For control IO, qeth currently tracks the index of the buffer that it
expects to complete the next IO on each qeth_channel. If the channel
presents an IRQ while this buffer has not yet completed, no completion
processing for _any_ completed buffer takes place.
So if the 'next buffer' is skipped for any sort of reason* (eg. when it
is released due to error conditions, before the IO is started), the
buffer obviously won't switch to PROCESSED until it is eventually
allocated for a _different_ IO and completes.
Until this happens, all completion processing on that channel stalls
and pending requests possibly time out.
As a fix, remove the whole 'next buffer' logic and simply process any
IO buffer right when it completes. A channel will never have more than
one IO pending, so there's no risk of processing out-of-sequence.
*Note: currently just one location in the code really handles this problem,
by advancing the 'next' index manually.

Commit e7bfb3fdbde3 ("mtd: Stop updating erase_info->state and calling
mtd_erase_callback()") removed the einfo->state field and the
MTD_ERASE_XXX macros. At the same time, the generic NAND layer was added
and made sure to update the erase info state.
It did not result in a build failure after merging the nand/for-4.17
branch in mtd/next because the generic NAND layer is not selected yet.
Let's fix that before a config option starts selecting MTD_NAND_CORE.

The new axp288 extcon driver has no dependency on USB itself but
calls the usb role switch helper functions. This causes a link error
when USB_COMMON is disabled, as that subdirectory never gets entered:

There are multiple ways of fixing this, I chose to 'select USB_COMMON',
since that is how we solved the same problem for other helpers like
USB_LED_TRIG or PHY drivers.

Currently hcd.c is the only consumer of the usb_phy_roothub logic. This

However, future consumers might not know about struct device.

If the generic PHY support is disabled the stub of devm_of_phy_get_by_index
returns ENOSYS. This corner case isn't handled properly by
usb_phy_roothub_add_phy and at least breaks USB support on Raspberry Pi
(bcm2835_defconfig):
dwc2 20980000.usb: dwc2_hcd_init() FAILED, returning -38
dwc2: probe of 20980000.usb failed with error -38
Let usb_phy_roothub_alloc() return in case CONFIG_GENERIC_PHY is
disabled to fix this issue (compilers might even be smart enough to
optimize away most of the code within usb_phy_roothub_alloc and
usb_phy_roothub_add_phy if CONFIG_GENERIC_PHY is disabled). All
existing usb_phy_roothub_* functions are already NULL-safe, so no
special handling is required there.

If the USB controller can wake up the system (which is the case for
example with the Mediatek USB3 IP) then we must not call phy_exit during
suspend to ensure that the USB controller doesn't have to re-enumerate
the devices during resume.
However, if the USB controller cannot wake up the system (which is the
case for example on various TI platforms using a dwc3 controller) then
we must call phy_exit during suspend. Otherwise the PHY driver keeps the
clocks enabled, which prevents the system from reaching the lowest power
levels in the suspend state.
Solve this by introducing two new functions in the PHY wrapper which are
dedicated to the suspend and resume handling.
If the controller can wake up the system the new usb_phy_roothub_suspend
function will simply call usb_phy_roothub_power_off. However, if wake up
is not supported by the controller it will also call
usb_phy_roothub_exit.
The also new usb_phy_roothub_resume function takes care of calling
usb_phy_roothub_init (if the controller can't wake up the system) in
addition to usb_phy_roothub_power_on.

Before this patch usb_phy_roothub_init served two purposes (from a
caller's point of view - like hcd.c):
- parsing the PHYs and allocating the list entries
- calling phy_init on each list entry
While this worked so far it has one disadvantage: if we need to call
phy_init for each PHY instance then the existing code cannot be re-used.
Solve this by splitting off usb_phy_roothub_alloc which only parses the
PHYs and allocates the list entries.
usb_phy_roothub_init then gets a struct usb_phy_roothub and only calls
phy_init on each PHY instance (along with the corresponding cleanup if
that failed somewhere).
This is a preparation step for adding proper suspend support for some
hardware that requires phy_exit to be called during suspend and phy_init
to be called during resume.

usb_phy_roothub_exit() should return the error code from the phy_exit()
call if exiting the PHY failed.
However, since a wrong variable is used usb_phy_roothub_exit() currently
always returns 0, even if one of the phy_exit calls returned an error.
Clang also reports this bug:
kernel/drivers/usb/core/phy.c:114:8: warning: explicitly assigning value of
variable of type 'int' to itself [-Wself-assign] error, forbidden
warning: phy.c:114
Fix this by assigning the error code from phy_exit() to the "ret"
variable to propagate the error correctly.

This compination is quite hard to create because CONFIG_TRACING gets selected

The build failure is caused by conditionally compiling trace.c depending on

On chromebooks we depend on wakeup count to identify the wakeup source.
But currently USB devices do not increment the wakeup count when they
trigger the remote wake. This patch addresses the same.
Resume condition is reported differently on USB 2.0 and USB 3.0 devices.
On USB 2.0 devices, a wake capable device, if wake enabled, drives
resume signal to indicate a remote wake (USB 2.0 spec section 7.1.7.7).
The upstream facing port then sets C_PORT_SUSPEND bit and reports a
port change event (USB 2.0 spec section 11.24.2.7.2.3). Thus if a port
has resumed before driving the resume signal from the host and
C_PORT_SUSPEND is set, then the device attached to the given port might
be the reason for the last system wakeup. Increment the wakeup count for
the same.
On USB 3.0 devices, a function may signal that it wants to exit from device
suspend by sending a Function Wake Device Notification to the host (USB3.0
spec section 8.5.6.4) Thus on receiving the Function Wake, increment the
wakeup count.

Some of the mport_dma_req structure members were initialized late
inside the do_dma_request() function, just before submitting the
request to the dma engine. But we have some error branches before
that. In case of such an error, the code would return on the error
path and trigger the calling of dma_req_free() with a req structure
which is not completely initialized. This causes a NULL pointer

This patch fixes these error branches by making sure that all

rio_dma_transfer() immediately after the request structure gets
allocated.

Currently the pcie_print_link_status() will print PCIe bandwidth and link
width information but does not mention it is pertaining to the PCIe. Since
this and related functions are used exclusively by networking drivers today
users may get confused into thinking that it's the NIC bandwidth that is
being talked about. Insert a "PCIe" into the messages.

On Armada 7K/8K we need to explicitly enable the register clock. This
clock is optional because not all the SoCs using this IP need it but at
least for Armada 7K/8K it is actually mandatory.
The change was done at xhci-plat level and not at a xhci-mvebu.c because,
it is expected that other SoC would have this kind of constraint.
The binding documentation is updating accordingly.

The Dell Inspiron 5775 is a Raven Ridge. The Enable Slot command timed
out when a USB device gets plugged:
[ 212.156326] xhci_hcd 0000:03:00.3: Error while assigning device slot ID
[ 212.156340] xhci_hcd 0000:03:00.3: Max number of devices this xHCI host supports is 64.
[ 212.156348] usb usb2-port3: couldn't allocate usb_device
AMD suggests that a delay before xHC suspends can fix the issue.
I can confirm it fixes the issue, so use the suspend delay quirk for
Raven Ridge's xHC.

MAP_SYNC is a nop for device-dax. Allow MAP_SYNC to succeed on device-dax
to eliminate special casing between device-dax and fs-dax as to when the
flag can be specified. Device-dax users already implicitly assume that they do
not need to call fsync(), and this enables them to explicitly check for this

In some firmware images, the length of BNX_DIR_TYPE_PKG_LOG nvram type
could be greater than the fixed buffer length of 4096 bytes allocated by
the driver. This was causing HWRM_NVM_READ to copy more data to the buffer
than the allocated size, causing general protection fault.
Fix the issue by allocating the exact buffer length returned by
HWRM_NVM_FIND_DIR_ENTRY, instead of 4096. Move the kzalloc() call
into the bnxt_get_pkgver() function.

When sending control commands, virtio net sets up several buffers for
DMA. The buffers are all part of the net device which means it's
actually allocated by kvmalloc so it's in theory (on extreme memory
pressure) possible to get a vmalloc'ed buffer which on some platforms
means we can't DMA there.
Fix up by moving the DMA buffers into a separate structure.

When longer interface names are used, the action names exposed in
/proc/interrupts and /proc/irq/* maybe truncated. For example, when
using the predictable name algorithm in systemd on a HiSilicon D05,
I see:
ubuntu@d05-3:~$ grep enahisic2i0-tx /proc/interrupts | sed 's/.* //'
enahisic2i0-tx0
enahisic2i0-tx1

Increase the max ring name length to allow for an interface name

vmxnet3_get_hdr_len() is used to calculate the header length which in
turn is used to calculate the gso_size for skb. When rxvlan offload is
disabled, vlan tag is present in the header and the function references
ip header from sizeof(ethhdr) and leads to incorrect pointer reference.
This patch fixes this issue by taking sizeof(vlan_ethhdr) into account
if vlan tag is present and correctly references the ip hdr.
