Add the ZTE (Vodafone) K3765-Z to the whitelist. This requires the
previous patch to make the whitelist with forced interface 4 generic
or the device fails to initialise. After applying this patch and
loading the Option driver without usb-modeswitch's bind all
interfaces trick, a wwan0 net interface and /dev/cdc-wdm0 device
file were created. Using Bjorn Mork's perl connection script a
connection was made to a mobile network using QMI and the network
interface's IPv4 address was configured OK.

Change the forced interface 4 whitelist to use the generic shared
binder instead of the Gobi specific one. Certain ZTE devices
(K3520-Z & K3765-Z) don't work with the Gobi version, but function
quite happily with the generic. This has been tested with the following
devices:
K3520-Z
K3565-Z
K3765-Z
K4505-Z
It hasn't been tested with the ZTE MF820D, which is the only other
device that uses this whitelist at present. Although Bjorn doesn't
expect any problems, any testing with that device would be appreciated.

Pull a dm fix from Alasdair G Kergon:
"A fix to the thin provisioning userspace interface."
* tag 'dm-3.4-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm:
dm thin: fix table output when pool target disables discard passdown internally
|
|
When the thin pool target clears the discard_passdown parameter
internally, it incorrectly changes the table line reported to userspace.
This breaks dumb string comparisons on these table lines in generic
userspace device-mapper library code and leads to tables being reloaded
repeatedly when nothing is actually meant to be changing.
This patch corrects this by no longer changing the table line when
discard passdown was disabled.
We can still tell when discard passdown is overridden by looking for the
message "Discard unsupported by data device (sdX): Disabling discard passdown."
This automatic detection is also moved from the 'load' to the 'resume'
so that it is re-evaluated should the properties of underlying devices
change.

As iwlwifi use fat skbs, it should not pull too much data in skb->head,
and particularly no tcp data payload, or splice() is slower, and TCP
coalescing is disabled. Copying payload to userland also involves at
least two copies (part from header, part from fragment)
Each layer will pull its header from the fragment as needed.
(on 64bit arches, skb_tailroom(skb) at this point is 192 bytes)
With this patch applied, I have a major reduction of collapsed/pruned
TCP packets, a nice increase of TCPRcvCoalesce counter, and overall
better Internet User experience.
Small packets are still using a fragless skb, so that page can be reused
by the driver.

Commit 1cc0c998fdf2 ("ACPI: Fix D3hot v D3cold confusion") introduced a
bug in __acpi_bus_set_power() and changed the behavior of
acpi_pci_set_power_state() in such a way that it generally doesn't work
as expected if PCI_D3hot is passed to it as the second argument.
First off, if ACPI_STATE_D3 (equal to ACPI_STATE_D3_COLD) is passed to
__acpi_bus_set_power() and the explicit_set flag is set for the D3cold
state, the function will try to execute AML method called "_PS4", which
doesn't exist.
Fix this by adding a check to ensure that the name of the AML method
to execute for transitions to ACPI_STATE_D3_COLD is correct in
__acpi_bus_set_power(). Also make sure that the explicit_set flag
for ACPI_STATE_D3_COLD will be set if _PS3 is present and modify
acpi_power_transition() to avoid accessing power resources for
ACPI_STATE_D3_COLD, because they don't exist.
Second, if PCI_D3hot is passed to acpi_pci_set_power_state() as the
target state, the function will request a transition to
ACPI_STATE_D3_HOT instead of ACPI_STATE_D3. However,
ACPI_STATE_D3_HOT is now only marked as supported if the _PR3 AML
method is defined for the given device, which is rare. This causes
problems to happen on systems where devices were successfully put
into ACPI D3 by pci_set_power_state(PCI_D3hot) which doesn't work
now. In particular, some unused graphics adapters are not turned
off as a result.
To fix this issue restore the old behavior of
acpi_pci_set_power_state(), which is to request a transition to
ACPI_STATE_D3 (equal to ACPI_STATE_D3_COLD) if either PCI_D3hot or
PCI_D3cold is passed to it as the argument.
This approach is not ideal, because generally power should not
be removed from devices if PCI_D3hot is the target power state,
but since this behavior is relied on, we have no choice but to
restore it at the moment and spend more time on designing a
better solution in the future.

Pull two more target-core updates from Nicholas Bellinger:
"The first patch addresses a SPC-2 reservations RELEASE bug in a
special (iscsi specific) multi-ISID setup case that was allowing the
same initiator to be able to incorrect release it's own reservation on

caught by Bernhard Kohl.
The second patch is to address a bug with FILEIO backends where the
incorrect number of blocks for READ_CAPACITY was being reported after
an underlying device-mapper block_device size change. This patch uses
now i_size_read() in fd_get_blocks() for FILEIO backends with an
underlying block_device, instead of trying to determine this value at
setup time during fd_create_virtdevice(). (hch CC'ed)

Change the TX ring scheme such that the number of rings for untagged packets
and for tagged packets (per each of the vlan priorities) is the same, unlike
the current situation where for tagged traffic there's one ring per priority
and for untagged rings as the number of core.
Queue selection is done as follows:
If the mqprio qdisc is operates on the interface, such that the core networking
code invoked the device setup_tc ndo callback, a mapping of skb->priority =>
queue set is forced - for both, tagged and untagged traffic.
Else, the egress map skb->priority => User priority is used for tagged traffic, and
all untagged traffic is sent through tx rings of UP 0.
The patch follows the convergence of discussing that issue with John Fastabend

This patch fixes a bug in the handling of FILEIO w/ underlying block_device
resize operations where the original fd_dev->fd_dev_size was incorrectly being
used in fd_get_blocks() for READ_CAPACITY response payloads.
This patch avoids using fd_dev->fd_dev_size for FILEIO devices with
an underlying block_device, and instead changes fd_get_blocks() to
get the sector count directly from i_size_read() as recommended by hch.

According to the comment, errata 23 says that the memory we allocate
can't cross a 64KiB boundary. In case of jumbo frames we allocate
complete pages which can never cross the 64KiB boundary because
PAGE_SIZE should be a multiple of 64KiB so we stop either before the
boundary or start after it but never cross it. Furthermore the check
seems bogus because it looks at skb->data which is not seen by the HW
at all because we only pass the DMA address of the page we allocated. So
I *think* the workaround is not required here.

__napi_schedule might raise softirq but nothing
causes do_softirq to trigger, so it does not in fact
run. As a result,
the error message "NOHZ: local_softirq_pending 08"
sometimes occurs during boot of a KVM guest when the network service is
started and we are oom:
...
Bringing up loopback interface: [ OK ]
Bringing up interface eth0:
Determining IP information for eth0...NOHZ: local_softirq_pending 08
done.
[ OK ]
...
Further, receive queue processing might get delayed
indefinitely until some interrupt triggers:
virtio_net expected napi to be run immediately.
One way to cause do_softirq to be executed is by
invoking local_bh_enable(). As __napi_schedule is
normally called from bh or irq context, this
seems to make sense: disable bh before __napi_schedule
and enable afterwards.
In fact it's a very complicated way of calling do_softirq(),
and works since this function is only used when we are not
in interrupt context. It's not hot at all, in any ideal scenario.

Use del_timer_sync to remove timer before mddev_suspend finishes.
We don't want a timer going off after an mddev_suspend is called. This is
especially true with device-mapper, since it can call the destructor function
immediately following a suspend. This results in the removal (kfree) of the
structures upon which the timer depends - resulting in a very ugly panic.
Therefore, we add a del_timer_sync to mddev_suspend to prevent this.

addressing and so need to be updated carefully.
However raid10_resize isn't updating it at all!
To update it correctly, we need to make sure it is a proper
multiple of the chunksize taking various details of the layout
in to account.
This calculation is currently done in setup_conf. So split it
out from there and call it from raid10_resize as well.
Then set conf->dev_sectors properly.
