2018-06-01ip6_tunnel: remove magic mtu value 0xFFF8Nicolas Dichtel
I don't know where this value comes from (probably a copy and paste and paste and paste ...). Let's use standard values which are a bit greater.

2018-06-01ip_tunnel: restore binding to ifaces with a large mtuNicolas Dichtel
After commit f6cc9c054e77, the following conf is broken (note that the default loopback mtu is 65536, ie IP_MAX_MTU + 1): $ ip tunnel add gre1 mode gre local 10.125.0.1 remote 10.125.0.2 dev lo add tunnel "gre0" failed: Invalid argument $ ip l a type dummy $ ip l s dummy1 up $ ip l s dummy1 mtu 65535 $ ip tunnel add gre1 mode gre local 10.125.0.1 remote 10.125.0.2 dev dummy1 add tunnel "gre0" failed: Invalid argument dev_set_mtu() doesn't allow to set a mtu which is too large. First, let's cap the mtu returned by ip_tunnel_bind_dev(). Second, remove the magic value 0xFFF8 and use IP_MAX_MTU instead. 0xFFF8 seems to be there for ages, I don't know why this value was used. With a recent kernel, it's also possible to set a mtu > IP_MAX_MTU: $ ip l s dummy1 mtu 66000 After that patch, it's also possible to bind an ip tunnel on that kind of interface.

2018-06-01ASoC: topology: Improve backwards compatibility with v4 topology filesGuenter Roeck
Commit dc31e741db49 ("ASoC: topology: ABI - Add the types for BE DAI") introduced sound topology files version 5. Initially, this change made the topology code incompatible with v4 topology files. Backwards compatibility with v4 configuration files was subsequently added with commit 288b8da7e992 ("ASoC: topology: Support topology file of ABI v4"). Unfortunately, backwards compatibility was never fully implemented. First, the manifest size in (Skylake) v4 configuration files is set to 0, which causes manifest_new_ver() to bail out with error messages similar to the following. snd_soc_skl 0000:00:1f.3: ASoC: invalid manifest size snd_soc_skl 0000:00:1f.3: tplg component load failed-22 snd_soc_skl 0000:00:1f.3: Failed to init topology! snd_soc_skl 0000:00:1f.3: ASoC: failed to probe component -22 skl_n88l25_m98357a skl_n88l25_m98357a: ASoC: failed to instantiate card -22 skl_n88l25_m98357a: probe of skl_n88l25_m98357a failed with error -22 After this problem is fixed, the following error message is seen instead. snd_soc_skl 0000:00:1f.3: ASoC: old version of manifest snd_soc_skl 0000:00:1f.3: Invalid descriptor token 1093938482 snd_soc_skl 0000:00:1f.3: ASoC: failed to load widget media0_in cpr 0 snd_soc_skl 0000:00:1f.3: tPlg component load failed-22 This message is seen because backwards compatibility for loading widgets was never implemented. The lack of audio support when running the upstream kernel on recent Chromebooks has been reported in various forums, and can be traced back to this problem. Attempts to fix the problem, usually by providing v5 configuration files, were only partially successful. Let's implement backward compatibility properly to solve the problem for good.

2018-06-01tools/power turbostat: fix printing on inputArtem Bityutskiy
The recent patch that implements table printing on a keypress introduced a regression - turbostat prints the table almost continuously if it is run from a daemon program. The problem is also easy to reproduce like this: echo | turbostat The reason is that we cannot assume that stdin is always a TTY. It can be many things. This patch adds fixes the problem by limiting the new keypress functionality to TTYs only. If stdin is not a TTY, we just sleep for the full interval time. While on it, clean-up 'do_sleep()' to return no value, as callers do not expect that anyway.

2018-06-01tools/power turbostat: end current interval upon newline inputLen Brown
In turbostat interval mode, a newline typed on standard input will now conclude the current interval. Data will immediately be collected and printed for that interval, and the next interval will be started. This is similar to the recently added SIGUSR1 feature.

2018-06-01tools/power turbostat: on SIGUSR1: sample, print and continueLen Brown
Interval-mode turbostat now catches and discards SIGUSR1. Thus, SIGUSR1 can be used to tell turbostat to cut short the current measurement interval. Turbostat will then start the next measurement interval using the regular interval length. This can be used to give turbostat variable intervals. Invoke turbostat with --interval LARGE_NUMBER_SEC and have a program that has permission to send it a SIGUSR1 always before LARGE_NUMBER_SEC expires. It may also be useful to use "--enable Time_Of_Day_Seconds" to observe the actual interval length. Signed-off-by: Len Brown <len.brown@intel.com>

2018-06-01net: mvpp2: Split the PPv2 driver to a dedicated directoryMaxime Chevallier
As the mvpp2 driver is growing, move this driver to a dedicated directory and split it into several files. Since this driver has a lot of register defines and structure definitions, it can benefit from having all of this into a dedicated header file, named mvpp2.h. A good chunk of the mvpp2 code is dedicated to Header Parser handling, so we introduce mvpp2_prs.h where all Header Parser definitions are located, and mvpp2_prs.c containing the related code. In the same way, mvpp2_cls.h and mvpp2_cls.c are created to contain Classifier and RSS related code. The former 'mvpp2.c' file is renamed 'mvpp2_main.c' so that we can keep the driver binary named 'mvpp2'. This commit is only about spliting the driver into multiple files and doesn't introduce any new function, feature or fix besides removing 'static' keywords when needed.

tc_ctl_tfilter handles three netlink message types: RTM_NEWTFILTER, RTM_DELTFILTER, RTM_GETTFILTER. However, implementation of this function involves a lot of branching on specific message type because most of the code is message-specific. This significantly complicates adding new functionality and doesn't provide much benefit of code reuse. Split tc_ctl_tfilter to three standalone functions that handle filter new, delete and get requests.

2018-06-01lightnvm: pass flag on graceful teardown to targetsJavier González
If the namespace is unregistered before the LightNVM target is removed (e.g., on hot unplug) it is too late for the target to store any metadata on the device - any attempt to write to the device will fail. In this case, pass on a "gracefull teardown" flag to the target to let it know when this happens. In the case of pblk, we pad the open line (close all open chunks) to improve data retention. In the event of an ungraceful shutdown, avoid this part and just clean up.

2018-06-01lightnvm: pblk: warn in case of corrupted write bufferJavier González
When cleaning up buffer entries as we wrap up, their state should be "completed". If any of the entries is in "submitted" state, it means that something bad has happened. Trigger a warning immediately instead of waiting for the state flag to eventually be updated, thus hiding the issue.

2018-06-01lightnvm: pblk: improve error msg on corrupted LBAsJavier González
In the event of a mismatch between the read LBA and the metadata pointer reported by the device, improve the error message to be able to detect the offending physical address (PPA) mapped to the corrupted LBA.
