Pull PCMCIA update from Dominik Brodowski:
"A few PCMCIA fixes and cleanups are available in the PCMCIA tree.
Most of them are trivial and self-explanatory. Of particular note are
the last three patches which add an important hardware quirk for

sockets), fix resource leaks in yenta_socket enable/disable call
paths, and fix a regression caused by patch 1c6c9b1d9d25 since v4.0.
Alan stated he is OK with me pushing this patch upstream. Once it
works out well in your tree, I will push it to stable for 4.0/4.1 as

Pull gpio updates from Linus Walleij:
"This is the big bulk of GPIO changes queued for the v4.2 kernel
series:
- a big set of cleanups to the aged sysfs interface from Johan
Hovold. To get these in, v4.1-rc3 was merged into the tree as the
first patch in that series had to go into stable. This makes the
locking much more fine-grained (get rid of the "big GPIO lock(s)"
and store states in the GPIO descriptors.
- rename gpiod_[g|s]et_array() to gpiod_[g|s]et_array_value() to
avoid confusions.
- New drivers for:
* NXP LPC18xx (currently LPC1850)
* NetLogic XLP
* Broadcom STB SoC's
* Axis ETRAXFS
* Zynq Ultrascale+ (subdriver)
- ACPI:
* make it possible to retrieve GpioInt resources from a GPIO
device using acpi_dev_gpio_irq_get()
* merge some dependent I2C changes exploiting this.
* support the ARM X-Gene GPIO standby driver.
- make it possible for the generic GPIO driver to read back the value
set registers to reflect current status.
- loads of OMAP IRQ handling fixes.
- incremental improvements to Kona, max732x, OMAP, MXC, RCAR,
PCA953x, STP-XWAY, PCF857x, Crystalcove, TB10x.
- janitorial (constification, checkpatch cleanups)"

Newer versions of mount parse the lazytime feature and pass it to the

commit 6d3da24141 ("KVM: s390: deliver floating interrupts in order

We don't clear the bitmap of pending floating interrupts
and interrupt parameters. This could result in stale interrupts
even after a reset. Let's fix this by clearing the pending bitmap
and the parameters for service and machine check interrupts.

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.
Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

Below case causes mii bus probe failed:
ifconfig eth0 down -> suspend/resume with Mega/fax mix off -> ifconfig eth0 up
In i.MX6SX/i.MX7D chip, Mega/fast mix off feature is supported that means most of
SOC power will be off including ENET MAC for power saving. Once ENET MAC power
off, all initialized MAC registers reset to default, so in the case, it must
init MAC prior to mii bus probe.

While IEEE and CEE use the same structure to store apps, the selector
and priority fields for both are different. Only the priority field is
explained, add documentation explaining how the selector field differs
for both.
cgdcbxd code shows an example of how selector fields differ.

This particular BUG_ON condition was checking for attr set err in the
COMMIT phase, which isn't expected (it's a driver bug if PREPARE phase is
OK but COMMIT fails). But BUG_ON() is too strong for this case, so change
to WARN(). BUG_ON() would be warranted if the system was corrupted beyond
repair, but this is not the case here.

switchdev; add VLAN support for port's bridge_getlink
One more missing piece of the puzzle. Add vlan dump support to switchdev
port's bridge_getlink. iproute2 "bridge vlan show" cmd already knows how
to show the vlans installed on the bridge and the device , but (until now)
no one implemented the port vlan part of the netlink PF_BRIDGE:RTM_GETLINK
msg. Before this patch, "bridge vlan show":
$ bridge -c vlan show
port vlan ids
sw1p1 30-34 << bridge side vlans
57
sw1p1 << device side vlans (missing)
sw1p2 57
sw1p2

(When the port is bridged, the output repeats the vlan list for the vlans
on the bridge side of the port and the vlans on the device side of the
port. The listing above show no vlans for the device side even though they
are installed).
After this patch:
$ bridge -c vlan show

I re-used ndo_dflt_bridge_getlink to add vlan fill call-back func.
switchdev support adds an obj dump for VLAN objects, using the same
call-back scheme as FDB dump. Support included for both compressed and
un-compressed vlan dumps.

Remove handling of tx_ring in prb_setup_retire_blk_timer
for TPACKET_V3 because init_prb_bdqc is called only for zero tx_ring
and thus prb_setup_retire_blk_timer for zero tx_ring only.
And also in functon init_prb_bdqc there is no usage of tx_ring.
Thus removing tx_ring from init_prb_bdqc.

This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.
However the references to it continue to spread as boiler plate text
from one Kconfig file into the next. We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.
No code is changed in this commit, just Kconfig help text.

Apart from small cleanups, this series provides support for the dwmac

The mac settings like RGMII/RMII, speeds etc are done in the so called
"General Register Files", contain numerous other settings as well and
always seem to change between Rockchip SoCs. Therefore abstract the
register accesses into a per-soc ops struct to make this reusable on
other Rockchip SoCs.

The first iteration of the dwmac-rk support did access an intermediate
clock directly below the pll selector. This was removed in a subsequent
revision, but the clock and one invocation remained. This results in
the driver trying to set the rate of a non-existent clock when the soc
and not some external source provides the phy clock for RMII phys.
So set the rate of the correct clock and remove the remaining now
completely unused definition.

In a first version the driver did want to do some gpio wiggling, which

The reason:
MPC5121 FEC requires 4-byte alignment for TX data buffer and calls
tx_skb_align_workaround() for copying sk_buff with not aligned .data to a new
sk_buff with aligned one. But tx_skb_align_workaround() uses
skb_copy_from_linear_data() which doesn't work for non-linear sk_buff:
a new sk_buff has non-zero nr_frags and zero .data_len.
So improve the condition of calling tx_skb_align_workaround() and use
skb_linearize() in it.
