On a disconnect, dwc2 will kill all remaining urbs from qh list.
urbs are given back to hcd with -ETIMEDOUT status.
Some usb device driver, like mass storage, will unlink all urbs
using usb_hcd_unlink_urb when receiving a negative status different
from -ECONNRESET.
The following flow will then happen:
dwc2_hcd_disconnect()
-> dwc2_kill_all_urbs() try to kill first pending urb.
-> dwc2_host_complete(-ETIMEDOUT)
-> usb_hcd_giveback_urb(-ETIMEDOUT)
-> sg_complete()
-> usb_unlink_urb()
-> usb_put_dev(urb->dev)
-> dwc2_kill_all_urbs() try to kill next pending urb.
-> dwc2_host_complete(-ETIMEDOUT)
-> usb_hcd_giveback_urb(-ETIMEDOUT)
-> NULL pointer dereferencing because urb->dev has been freed for all
urbs of this device.
The root cause of this NULL pointer is to call call usb_unlink_urb()
while we are killing all urbs. To avoid this return urb with
-ECONNRESET status
This issue usually happens while removing mass storage device during
transfer.

Some high speed mass storage devices fail to enumerate with following
error:
Cannot enable port %i. Maybe the USB cable is bad?
This happens only when the device is plugged while the controller
is in hibernation state. After exiting hibernation, the controller
detects the device as a low speed device and fail to enumerate it.
Problem occurs only if HPRT0.PWR bit is programmed in a too short
delay after exiting hibernation. Dumping hprt register in
_dwc2_hcd_resume() directly after dwc2_exit_hibernation() shows that
HPRT0.LNSTS (D+/D- level) becomes valid approximately 2ms after
exiting hibernation.
Since dwc2_exit_hibernation() is called from atomic context, move the
delay out of this function.
Delay value is experimental and not mentioned in Synopsys
documentation. To be on the safe side 3ms delay is used.

The ->init_size() hook was introduced to let NAND controller drivers
support NAND devices that could not be described in the nand_ids table.
Since then, the core has added support for extended-id parsing and
full-id description, thus allowing to describe pretty much all existing
NANDs.
Moreover, this hook is not used by any mainline driver, and should not be
used by new drivers, because detecting the NAND chip is not something
controller specific.

The sfc driver internally uses a time format based on 32-bit (unsigned)
seconds and 32-bit nanoseconds. This means it will overflow in 2106,
but the value we pass into it is a signed 32-bit tv_sec that already
overflows in 2038 to a negative value.
This patch changes the logic to use the lower 32 bits of the timespec64
tv_sec in efx_ptp_ns_to_s_ns, which will have the correct value beyond the overflow.
While this does not change any of the register values, it lets us
keep using the driver after we deprecate the use of the timespec type
in the kernel.
In the efx_ptp_process_times function, the change to use timespec64
is similar, in that the tv_sec portion is ignored anyway and we only
care about the nanosecond portion that remains unchanged.

The pps_event_time uses two 'timespec' structures internally, which
suffer from the y2038 problem. The uses of this structure are
fairly self-contained in the pps code, so this replaces them all at
once.
Unfortunately, this includes the sfc ethernet driver aside from the
pps subsystem, so we change that one as well. Both touch the
same data structure, and there probably is no good way to split
the patch into smaller units.

There is only one user of the hardpps function in the kernel, so
it makes sense to atomically change it over to using 64-bit
timestamps for y2038 safety. In the hardpps implementation,
we also need to change the pps_normtime structure, which is
similar to struct timespec and also requires a 64-bit
seconds portion.
This introduces two temporary variables in pps_kc_event() to
do the conversion, they will be removed again in the next step,
which seemed preferable to having a larger patch changing it
all at the same time.

In specific, any resource used with flat/heapless (0x00000000-0xfffff000)
General State Heap (GSH) or Instruction State Heap (ISH) must be in a

Objects must have EXEC_OBJECT_SUPPORTS_48B_ADDRESS flag to indicate if
they can be allocated above the 32-bit address range. To limit the
