector_set_orientation_from_panel() before
drm_dev_register().

There are some drivers that can use the Type C mux API, but don't have
to. Introduce CONFIG guards for the mux functions so that drivers can
include the header file and not run into compilation errors on systems
which don't have CONFIG_TYPEC enabled. When CONFIG_TYPEC is not enabled,
the Type C mux functions will be stub versions of the original calls.

Calls to `bpf_loop` are replaced with direct loops to avoid
indirection. E.g. the following:
bpf_loop(10, foo, NULL, 0);
Is replaced by equivalent of the following:
for (int i = 0; i < 10; ++i)
foo(i, NULL);
This transformation could be applied when:
- callback is known and does not change during program execution;
- flags passed to `bpf_loop` are always zero.
Inlining logic works as follows:
- During execution simulation function `update_loop_inline_state`
tracks the following information for each `bpf_loop` call
instruction:
- is callback known and constant?
- are flags constant and zero?
- Function `optimize_bpf_loop` increases stack depth for functions
where `bpf_loop` calls can be inlined and invokes `inline_bpf_loop`
to apply the inlining. The additional stack space is used to spill
registers R6, R7 and R8. These registers are used as loop counter,
loop maximal bound and callback context parameter;
Measurements using `benchs/run_bench_bpf_loop.sh` inside QEMU / KVM on
i7-4710HQ CPU show a drop in latency from 14 ns/op to 2 ns/op.

This commit places any task that has ever blocked within its current
RCU Tasks Trace read-side critical section on a per-CPU list within the
rcu_tasks_percpu structure. Tasks are removed from this list when they
exit by the exit_tasks_rcu_finish_trace() function. The purpose of this
commit is to provide the information needed to eliminate the current
scan of the full task list.
This commit offsets the INT_MIN value for ->trc_reader_nesting with the
new nesting level in order to avoid queueing tasks that are exiting
their read-side critical sections.

This commit gets rid of the task_struct structure's ->trc_reader_checked
field, making it instead be a bit within the task_struct structure's
existing ->trc_reader_special.b.need_qs field. This commit also
atomically loads, stores, and checks the resulting combination of the
reader-checked and need-quiescent state flags. This will in turn allow
significant simplification of the rcu_tasks_trace_postgp() function
as well as elimination of the trc_n_readers_need_end counter in later
commits. These changes will in turn simplify later elimination of the
RCU Tasks Trace scan of the task list, which will make RCU Tasks Trace
grace periods less CPU-intensive.

It is currently up to the caller to handle stale return values from
get_state_synchronize_rcu(). If poll_state_synchronize_rcu() returned
true once, a grace period has elapsed, regardless of the fact that counter
wrap might cause some future poll_state_synchronize_rcu() invocation to
return false. For example, the caller might store a separate flag that
indicates whether some previous call to poll_state_synchronize_rcu()
determined that the relevant grace period had already ended.
This approach works, but it requires extra storage and is easy to get
wrong. This commit therefore introduces a get_completed_synchronize_rcu()
that returns a cookie that causes poll_state_synchronize_rcu() to always
return true. This already-completed cookie can be stored in place of the
cookie that previously caused poll_state_synchronize_rcu() to return true.
It can also be used to flag a given structure as not having been exposed
to readers, and thus not requiring a grace period to elapse.
This commit is in preparation for polled expedited grace periods.

Add some optional callbacks for link add/remove so that

sufficient to just create the link in start_ap etc., but
it turns out that's not so simple, since there are quite
a few callbacks that can be called: if they're erroneously
without start_ap, things might crash.
Thus it might be easier for drivers to allocate all the
necessary data structures immediately, to not have to
worry about it in each callback, since cfg80211 checks
that the link ID is valid (has been added.)

Note that a station entry must be created representing an

For authentication, we need the BSS, the link_id and the AP
MLD address to create the link and station, (for now) the
driver assigns a link address and sends the frame, the MLD
address needs to be the address of the interface.
For association, pass the list of BSSes that were selected
for the MLO connection, along with extra per-STA profile
elements, the AP MLD address and the link ID on which the
association request should be sent.
Note that for now we don't have a proper way to pass the link
address(es) and so the driver/mac80211 will select one, but
depending on how that selection works it means that assoc w/o
auth data still being around (mac80211 implementation detail)
the association won't necessarily work - so this will need to
be extended in the future to sort out the link addressing.

In order to support multi-link operation with multiple links,
start adding some APIs. The notable addition here is to have
the link ID in a new nl80211 attribute, that will be used to
differentiate the links in many nl80211 operations.
So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID
attribute (as well as the NL80211_ATTR_MLO_LINKS attribute)
and plugs it through the system in some places, checking the
validity etc. along with other infrastructure needed for it.
For now, I've decided to include only the over-the-air link
ID in the API. I know we discussed that we eventually need to
have to have other ways of identifying a link, but for local
AP mode and auth/assoc commands as well as set_key etc. we'll
use the OTA ID.
Also included in this patch is some refactoring of the data
structures in struct wireless_dev, splitting for the first
time the data into type dependent pieces, to make reasoning
about these things easier.
