The third marked for stable suppresses some serious log spam from unnecessary

xhci: Bug fixes, now with more tags!
Hi Greg,
Here's five bug fixes for 3.12.

for example ath9k_htc with stalled firmware, kernel will
crash on ring_doorbell_for_active_rings.
This patch check if pointer exist before it is used.

Xhci controllers with hci_version > 0.96 gives spurious success
events on short packet completion. During webcam capture the
"ERROR Transfer event TRB DMA ptr not part of current TD" was observed.
The same application works fine with synopsis controllers hci_version 0.96.
The same issue is seen with Intel Pantherpoint xhci controller. So enabling
this quirk in xhci_gen_setup if controller verion is greater than 0.96.
For xhci-pci move the quirk to much generic place xhci_gen_setup.
Note from Sarah:
The xHCI 1.0 spec changed how hardware handles short packets. The HW
will notify SW of the TRB where the short packet occurred, and it will
also give a successful status for the last TRB in a TD (the one with the
IOC flag set). On the second successful status, that warning will be
triggered in the driver.
Software is now supposed to not assume the TD is not completed until it
gets that last successful status. That means we have a slight race
condition, although it should have little practical impact. This patch
papers over that issue.
It's on my long-term to-do list to fix this race condition, but it is a
much more involved patch that will probably be too big for stable. This
patch is needed for stable to avoid serious log spam.
This patch should be backported to kernels as old as 3.0, that
contain the commit ad808333d8 "Intel xhci:
Ignore spurious successful event."
The patch will have to be modified for kernels older than 3.2, since
that kernel added the xhci_gen_setup function for xhci platform devices.
The correct conflict resolution for kernels older than 3.2 is to set
XHCI_SPURIOUS_SUCCESS in xhci_pci_quirks for all xHCI 1.0 hosts.

drivers/usb/host/xhci.c:3901:12: warning: 'xhci_change_max_exit_latency' defined but not used [-Wunused-function]
These functions are not always used, and since they're marked static
they will produce build warnings:
- xhci_msix_sync_irqs is only used with CONFIG_PCI.
- xhci_change_max_exit_latency is a little more complicated with
dependencies on CONFIG_PM and CONFIG_PM_RUNTIME.
Instead of building a bigger maze of ifdefs in this code, I've just
marked both with __maybe_unused.

When the host controller fails to respond to an Enable Slot command, and
the host fails to respond to the register write to abort the command
ring, the xHCI driver will assume the host is dead, and call
usb_hc_died().
The USB device's slot_id is still set to zero, and the pointer stored at
xhci->devs[0] will always be NULL. The call to xhci_check_args in
xhci_free_dev should have caught the NULL virt_dev pointer.
However, xhci_free_dev is designed to free the xhci_virt_device
structures, even if the host is dead, so that we don't leak kernel
memory. xhci_free_dev checks the return value from the generic
xhci_check_args function. If the return value is -ENODEV, it carries on
trying to free the virtual device.
The issue is that xhci_check_args looks at the host controller state
before it looks at the xhci_virt_device pointer. It will return -ENIVAL
because the host is dead, and xhci_free_dev will ignore the return
value, and happily dereference the NULL xhci_virt_device pointer.
The fix is to make sure that xhci_check_args checks the xhci_virt_device
pointer before it checks the host state.
See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1203453 for
further details. This patch doesn't solve the underlying issue, but
will ensure we don't see any more NULL pointer dereferences because of
the issue.
This patch should be backported to kernels as old as 3.1, that
contain the commit 7bd89b4017 "xhci: Don't
submit commands or URBs to halted hosts."

The hub driver was recently changed to use "global" suspend for system
suspend transitions on non-SuperSpeed buses. This means that we don't
suspend devices individually by setting the suspend feature on the
upstream hub port; instead devices all go into suspend automatically
when the root hub stops transmitting packets. The idea was to save
time and to avoid certain kinds of wakeup races.
Now it turns out that many hubs are buggy; they don't relay wakeup
requests from a downstream port to their upstream port if the
downstream port's suspend feature is not set (depending on the speed
of the downstream port, whether or not the hub is enabled for remote
wakeup, and possibly other factors).
We can't have hubs dropping wakeup requests. Therefore this patch
goes partway back to the old policy: It sets the suspend feature for a
port if the device attached to that port or any of its descendants is
enabled for wakeup. People will still be able to benefit from the
time savings if they don't care about wakeup and leave it disabled on
all their devices.
In order to accomplish this, the patch adds a new field to the usb_hub
structure: wakeup_enabled_descendants is a count of how many devices
below a suspended hub are enabled for remote wakeup. A corresponding
new subroutine determines the number of wakeup-enabled devices at or
below an arbitrary suspended USB device.
This should be applied to the 3.10 stable kernel.
