590e853444 hwmon: (lm85) Drop generic detection
Generic detection leads to too many false positives, so drop it. FWIW
sensors-detect does not have such generic detection. If the user wants
to force the driver to bind to a not yet supported chip, he/she can
still do so using sysfs attribute new_device.

c0214f9894 hwmon: (ina2xx) Cast to s16 on shunt and current regs
All devices supported by ina2xx are bidirectional and report the
measured shunt voltage and power values as a signed 16 bit, but the
current driver implementation caches all registers as u16, leading
to an incorrect sign extension when reporting to userspace in
ina2xx_get_value().

This patch fixes the problem by casting the signed registers to s16.
Tested on an INA219.

883854c545 dlm: keep listening connection alive with sctp mode
The connection struct with nodeid 0 is the listening socket,
not a connection to another node.  The sctp resend function
was not checking that the nodeid was valid (non-zero), so it
would mistakenly get and resend on the listening connection
when nodeid was zero.

b4f75aea55 ALSA: hda - verify pin:converter connection on unsol event for HSW and VLV
This patch will verify the pin's coverter selection for an active stream
when an unsol event reports this pin becomes available again after a display
mode change or hot-plug event.

For Haswell+ and Valleyview: display mode change or hot-plug can change the
transcoder:port connection and make all the involved audio pins share the 1st
converter. So the stream using 1st convertor will flow to multiple pins
but active streams using other converters will fail. This workaround
is to assure the pin selects the right conveter and an assigned converter is
not shared by other unused pins.

5d01b7684b mmc: simplify SDHCI Kconfig dependencies
We have a number of front-end drivers for SDHCI_PLTFM, some of them
use 'select MMC_SDHCI_PLTFM', others use 'depends on'. This is
inconsistent and confusing, and in one case has also led to a
build error because of incomplete dependencies:

warning: (MMC_SDHCI_PXAV3 && MMC_SDHCI_PXAV2 && MMC_SDHCI_BCM_KONA) selects MMC_SDHCI_PLTFM which has unmet direct dependencies (MMC && MMC_SDHCI)
drivers/built-in.o: In function `sdhci_sirf_resume':
:(.text+0xaaacb4): undefined reference to `sdhci_resume_host'
drivers/built-in.o: In function `sdhci_sirf_suspend':

:(.text+0xaaaf44): undefined reference to `sdhci_add_host'
:(.text+0xaaaf50): undefined reference to `sdhci_remove_host'

This changes Kconfig to use 'depends on MMC_SDHCI_PLTFM' for all these
cases, to fix the build error and make the logic more logical.

60a549fcda mmc: omap: don't select TPS65010
The MMC host driver should not select the pmic driver, since that
may have other dependencies, notably i2c in this case. It's not
clear what the exact requirement of the driver is, but to preserve
the behavior, this patch changes the 'select' into 'depends on',
meaning you now have to turn on TPS65010 explicitly and then
MMC_OMAP.

Found during randconfig build testing.

ed1761d7d8 mmc: sdhci-msm: Fix fallout from sdhci refactoring
The sdhci core was refactored recently and some of those
refactorings required changes in every sdhci platform driver.
Those updates happened around the same time as when the msm
driver was merged so the refactorings missed the msm driver.
Hook in the basic library functions so that we can boot apq8074
dragonboards again instead of crashing when we try to jump to
NULL function pointers.

699c659b49 powerpc: Avoid circular dependency with zImage.%
The rule to create the final images uses a zImage.% pattern.
Unfortunately, this also matches the names of the zImage.*.lds linker
scripts, which appear as a dependency of the final images. This somehow
worked when $(srctree) used to be an absolute path, but now the pattern
matches too much. List only the images from $(image-y) as the target of
the rule, to avoid the circular dependency.

c2338f2dc7 lock_parent: don't step on stale ->d_parent of all-but-freed one
Dentry that had been through (or into) __dentry_kill() might be seen
by shrink_dentry_list(); that's normal, it'll be taken off the shrink
list and freed if __dentry_kill() has already finished.  The problem
is, its ->d_parent might be pointing to already freed dentry, so
lock_parent() needs to be careful.

We need to check that dentry hasn't already gone into __dentry_kill()
*and* grab rcu_read_lock() before dropping ->d_lock - the latter makes
sure that whatever we see in ->d_parent after dropping ->d_lock it
won't be freed until we drop rcu_read_lock().

4251c2a670 Most of this is cleaning up various driver sysfs permissions so we can
re-add the perm check (we unified the module param and sysfs checks, but
 the module ones were stronger so we weakened them temporarily).
 
 Param parsing gets documented, and also "--" now forces args to be
 handed to init (and ignored by the kernel).
 
 Module NX/RO protections get tightened: we now set them before calling
 parse_args().
 
 Cheers,
 Rusty.

Commit 1d8faf48c7 (net/core: Add VF link state control) added VF link state
control to the netlink VF nested structure, but failed to add a proper entry
for the new structure into the VF policy table.  Add the missing entry so
the table and the actual data copied into the netlink nested struct are in
sync.

6e765a009a net_sched: drr: warn when qdisc is not work conserving
The DRR scheduler requires that items on the active list are work
conserving, i.e. do not hold on to skbs for throttling purposes, etc.
Attaching e.g. tbf renders DRR useless because all other classes on the
active list are delayed as well.

So, warn users that this configuration won't work as expected; we
already do this in couple of other qdiscs, see e.g.

commit b00355db3f
('pkt_sched: sch_hfsc: sch_htb: Add non-work-conserving warning handler')

The 'const' change is needed to avoid compiler warning ("discards 'const'
qualifier from pointer target type").

tested with:
drr_hier() {
        parent=$1
        classes=$2
        for i in  $(seq 1 $classes); do
                classid=$parent$(printf %x $i)
                tc class add dev eth0 parent $parent classid $classid drr
		tc qdisc add dev eth0 parent $classid tbf rate 64kbit burst 256kbit limit 64kbit
        done
}
tc qdisc add dev eth0 root handle 1: drr
drr_hier 1: 32
tc filter add dev eth0 protocol all pref 1 parent 1: handle 1 flow hash keys dst perturb 1 divisor 32

net: Checksum offload changes - Part IV

I am working on overhauling RX checksum offload. Goals of this effort
are:

- Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY
- Preserve CHECKSUM_COMPLETE through encapsulation layers
- Don't do skb_checksum more than once per packet
- Unify GRO and non-GRO csum verification as much as possible
- Unify the checksum functions (checksum_init)
- Simply code

What is in this fourth patch set:

- Preserve CHECKSUM_COMPLETE instead of changing it to
  CHECKSUM_UNNECESSARY. This allows correct reuse in validating multiple
  csums in a packet.
- When SW needs to compute the packet checksum, save it as
  CHECKSUM_COMPLETE. Also mark that checksum was compute by SW.
- Add skb_gro_postpull_rcsum to udp and vxlan to make GRO work with
  CHECKSUM_COMPLETE.

v2: Removed patch setting skb_encapsulation when validating checksum
    in tcp_gro_receive

Please review carefully and test if possible, mucking with basic
checksum functions is always a little precarious :-)

7e3cead517 net: Save software checksum complete
In skb_checksum complete, if we need to compute the checksum for the
packet (via skb_checksum) save the result as CHECKSUM_COMPLETE.
Subsequent checksum verification can use this.

Also, added csum_complete_sw flag to distinguish between software and
hardware generated checksum complete, we should always be able to trust
the software computation.

5d0c2b95bc net: Preserve CHECKSUM_COMPLETE at validation
Currently when the first checksum in a packet is validated using
CHECKSUM_COMPLETE, ip_summed is overwritten to be CHECKSUM_UNNECESSARY
so that any subsequent checksums in the packet are not correctly
validated.

This patch adds csum_valid flag in sk_buff and uses that to indicate
validated checksum instead of setting CHECKSUM_UNNECESSARY. The bit
is set accordingly in the skb_checksum_validate_* functions. The flag
is checked in skb_checksum_complete, so that validation is communicated
between checksum_init and checksum_complete sequence in TCP and UDP.
