In the current code, devres_release_all() only gets called if the device
has a bus and has been probed.

This leads to issues when using bus-less or driver-less devices where
the device might never get freed if a managed resource holds a reference
to the device. This is happening in the DRM framework for example.

We should thus call devres_release_all() in the device_del() function to
make sure that the device-managed actions are properly executed when the
device is unregistered, even if it has neither a bus nor a driver.

This is effectively the same change than commit 2f8d16a9 ("devres:
release resources on device_del()") that got reverted by commit
a525a3dd ("driver core: free devres in device_release") over
memory leaks concerns.

This patch effectively combines the two commits mentioned above to
release the resources both on device_del() and device_release() and get
the best of both worlds.

Platform devices show some inconsistencies with how devm resources are
released when the device has been probed and when it hasn't.

In particular, we can register device-managed actions no matter if the
device has be bound to a driver or not, but devres_release_all() will
only be called if it was bound to a driver or if there's no reference
held to it anymore.

If it wasn't bound to a driver and we still have a reference,
devres_release_all() will never get called. This is surprising
considering that if the driver isn't bound but doesn't have any
reference to it anymore, that function will get called, and if it was
bound to a driver but still has references, that function will get
called as well.

Even if that case is fairly unusual, it can easily lead to memory leaks.

The plan is, with the next patch, to make it consistent and enforce that
devres_release_all() is called no matter what situation we're in. For
now, it just tests for the current behaviour and skips over the
inconsistencies.

The root devices show some odd behaviours compared to regular "bus" devices
that have been probed through the usual mechanism, so let's create kunit
tests to exercise those paths and odd cases.

It's not clear whether root devices are even allowed to use device
managed resources, but the fact that it works in some cases but not
others like shown in that test suite shouldn't happen either way: we
want to make it consistent and documented.

These tests will (after the following patches) ensure that consistency
and effectively document that it's allowed.

If it ever turns out to be a bad idea, we can always roll back and
modify the tests then.

The update of the kernfs directory node child count was also protected

Booting the kernel with "maxcpus=1" is a common technique for CPU
partitioning and isolation. It delays the CPU bringup process until
when the bootup scripts are ready to bring CPUs online by writing 1 to
/sys/device/system/cpu/cpu<X>/online. However, it was found that not
all the CPUs were online after bootup. The collection of offline CPUs
are different after every reboot.

Further investigation reveals that some "online" write operations
fail with an -EBUSY error. This error is returned when CPU hotplug is
temporiarly disabled when cpu_hotplug_disable() is called.

During bootup, the main caller of cpu_hotplug_disable() is
pci_call_probe() for PCI device initialization. By measuring the times
spent with cpu_hotplug_disabled set in a typical 2-socket server, most
of them last less than 10ms.  However, there are a few that can last
hundreds of ms. Note that the cpu_hotplug_disabled period of different
devices can overlap leading to longer cpu_hotplug_disabled hold time.

Since the CPU hotplug disable condition is transient and it is not
that easy to modify all the existing bootup scripts to handle this
condition, the kernel can help by retrying the online operation when
an -EBUSY error is returned. This patch retries the online operation
in cpu_subsys_online() when an -EBUSY error is returned for up to 5
times after an exponentially increasing delay that can last a total of
at least 620ms of waiting time by calling msleep().

With this patch in place, booting up the patched kernel with "maxcpus=1"
does not leave any CPU in an offline state in 10 reboot attempts.

* "It must fix only one thing" was dropped, as that is almost always a

  Furthermore, this is already indirectly covered by the "Separate your

Group some variables based on their sizes to reduce hole and avoid padding.
On x86_64, this shrinks the size of 'struct kobject' from 256 to 244 bytes.

This structure is often included in some other structures. So these other
structures will also benefit from this 8 bytes saving.

This is especially nice for structure like 'cma_kobject' or 'class_dir'
that are now 256 bytes long. When they are kzalloc()'ed, 256 bytes are
allocated, instead of 512.

Pull probe fixes from Masami Hiramatsu:

 - probe-events: add NULL check for some BTF API calls which can return
   error code and NULL.

 - ftrace selftests: check fprobe and kprobe event correctly. This fixes
   a miss condition of the test command.

 - kprobes: do not allow probing functions that start with "__cfi_" or
   "__pfx_" since those are auto generated for kernel CFI and not
   executed.

Pull locking fix from Borislav Petkov:

 - Fix a rtmutex race condition resulting from sharing of the sort key
   between the lock waiters and the PI chain tree (->pi_waiters) of a
   task by giving each tree their own sort key

Pull x86 fixes from Borislav Petkov:

 - AMD's automatic IBRS doesn't enable cross-thread branch target
   injection protection (STIBP) for user processes. Enable STIBP on such
   systems.

 - Do not delete (but put the ref instead) of AMD MCE error thresholding
   sysfs kobjects when destroying them in order not to delete the kernfs
   pointer prematurely

 - Restore annotation in ret_from_fork_asm() in order to fix kthread
   stack unwinding from being marked as unreliable and thus breaking
   livepatching

Pull irq fixes from Borislav Petkov:

 - Work around an erratum on GIC700, where a race between a CPU handling
   a wake-up interrupt, a change of affinity, and another CPU going to
   sleep can result in a lack of wake-up event on the next interrupt

 - Fix the locking required on a VPE for GICv4

 - Enable Rockchip 3588001 erratum workaround for RK3588S

 - Fix the irq-bcm6345-l1 assumtions of the boot CPU always be the first
   CPU in the system

  fs/nls: make load_nls() take a const parameter

Pull tracing fixes from Steven Rostedt:

 - Fix to /sys/kernel/tracing/per_cpu/cpu*/stats read and entries.

   If a resize shrinks the buffer it clears the read count to notify
   readers that they need to reset. But the read count is also used for
   accounting and this causes the numbers to be off. Instead, create a
   separate variable to use to notify readers to reset.

 - Fix the ref counts of the "soft disable" mode. The wrong value was
   used for testing if soft disable mode should be enabled or disable,
   but instead, just change the logic to do the enable and disable in
   place when the SOFT_MODE is set or cleared.

 - Several kernel-doc fixes

 - Removal of unused external declarations
