If a transaction error happens in vhci_recv_ret_submit(), event
handler closes connection and changes port status to kick hub_event.
Then hub tries to flush the endpoint URBs, but that causes infinite
loop between usb_hub_flush_endpoint() and vhci_urb_dequeue() because
"vhci_priv" in vhci_urb_dequeue() was already released by
vhci_recv_ret_submit() before a transmission error occurred. Thus,
vhci_urb_dequeue() terminates early and usb_hub_flush_endpoint()
continuously calls vhci_urb_dequeue().
The root cause of this issue is that vhci_recv_ret_submit()
terminates early without giving back URB when transaction error
occurs in vhci_recv_ret_submit(). That causes the error URB to still
be linked at endpoint list without “vhci_priv".
So, in the case of transaction error in vhci_recv_ret_submit(),
unlink URB from the endpoint, insert proper error code in
urb->status and give back URB.

When vhci uses SG and receives data whose size is smaller than SG
buffer size, it tries to receive more data even if it acutally
receives all the data from the server. If then, it erroneously adds
error event and triggers connection shutdown.
vhci-hcd should check if it received all the data even if there are
more SG entries left. So, check if it receivces all the data from
the server in for_each_sg() loop.

When disconnecting a USB hub that has some child device(s) connected to it
(such as a USB mouse), then the stack tries to clear halt and
reset device(s) which are _already_ physically disconnected.
The issue has been reproduced with:
CPU: IMX6D5EYM10AD or MCIMX6D5EYM10AE.
SW: U-Boot 2019.07 and kernel 4.19.40.
CPU: HP Proliant Microserver Gen8.
SW: Linux version 4.2.3-300.fc23.x86_64
In this situation there will be error bit for MMF active yet the
CERR equals EHCI_TUNE_CERR + halt. Existing implementation
interprets this as a stall [1] (chapter 8.4.5).
The possible conditions when the MMF will be active + halt
can be found from [2] (Table 4-13).
Fix for the issue is to check whether MMF is active and PID Code is
IN before checking for the stall. If these conditions are true then
it is not a stall.
What happens after the fix is that when disconnecting a hub with
attached device(s) the situation is not interpret as a stall.

spin_unlock_irqrestore() might be called with stale flags after
reading port status, possibly restoring interrupts to a incorrect
state.
If a usb2 port just finished resuming while the port status is read
the spin lock will be temporary released and re-acquired in a separate
function. The flags parameter is passed as value instead of a pointer,
not updating flags properly before the final spin_unlock_irqrestore()
is called.

xhci driver claims it needs XHCI_TRUST_TX_LENGTH quirk for both
Broadcom/Cavium and a Renesas xHC controllers.
The quirk was inteded for handling false "success" complete event for
transfers that had data left untransferred.
These transfers should complete with "short packet" events instead.
In these two new cases the false "success" completion is reported
after a "short packet" if the TD consists of several TRBs.
xHCI specs 4.10.1.1.2 say remaining TRBs should report "short packet"
as well after the first short packet in a TD, but this issue seems so
common it doesn't make sense to add the quirk for all vendors.
Turn these events into short packets automatically instead.
This gets rid of the "The WARN Successful completion on short TX for
slot 1 ep 1: needs XHCI_TRUST_TX_LENGTH quirk" warning in many cases.

A race in xhci USB3 remote wake handling may force device back to suspend
after it initiated resume siganaling, causing a missed resume event or warm
reset of device.
When a USB3 link completes resume signaling and goes to enabled (UO)
state a interrupt is issued and the interrupt handler will clear the
bus_state->port_remote_wakeup resume flag, allowing bus suspend.
If the USB3 roothub thread just finished reading port status before
the interrupt, finding ports still in suspended (U3) state, but hasn't
yet started suspending the hub, then the xhci interrupt handler will clear
the flag that prevented roothub suspend and allow bus to suspend, forcing
all port links back to suspended (U3) state.
Example case:
usb_runtime_suspend() # because all ports still show suspended U3
usb_suspend_both()
hub_suspend(); # successful as hub->wakeup_bits not set yet
==> INTERRUPT
xhci_irq()
handle_port_status()
clear bus_state->port_remote_wakeup
usb_wakeup_notification()
sets hub->wakeup_bits;
kick_hub_wq()
<== END INTERRUPT
hcd_bus_suspend()
xhci_bus_suspend() # success as port_remote_wakeup bits cleared
Fix this by increasing roothub usage count during port resume to prevent
roothub autosuspend, and by making sure bus_state->port_remote_wakeup
flag is only cleared after resume completion is visible, i.e.
after xhci roothub returned U0 or other non-U3 link state link on a
get port status request.

HC died; cleaning up
The order between hcd_uses_dma() and hcd->localmem_pool is now
arranged as in hcd_buffer_alloc() and hcd_buffer_free(), with the
test for hcd->localmem_pool placed first.
As an alternative, one might consider adjusting hcd_uses_dma() with
static inline bool hcd_uses_dma(struct usb_hcd *hcd)

- return IS_ENABLED(CONFIG_HAS_DMA) && (hcd->driver->flags & HCD_DMA);

Gadget driver should always use config_ep_by_speed() to initialize
usb_ep struct according to usb device's operating speed. Otherwise,
usb_ep struct may be wrong if usb devcie's operating speed is changed.
The key point in this patch is that we want to make sure the desc pointer
in usb_ep struct will be set to NULL when gadget is disconnected.
This will force it to call config_ep_by_speed() to correctly initialize
usb_ep struct based on the new operating speed when gadget is
re-connected later.

The problem arises because our read() function grabs a lock of the
circular buffer, finds something of interest, then invokes copy_to_user()
straight from the buffer, which in turn takes mm->mmap_sem. In the same
time, the callback mon_bin_vma_fault() is invoked under mm->mmap_sem.
It attempts to take the fetch lock and deadlocks.
This patch does away with protecting of our page list with any
semaphores, and instead relies on the kernel not close the device
while mmap is active in a process.
In addition, we prohibit re-sizing of a buffer while mmap is active.
This way, when (now unlocked) fault is processed, it works with the
page that is intended to be mapped-in, and not some other random page.
Note that this may have an ABI impact, but hopefully no legitimate
program is this wrong.

Add kcov_remote_start()/kcov_remote_stop() annotations to the
hub_event() function, which is responsible for processing events on USB
buses, in particular events that happen during USB device enumeration.
Since hub_event() is run in a global background kernel thread (see
Documentation/dev-tools/kcov.rst for details), each USB bus gets a
unique global handle from the USB subsystem kcov handle range. As the
result kcov can now be used to collect coverage from events that happen
on a particular USB bus.

This is mostly update of the usual drivers: aacraid, ufs, zfcp,
NCR5380, lpfc, qla2xxx, smartpqi, hisi_sas, target, mpt3sas, pm80xx
plus a whole load of minor updates and fixes. The two major core
changes are Al Viro's reworking of sg's handling of copy to/from user,
Ming Lei's removal of the host busy counter to avoid contention in the
multiqueue case and Damien Le Moal's fixing of residual tracking
across error handling.

As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need support
for time64_t.
In completely unrelated work, I spent time on cleaning up parts of this
file in the past, moving things out into drivers instead.
After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the rest
of it and move it all into drivers.
This series incorporates some of Al's work and many patches of my own,
but in the end stops short of actually removing the last part, which is
the scsi ioctl handlers. I have patches for those as well, but they need
more testing or possibly a rewrite.

The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.

XUSB phy needs to be enabled before un-powergating the power partitions.
However in the current sequence, it happens opposite. Correct the phy
enable and powergating partition sequence to avoid any boot hangs.
