When converting from text to rst, the kobjects section and its sole subsection about device tree nodes were coalesced into a single section, yielding an inconsistent result. Remove all references to kobjects, as 1. Device tree object pointers are not compatible to kobject pointers (the former may embed the latter, though), and 2. there are no printk formats defined for kobject types.

2018-10-12Documentation: preempt-locking: Use better exampleAndrew Murray
The existing wording implies that the use of spin_unlock whilst irqs are disabled might trigger a reschedule. However the preemptible() test in preempt_schedule will prevent a reschedule if irqs are disabled. Lets improve the clarity of this wording to change the example from spin_unlock to cond_resched() and cond_resched_lock() as these are functions that will trigger a reschedule if the preempt count is 0 without testing that irqs are disabled. Also remove the 'Last Updated' line as this is not up to date and better tracked via GIT. Signed-off-by: Andrew Murray <andrew.murray@arm.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2018-10-12sparc: Fix single-pcr perf event counter management.David S. Miller
It is important to clear the hw->state value for non-stopped events when they are added into the PMU. Otherwise when the event is scheduled out, we won't read the counter because HES_UPTODATE is still set. This breaks 'perf stat' and similar use cases, causing all the events to show zero. This worked for multi-pcr because we make explicit sparc_pmu_start() calls in calculate_multiple_pcrs(). calculate_single_pcr() doesn't do this because the idea there is to accumulate all of the counter settings into the single pcr value. So we have to add explicit hw->state handling there. Like x86, we use the PERF_HES_ARCH bit to track truly stopped events so that we don't accidently start them on a reload. Related to all of this, sparc_pmu_start() is missing a userpage update so add it. Signed-off-by: David S. Miller <davem@davemloft.net>

2018-10-12net: bridge: add support for per-port vlan statsNikolay Aleksandrov
This patch adds an option to have per-port vlan stats instead of the default global stats. The option can be set only when there are no port vlans in the bridge since we need to allocate the stats if it is set when vlans are being added to ports (and respectively free them when being deleted). Also bump RTNL_MAX_TYPE as the bridge is the largest user of options. The current stats design allows us to add these without any changes to the fast-path, it all comes down to the per-vlan stats pointer which, if this option is enabled, will be allocated for each port vlan instead of using the global bridge-wide one.

2018-10-12regulator/gpio: Allow nonexclusive GPIO accessLinus Walleij
This allows nonexclusive (simultaneous) access to a single GPIO line for the fixed regulator enable line. This happens when several regulators use the same GPIO for enabling and disabling a regulator, and all need a handle on their GPIO descriptor. This solution with a special flag is not entirely elegant and should ideally be replaced by something more careful as this makes it possible for several consumers to enable/disable the same GPIO line to the left and right without any consistency. The current use inside the regulator core should however be fine as it takes special care to handle this. For the state of the GPIO backend, this is still the lesser evil compared to going back to global GPIO numbers.

2018-10-12net: Evict neighbor entries on carrier downDavid Ahern
When a link's carrier goes down it could be a sign of the port changing networks. If the new network has overlapping addresses with the old one, then the kernel will continue trying to use neighbor entries established based on the old network until the entries finally age out - meaning a potentially long delay with communications not working. This patch evicts neighbor entries on carrier down with the exception of those marked permanent. Permanent entries are managed by userspace (either an admin or a routing daemon such as FRR).

2018-10-12net/ipv6: Add knob to skip DELROUTE message on device downDavid Ahern
Another difference between IPv4 and IPv6 is the generation of RTM_DELROUTE notifications when a device is taken down (admin down) or deleted. IPv4 does not generate a message for routes evicted by the down or delete; IPv6 does. A NOS at scale really needs to avoid these messages and have IPv4 and IPv6 behave similarly, relying on userspace to handle link notifications and evict the routes. At this point existing user behavior needs to be preserved. Since notifications are a global action (not per app) the only way to preserve existing behavior and allow the messages to be skipped is to add a new sysctl (net/ipv6/route/skip_notify_on_dev_down) which can be set to disable the notificatioons. IPv6 route code already supports the option to skip the message (it is used for multipath routes for example). Besides the new sysctl we need to pass the skip_notify setting through the generic fib6_clean and fib6_walk functions to fib6_clean_node and to set skip_notify on calls to __ip_del_rt for the addrconf_ifdown path.

2018-10-12nvdimm: Use namespace index data to reduce number of label reads neededAlexander Duyck
This patch adds logic that is meant to make use of the namespace index data to reduce the number of reads that are needed to initialize a given namespace. The general idea is that once we have enough data to validate the namespace index we do so and then proceed to fetch only those labels that are not listed as being "free". By doing this I am seeing a total time reduction from about 4-5 seconds to 2-3 seconds for 24 NVDIMM modules each with 128K of label config area.

2018-10-12nvdimm: Split label init out from the logic for getting config dataAlexander Duyck
This patch splits the initialization of the label data into two functions. One for doing the init, and another for reading the actual configuration data. The idea behind this is that by doing this we create a symmetry between the getting and setting of config data in that we have a function for both. In addition it will make it easier for us to identify the bits that are related to init versus the pieces that are a wrapper for reading data from the ACPI interface. So for example by splitting things out like this it becomes much more obvious that we were performing checks that weren't necessarily related to the set/get operations such as relying on ndd->data being present when the set and get ops should not care about a locally cached copy of the label area.

2018-10-12nvdimm: Clarify comment in sizeof_namespace_indexAlexander Duyck
When working on the label code I found it rather confusing to see several spots that reference a minimum label size of 256 while working with labels that are 128 bytes in size. This patch is meant to provide a clarification on one of the comments that was at the heart of the issue. Specifically for version 1.2 and later of the namespace specification the minimum label size is 256, prior to that the minimum label size was 128. So we should state that as such to avoid confusion.
