this only works when the given directory is below the current directory.
`realpath --relative-to=.` will return a relative path in all cases.

- Add MAINTAINERS entry for zcrx, mostly so that netdev gets
automatically CC'ed by default on any changes there too.
- Fix for the SQPOLL busy vs work time accounting.
It was using getrusage(), which was both broken from a thread point
of view (we only care about the SQPOLL thread itself), and vastly
overkill as only the systime was used. On top of that, also be a bit
smarter in when it's queried. It used excessive CPU before this
change. Marked for stable as well.

As of commit aac6db75a9 ("vfio/pci: Use unmap_mapping_range()"),
vm_pgoff may no longer guaranteed to hold the PFN for VM_PFNMAP
regions. Using vma->vm_pgoff to derive the HPA here may therefore
produce incorrect mappings.
Instead, I/O mappings for such regions can be established on-demand
during g-stage page faults, making the upfront ioremap in this path
is unnecessary.

The RFCOMM driver confuses the local and remote modem control signals,
which specifically means that the reported DTR and RTS state will
instead reflect the remote end (i.e. DSR and CTS).
This issue dates back to the original driver (and a follow-on update)
merged in 2002, which resulted in a non-standard implementation of
TIOCMSET that allowed controlling also the TS07.10 IC and DV signals by
mapping them to the RI and DCD input flags, while TIOCMGET failed to
return the actual state of DTR and RTS.
Note that the bogus control of input signals in tiocmset() is just
dead code as those flags will have been masked out by the tty layer
since 2003.

Periodic advertising enabled flag cannot be tracked by the enabled
flag since advertising and periodic advertising each can be
enabled/disabled separately from one another causing the states to be
inconsistent when for example an advertising set is disabled its
enabled flag is set to false which is then used for periodic which has
not being disabled.

A different structure is stored in drvdata for the drivers which used
that duplicate function, but h4_recv_buf() assumes drvdata is always an
hci_uart structure.
Consequently, alignment and padding are now randomly corrupted for
btmtkuart, btnxpuart, and bpa10x in h4_recv_buf(), causing erratic
breakage.
Fix this by making the hci_uart structure the explicit argument to
h4_recv_buf(). Every caller already has a reference to hci_uart, and
already obtains the hci_hdev reference through it, so this actually
eliminates a redundant pointer indirection for all existing callers.

In the current btintel_pcie driver implementation, when an interrupt is
received, the driver checks for the alive cause before the TX/RX cause.
Handling the alive cause involves resetting the TX/RX queue indices.
This flow works correctly when the causes are mutually exclusive.
However, if both cause bits are set simultaneously, the alive cause
resets the queue indices, resulting in an event packet drop and a
command timeout. To fix this issue, the driver is modified to handle all
other causes before checking for the alive cause.

This reverts commit c9d84da18d. It
replaces in L2CAP calls to msecs_to_jiffies() to secs_to_jiffies()
and updates the constants accordingly. But the constants are also
used in LCAP Configure Request and L2CAP Configure Response which
expect values in milliseconds.
This may prevent correct usage of L2CAP channel.
To fix it, keep those constants in milliseconds and so revert this
change.

There is a BUG: KASAN: stack-out-of-bounds in set_mesh_sync due to
memcpy from badly declared on-stack flexible array.
Another crash is in set_mesh_complete() due to double list_del via
mgmt_pending_valid + mgmt_pending_remove.
Use DEFINE_FLEX to declare the flexible array right, and don't memcpy
outside bounds.
As mgmt_pending_valid removes the cmd from list, use mgmt_pending_free,
and also report status on error.

This fixes the state tracking of advertisement set/instance 0x00 which
is considered a legacy instance and is not tracked individually by
adv_instances list, previously it was assumed that hci_dev itself would
track it via HCI_LE_ADV but that is a global state not specifc to
instance 0x00, so to fix it a new flag is introduced that only tracks the
state of instance 0x00.

This patch adds logic to handle power management control when the
Bluetooth function is closed during the SDIO reset sequence.
Specifically, if BT is closed before reset, the driver enables the
SDIO function and sets driver pmctrl. After reset, if BT remains
closed, the driver sets firmware pmctrl and disables the SDIO function.
These changes ensure proper power management and device state consistency
across the reset flow.

hci_cmd_sync_dequeue_once() does lookup and then cancel
the entry under two separate lock sections. Meanwhile,
hci_cmd_sync_work() can also delete the same entry,
leading to double list_del() and "UAF".
Fix this by holding cmd_sync_work_lock across both
lookup and cancel, so that the entry cannot be removed
concurrently.

Commit c1e18c17bd ("s390/pci: add zpci_set_irq()/zpci_clear_irq()"),
introduced the zpci_set_irq() and zpci_clear_irq(), to be used while
resetting a zPCI device.
Commit da995d538d ("s390/pci: implement reset_slot for hotplug
slot"), mentions zpci_clear_irq() being called in the path for
zpci_hot_reset_device(). But that is not the case anymore and these
functions are not called outside of this file. Instead
zpci_hot_reset_device() relies on zpci_disable_device() also clearing
the IRQs, but misses to reset the zdev->irqs_registered flag.
However after a CLP disable/enable reset, the device's IRQ are
unregistered, but the flag zdev->irq_registered does not get cleared. It
creates an inconsistent state and so arch_restore_msi_irqs() doesn't
correctly restore the device's IRQ. This becomes a problem when a PCI
driver tries to restore the state of the device through
pci_restore_state(). Restore IRQ unconditionally for the device and remove
the irq_registered flag as its redundant.
