Now that VirtualBox is able to run as a host on arm64 (e.g. the Apple M3
processors) we can enable VBOXSF_FS (and in turn VBOXGUEST) for this
architecture. Tested with various runs of bonnie++ and dbench on an Apple
MacBook Pro with the latest Virtualbox 7.1.4 r165100 installed.

The kafs filesystem limits the maximum length of a cell to 256 bytes, but a
problem occurs if someone actually does that: kafs tries to create a
directory under /proc/net/afs/ with the name of the cell, but that fails
with a warning:
WARNING: CPU: 0 PID: 9 at fs/proc/generic.c:405
because procfs limits the maximum filename length to 255.
However, the DNS limits the maximum lookup length and, by extension, the
maximum cell name, to 255 less two (length count and trailing NUL).
Fix this by limiting the maximum acceptable cellname length to 253. This
also allows us to be sure we can create the "/afs/.<cell>/" mountpoint too.
Further, split the YFS VL record cell name maximum to be the 256 allowed by
the protocol and ignore the record retrieved by YFSVL.GetCellName if it
exceeds 253.

Macbook 5,1 with MCP79 lost its backlight control since the recent
change for supporting GSP-RM; it rewrote the whole nv50 backlight

Commit 79d2e1919a ("staging: gpib: fix Makefiles") uses the corresponding
config symbols to let Makefiles include the driver sources appropriately in
the kernel build.
Unfortunately, the Makefile in the tnt4882 directory refers to the
non-existing config GPIB_TNT4882. The actual config name for this driver is
GPIB_NI_PCI_ISA, as can be observed in the gpib Makefile.
Probably, this is caused by the subtle differences between the config
names, directory names and file names in ./drivers/staging/gpib/, where
often config names and directory names are identical or at least close in
naming, but in this case, it is not.
Change the reference in the tnt4882 Makefile from the non-existing config
GPIB_TNT4882 to the existing config GPIB_NI_PCI_ISA.

kernel BUG at lib/list_debug.c:62!
Kernel panic - not syncing: Oops - BUG: Fatal exception
This happens because pps_device_destruct() frees the pps_device with the
embedded cdev immediately after calling cdev_del(), but, as the comment
above cdev_del() notes, fops for previously opened cdevs are still
callable even after cdev_del() returns. I think this bug has always
been there: I can't explain why it suddenly started happening every time
I reboot this particular board.
In commit d953e0e837 ("pps: Fix a use-after free bug when
unregistering a source."), George Spelvin suggested removing the
embedded cdev. That seems like the simplest way to fix this, so I've
implemented his suggestion, using __register_chrdev() with pps_idr
becoming the source of truth for which minor corresponds to which
device.
But now that pps_idr defines userspace visibility instead of cdev_add(),
we need to be sure the pps->dev refcount can't reach zero while
userspace can still find it again. So, the idr_remove() call moves to
pps_unregister_cdev(), and pps_idr now holds a reference to pps->dev.

ACTLR value is unique for each SMR (Stream matching register) and stored

for NETDEV_REGISTER [1] wasn't fired on a simplest QEMU setup
like e1000 + x86_64_defconfig + CONFIG_DEBUG_NET_SMALL_RTNL.

rtnl_lock_killable() is used only in register_netdev()
and will be converted to per-netns RTNL.
Let's unexport it and add the corresponding helper.

In cases where the work done is less than the budget, `fbnic_poll` is
returning 0. This affects the tracing of `napi_poll`. Following is a
snippet of before and after result from `napi_poll` tracepoint. Instead,
returning the work done improves the manual tracing.

ESN context must be synced between software and hardware for both RX
and TX. As the call to xfrm_dev_state_advance_esn() is added for TX,
this patch add the missing logic for TX. So the update is also checked
on every packet sent, to see if need to trigger ESN update worker.

Previously xfrm_dev_state_advance_esn() was added for RX only. But
it's possible that ESN context also need to be synced to hardware for
TX, so call it for outbound in this patch.
