"This includes a couple of fixes needed after recent changes, two ACPI
driver fixes (fan and "Processor Aggregator"), an update of the ACPI
device properties handling code and a new MAINTAINERS entry for ACPI
on ARM64.
Specifics:
- Fix an unused function warning that started to appear after recent
changes in the ACPI EC driver (Eric Biggers).
- Fix the KERN_CONT usage in acpi_os_vprintf() that has become
(particularly) annoying recently (Joe Perches).
- Fix the fan status checking in the ACPI fan driver to avoid
returning incorrect error codes sometimes (Srinivas Pandruvada).
- Fix the ACPI Processor Aggregator driver (PAD) to always let the
special processor_aggregator driver from Xen take over when running
as Xen dom0 (Juergen Gross).
- Update the handling of reference device properties in ACPI by
allowing empty rows ("holes") to appear in reference property lists
(Mika Westerberg).
- Add a new MAINTAINERS entry for ACPI on ARM64 (Lorenzo Pieralisi)"

Pull more power management updates from Rafael Wysocki:
"This includes a couple of fixes for cpufreq regressions introduced in
4.8, a rework of the intel_pstate algorithm used on Atom processors
(that took some time to test) plus a fix and a couple of cleanups in
that driver, a CPPC cpufreq driver fix, and a some devfreq fixes and
cleanups (core and exynos-nocp).
Specifics:
- Fix two cpufreq regressions causing undesirable changes in behavior
to appear (one in the core and one in the conservative governor)
introduced during the 4.8 cycle (Aaro Koskinen, Rafael Wysocki).
- Fix the way the intel_pstate driver accesses MSRs related to the
hardware-managed P-states (HWP) feature during the initialization
which currently is unsafe and may cause the processor to generate a
general protection fault (Srinivas Pandruvada).
- Rework the intel_pstate's P-state selection algorithm used on Atom
processors to avoid known problems with the current one and to make
the computation more straightforward, which also happens to improve
performance in multiple benchmarks a bit (Rafael Wysocki).
- Improve two comments in the intel_pstate driver (Rafael Wysocki).
- Fix the desired performance computation in the CPPC cpufreq driver
(Hoan Tran).
- Fix the devfreq core to avoid printing misleading error messages in
some cases (Tobias Jakobi).
- Fix the error code path in devfreq_add_device() to use proper
locking around list modifications (Axel Lin).
- Fix a build failure and remove a couple of redundant updates of
variables in the exynos-nocp devfreq driver (Axel Lin)"

New mount option "idsfromsid" indicates to cifs.ko that
it should try to retrieve the uid and gid owner fields
from special sids. This patch adds the code to parse the owner
sids in the ACL to see if they match, and if so populate the
uid and/or gid from them. This is faster than upcalling for
them and asking winbind, and is a fairly common case, and is
also helpful when cifs.upcall and idmapping is not configured.

When any leg(s) have failed, any read will cause a new operational
default leg to be selected and the read is resubmitted to it. If that
new default leg fails the read too, no other still accessible legs are
used to resubmit the read again -- thus failing the io.
Fix by allowing the read to get resubmitted until all operational legs
have been exhausted. Also, remove any details.bi_dev use as a flag.

default leg to be selected and the read is resubmitted. But until now
the read will return failure even though it was successful due to
resubmission. The reason for this is bio->bi_error was not being
cleared before resubmitting the bio.
Fix by clearing bio->bi_error before resubmission.

In cases where the number of tx rings is not a multiple of the number of
rx rings, the tx completion event will be handled on a different core
from the transmit and population of the ring. Races on the ring will
lead to a double-free of the page, and possibly other corruption.
The rings are initialized by default with a valid multiple of rings,
based on the number of cpus, therefore an invalid configuration requires
ethtool to change the ring layout. For instance 'ethtool -L eth0 rx 9 tx
8' will cause packets received on rx0, and XDP_TX'd to tx48, to be
completed on cpu3 (48 % 9 == 3).
Resolve this discrepancy by shifting the irq for the xdp tx queues to
start again from 0, modulo rx_ring_num.

qed: Fix dependencies and warnings series
The first patch in this series follows Dan Carpenter's reports about
Smatch warnings for recent qed additions and fixes those.
The second patch is the most significant one [and the reason this is
ntended for 'net'] - it's based on Arnd Bermann's suggestion for fixing
compilation issues that were introduced with the roce addition as a result
of certain combinations of qed, qede and qedr Kconfig options.
The third follows the discussion with Arnd and clears a lot of the warnings
that arise when compiling the drivers with "C=1".
Please consider applying this series to 'net'.

The qedr driver would require a tristate Kconfig option [to allow
it to compile as a module], and toward that end we've added the
INFINIBAND_QEDR option. But as we've made the compilation of the
qed/qede infrastructure required for RoCE dependent on the option
we'd be facing linking difficulties in case that QED=y or QEDE=y,
and INFINIBAND_QEDR=m.
To resolve this, we seperate between the INFINIBAND_QEDR option
and the infrastructure support in qed/qede by introducing a new
QED_RDMA option which would be selected by INFINIBAND_QEDR but would
be a boolean instead of a tristate; Following that, the qed/qede is
fixed based on this new option so that all config combinations would
be supported.

The IPv6 temporary address generation uses a variable called DESYNC_FACTOR
to prevent hosts updating the addresses at the same time. Quoting RFC 4941:
... The value DESYNC_FACTOR is a random value (different for each
client) that ensures that clients don't synchronize with each other and
generate new addresses at exactly the same time ...
DESYNC_FACTOR is defined as:
DESYNC_FACTOR -- A random value within the range 0 - MAX_DESYNC_FACTOR.
It is computed once at system start (rather than each time it is used)
and must never be greater than (TEMP_VALID_LIFETIME - REGEN_ADVANCE).
First, I believe the RFC has a typo in it and meant to say: "and must
never be greater than (TEMP_PREFERRED_LIFETIME - REGEN_ADVANCE)"
The reason is that at various places in the RFC, DESYNC_FACTOR is used in
a calculation like (TEMP_PREFERRED_LIFETIME - DESYNC_FACTOR) or
(TEMP_PREFERRED_LIFETIME - REGEN_ADVANCE - DESYNC_FACTOR). It needs to be
smaller than (TEMP_PREFERRED_LIFETIME - REGEN_ADVANCE) for the result of
these calculations to be larger than zero. It's never used in a
calculation together with TEMP_VALID_LIFETIME.
I already submitted an errata to the rfc-editor:
https://www.rfc-editor.org/errata_search.php?rfc=4941
The Linux implementation of DESYNC_FACTOR is very wrong:
max_desync_factor is used in places DESYNC_FACTOR should be used.
max_desync_factor is initialized to the RFC-recommended value for
MAX_DESYNC_FACTOR (600) but the whole point is to get a _random_ value.
And nothing ensures that the value used is not greater than
(TEMP_PREFERRED_LIFETIME - REGEN_ADVANCE), which leads to underflows. The
effect can easily be observed when setting the temp_prefered_lft sysctl
e.g. to 60. The preferred lifetime of the temporary addresses will be
bogus.
TEMP_PREFERRED_LIFETIME and REGEN_ADVANCE are not constants and can be
influenced by these three sysctls: regen_max_retry, dad_transmits and
temp_prefered_lft. Thus, the upper bound for desync_factor needs to be
re-calculated each time a new address is generated and if desync_factor is
larger than the new upper bound, a new random value needs to be
re-generated.
And since we already have max_desync_factor configurable per interface, we
also need to calculate and store desync_factor per interface.

The randomized interface identifier (rndid) was periodically updated from
the regen_timer timer. Simplify the code by updating the rndid only when
needed by ipv6_try_regen_rndid().
This makes the follow-up DESYNC_FACTOR fix much simpler. Also it fixes a
reference counting error in this error path, where an in6_dev_put was
missing:
err = addrconf_sysctl_register(ndev);
if (err) {
ipv6_mc_destroy_dev(ndev);
- del_timer(&ndev->regen_timer);
snmp6_unregister_dev(ndev);
goto err_release;

After the commit 9207f9d45b0a ("net: preserve IP control block
during GSO segmentation"), the GSO CB and the IPoIB CB conflict.
That destroy the IPoIB address information cached there,
causing a severe performance regression, as better described here:
http://marc.info/?l=linux-kernel&m=146787279825501&w=2
This change moves the data cached by the IPoIB driver from the
skb control lock into the IPoIB hard header, as done before
the commit 936d7de3d736 ("IPoIB: Stop lying about hard_header_len
and use skb->cb to stash LL addresses").
In order to avoid GRO issue, on packet reception, the IPoIB driver
stash into the skb a dummy pseudo header, so that the received
packets have actually a hard header matching the declared length.
To avoid changing the connected mode maximum mtu, the allocated
head buffer size is increased by the pseudo header length.
After this commit, IPoIB performances are back to pre-regression
value.
v2 -> v3: rebased
v1 -> v2: avoid changing the max mtu, increasing the head buf size

The driver only has runtime but no build time dependency with FSL_SOC ||
ARCH_MXC || ARCH_LAYERSCAPE. So it can be built for testing purposes if
the COMPILE_TEST option is enabled.
This is useful to have more build coverage and make sure that the driver
is not affected by changes that could cause build regressions.

When the device is registered via OF, the OF table is used to match the
driver instead of the SPI device ID table, but the entries in the later
are used as aliasses to load the module if the driver was not built-in.
This is because the SPI core always reports an SPI module alias instead
of an OF one, but that could change so it's better to always export it.

If the driver is built as a module, module alias information isn't filled
so the module won't be autoloaded. Add a SPI device ID table and use the
MODULE_DEVICE_TABLE() macro so the information is exported in the module.

The goal of the patch is to fix this scenario:
ip link add dummy1 type dummy
ip link set dummy1 up
ip link set lo down ; ip link set lo up
After that sequence, the local route to the link layer address of dummy1 is
not there anymore.
When the loopback is set down, all local routes are deleted by
addrconf_ifdown()/rt6_ifdown(). At this time, the rt6_info entry still
exists, because the corresponding idev has a reference on it. After the rcu
grace period, dst_rcu_free() is called, and thus ___dst_free(), which will
set obsolete to DST_OBSOLETE_DEAD.
In this case, init_loopback() is called before dst_rcu_free(), thus
obsolete is still sets to something <= 0. So, the function doesn't add the
route again. To avoid that race, let's check the rt6 refcnt instead.

Fixes: a881ae1f625c ("ipv6: don't call addrconf_dst_alloc again when enable lo")
