2016-10-10mmc: sdhci-of-arasan: add sdhci_arasan_voltage_switch for arasan, 5.1Shawn Lin
Per the vendor's requirement, we shouldn't do any setting for 1.8V Signaling Enable, otherwise the interaction/behaviour between phy and controller will be undefined. Mostly it works fine if we do that, but we still see failures. Anyway, let's fix it to meet the vendor's requirement. The error log looks like: [ 93.405085] mmc1: unexpected status 0x800900 after switch [ 93.408474] mmc1: switch to bus width 1 failed [ 93.408482] mmc1: mmc_select_hs200 failed, error -110 [ 93.408492] mmc1: error -110 during resume (card was removed?)

2016-10-10mmc: core: changes frequency to hs_max_dtr when selecting hs400esShawn Lin
Per JESD84-B51 P49, Host need to change frequency to <=52MHz after setting HS_TIMING to 0x1, and host may changes frequency to <= 200MHz after setting HS_TIMING to 0x3. That means the card expects the clock rate to increase from the current used f_init (which is less than 400KHz, but still being less than 52MHz) to 52MHz, otherwise we find some eMMC devices significantly report failure when sending status.

2016-10-10mmc: core: switch to 1V8 or 1V2 for hs400es modeShawn Lin
When introducing hs400es, I didn't notice that we haven't switched voltage to 1V2 or 1V8 for it. That happens to work as the first controller claiming to support hs400es, arasan(5.1), which is designed to only support 1V8. So the voltage is fixed to 1V8. But it actually is wrong, and will not fit for other host controllers. Let's fix it.

2016-10-10Revert "HID: dragonrise: fix HID Descriptor for 0x0006 PID"Ioan-Adrian Ratiu
This reverts commit 18339f59c3a6 ("HID: dragonrise: fix HID...") because it breaks certain dragonrise 0079:0006 gamepads. While it may fix a breakage caused by commit 79346d620e9d ("HID: input: force generic axis to be mapped to their user space axis"), it is probable that the manufacturer released different hardware with the same PID so this fix works for only a subset and breaks the other gamepads sharing the PID. What is needed is another more generic solution which fixes 79346d620e9d ("HID: input: force generic axis ...") breakage for this controller: we need to add an exception for this driver to make it keep the old behaviour previous to the initial breakage (this is done in patch 2 of this series).

2016-10-10HID: hid-dr: add input mapping for axis selectionIoan-Adrian Ratiu
Commit 79346d620e9d ("HID: input: force generic axis to be mapped to their user space axis") made mapping generic axes to their userspace equivalents mandatory and some lower end gamepads which were depending on the previous behaviour suffered severe regressions because they were reusing axes and expecting hid-input to multiplex their map to the respective userspace axis by always searching for and using the next available axis. One solution is to add a hid quirk for this type of "previous" behaviour in hid-input to bypass the new axes policy in favour of the old one, but since only one hardware vendor seems to be affected negatively we're better off making and exception and mapping in the driver for now; if more vendors or drivers turn out to experience the problem we should reconsider the quirk solution.

2016-10-10ACPI / fan: Fix error reading cur_stateSrinivas Pandruvada
On some platforms with ACPI4 variable speed fan, reading cur_state from cooling device returns "invalid value" error. This confuses user space applications. This issue occurs as the current driver doesn't take account of "FineGrainControl" from _FIF(Fan Information). When the "FineGrainControl" is set, _FSL(FSL Set Level) takes argument as a percent, which doesn't have to match from any control value from _FPS(Fan Performance States). It is also possible that the Fan is not actually running at the requested speed returning a lower speed. On some platforms the BIOS is setting fan speed to a level during boot, which will not have an exact match to _FPS control values. The current implementation will treat this level as invalid value. The simple change is to atleast return state corresponding to a maximum control value in the _FPS compared to the current level.

2016-10-09printk: reinstate KERN_CONT for printing continuation linesLinus Torvalds
Long long ago the kernel log buffer was a buffered stream of bytes, very much like stdio in user space. It supported log levels by scanning the stream and noticing the log level markers at the beginning of each line, but if you wanted to print a partial line in multiple chunks, you just did multiple printk() calls, and it just automatically worked. Except when it didn't, and you had very confusing output when different lines got all mixed up with each other. Then you got fragment lines mixing with each other, or with non-fragment lines, because it was traditionally impossible to tell whether a printk() call was a continuation or not. To at least help clarify the issue of continuation lines, we added a KERN_CONT marker back in 2007 to mark continuation lines: 474925277671 ("printk: add KERN_CONT annotation"). That continuation marker was initially an empty string, and didn't actuall make any semantic difference. But it at least made it possible to annotate the source code, and have check-patch notice that a printk() didn't need or want a log level marker, because it was a continuation of a previous line. To avoid the ambiguity between a continuation line that had that KERN_CONT marker, and a printk with no level information at all, we then in 2009 made KERN_CONT be a real log level marker which meant that we could now reliably tell the difference between the two cases. 5fd29d6ccbc9 ("printk: clean up handling of log-levels and newlines") and we could take advantage of that to make sure we didn't mix up continuation lines with lines that just didn't have any loglevel at all. Then, in 2012, the kernel log buffer was changed to be a "record" based log, where each line was a record that has a loglevel and a timestamp. You can see the beginning of that conversion in commits e11fea92e13f ("kmsg: export printk records to the /dev/kmsg interface") 7ff9554bb578 ("printk: convert byte-buffer to variable-length record buffer") with a number of follow-up commits to fix some painful fallout from that conversion. Over all, it took a couple of months to sort out most of it. But the upside was that you could have concurrent readers (and writers) of the kernel log and not have lines with mixed output in them. And one particular pain-point for the record-based kernel logging was exactly the fragmentary lines that are generated in smaller chunks. In order to still log them as one recrod, the continuation lines need to be attached to the previous record properly. However the explicit continuation record marker that is actually useful for this exact case was actually removed in aroundm the same time by commit 61e99ab8e35a ("printk: remove the now unnecessary "C" annotation for KERN_CONT") due to the incorrect belief that KERN_CONT wasn't meaningful. The ambiguity between "is this a continuation line" or "is this a plain printk with no log level information" was reintroduced, and in fact became an even bigger pain point because there was now the whole record-level merging of kernel messages going on. This patch reinstates the KERN_CONT as a real non-empty string marker, so that the ambiguity is fixed once again. But it's not a plain revert of that original removal: in the four years since we made KERN_CONT an empty string again, not only has the format of the log level markers changed, we've also had some usage changes in this area. For example, some ACPI code seems to use KERN_CONT _together_ with a log level, and now uses both the KERN_CONT marker and (for example) a KERN_INFO marker to show that it's an informational continuation of a line. Which is actually not a bad idea - if the continuation line cannot be attached to its predecessor, without the log level information we don't know what log level to assign to it (and we traditionally just assigned it the default loglevel). So having both a log level and the KERN_CONT marker is not necessarily a bad idea, but it does mean that we need to actually iterate over potentially multiple markers, rather than just a single one. Also, since KERN_CONT was still conceptually needed, and encouraged, but didn't actually _do_ anything, we've also had the reverse problem: rather than having too many annotations it has too few, and there is bit rot with code that no longer marks the continuation lines with the KERN_CONT marker. So this patch not only re-instates the non-empty KERN_CONT marker, it also fixes up the cases of bit-rot I noticed in my own logs. There are probably other cases where KERN_CONT will be needed to be added, either because it is new code that never dealt with the need for KERN_CONT, or old code that has bitrotted without anybody noticing. That said, we should strive to avoid the need for KERN_CONT. It does result in real problems for logging, and should generally not be seen as a good feature. If we some day can get rid of the feature entirely, because nobody does any fragmented printk calls, that would be lovely. But until that point, let's at mark the code that relies on the hacky multi-fragment kernel printk's. Not only does it avoid the ambiguity, it also annotates code as "maybe this would be good to fix some day". (That said, particularly during single-threaded bootup, the downsides of KERN_CONT are very limited. Things get much hairier when you have multiple threads going on and user level reading and writing logs too). Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2016-10-09cpufreq: intel_pstate: Fix unsafe HWP MSR accessSrinivas Pandruvada
This is a requirement that MSR MSR_PM_ENABLE must be set to 0x01 before reading MSR_HWP_CAPABILITIES on a given CPU. If cpufreq init() is scheduled on a CPU which is not same as policy->cpu or migrates to a different CPU before calling msr read for MSR_HWP_CAPABILITIES, it is possible that MSR_PM_ENABLE was not to set to 0x01 on that CPU. This will cause GP fault. So like other places in this path rdmsrl_on_cpu should be used instead of rdmsrl. Moreover the scope of MSR_HWP_CAPABILITIES is on per thread basis, so it should be read from the same CPU, for which MSR MSR_HWP_REQUEST is getting set. dmesg dump or warning: [ 22.014488] WARNING: CPU: 139 PID: 1 at arch/x86/mm/extable.c:50 ex_handler_rdmsr_unsafe+0x68/0x70 [ 22.014492] unchecked MSR access error: RDMSR from 0x771 [ 22.014493] Modules linked in: [ 22.014507] CPU: 139 PID: 1 Comm: swapper/0 Not tainted 4.7.5+ #1 ... ...

2016-10-07xen-netback: make sure that hashes are not send to unaware frontendsPaul Durrant
In the case when a frontend only negotiates a single queue with xen- netback it is possible for a skbuff with a s/w hash to result in a hash extra_info segment being sent to the frontend even when no hash algorithm has been configured. (The ndo_select_queue() entry point makes sure the hash is not set if no algorithm is configured, but this entry point is not called when there is only a single queue). This can result in a frontend that is unable to handle extra_info segments being given such a segment, causing it to crash. This patch fixes the problem by clearing the hash in ndo_start_xmit() instead, which is clearly guaranteed to be called irrespective of the number of queues.
