2016-10-10drm/i915: Restore current RPS state after resetChris Wilson
Following commit 821ed7df6e2a ("drm/i915: Update reset path to fix incomplete requests") we no longer mark the context as lost on reset as we keep the requests (and contexts) alive. However, RPS remains reset and we need to restore the current state to match the in-flight requests.

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>

2016-10-07xen-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.

2016-10-07console: don't prefer first registered if DT specifies stdout-pathPaul Burton
If a device tree specifies a preferred device for kernel console output via the stdout-path or linux,stdout-path chosen node properties or the stdout alias then the kernel ought to honor it & output the kernel console to that device. As it stands, this isn't the case. Whilst we parse the stdout-path properties & set an of_stdout variable from of_alias_scan(), and use that from of_console_check() to determine whether to add a console device as a preferred console whilst registering it, we also prefer the first registered console if no other has been selected at the time of its registration. This means that if a console other than the one the device tree selects via stdout-path is registered first, we will switch to using it & when the stdout-path console is later registered the call to add_preferred_console() via of_console_check() is too late to do anything useful. In practice this seems to mean that we switch to the dummy console device fairly early & see no further console output: Console: colour dummy device 80x25 console [tty0] enabled bootconsole [ns16550a0] disabled Fix this by not automatically preferring the first registered console if one is specified by the device tree. This allows consoles to be registered but not enabled, and once the driver for the console selected by stdout-path calls of_console_check() the driver will be added to the list of preferred consoles before any other console has been enabled. When that console is then registered via register_console() it will be enabled as expected.

2016-10-07cred: simpler, 1D supplementary groupsAlexey Dobriyan
Current supplementary groups code can massively overallocate memory and is implemented in a way so that access to individual gid is done via 2D array. If number of gids is <= 32, memory allocation is more or less tolerable (140/148 bytes). But if it is not, code allocates full page (!) regardless and, what's even more fun, doesn't reuse small 32-entry array. 2D array means dependent shifts, loads and LEAs without possibility to optimize them (gid is never known at compile time). All of the above is unnecessary. Switch to the usual trailing-zero-len-array scheme. Memory is allocated with kmalloc/vmalloc() and only as much as needed. Accesses become simpler (LEA 8(gi,idx,4) or even without displacement). Maximum number of gids is 65536 which translates to 256KB+8 bytes. I think kernel can handle such allocation. On my usual desktop system with whole 9 (nine) aux groups, struct group_info shrinks from 148 bytes to 44 bytes, yay! Nice side effects: - "gi->gid[i]" is shorter than "GROUP_AT(gi, i)", less typing, - fix little mess in net/ipv4/ping.c should have been using GROUP_AT macro but this point becomes moot, - aux group allocation is persistent and should be accounted as such.

2016-10-07nmi_backtrace: generate one-line reports for idle cpusChris Metcalf
When doing an nmi backtrace of many cores, most of which are idle, the output is a little overwhelming and very uninformative. Suppress messages for cpus that are idling when they are interrupted and just emit one line, "NMI backtrace for N skipped: idling at pc 0xNNN". We do this by grouping all the cpuidle code together into a new .cpuidle.text section, and then checking the address of the interrupted PC to see if it lies within that section. This commit suitably tags x86 and tile idle routines, and only adds in the minimal framework for other architectures.

2016-10-07/dev/dax: fix Kconfig dependency build breakageRoss Zwisler
The function dax_pmem_probe() in drivers/dax/pmem.c is compiled under the CONFIG_DEV_DAX_PMEM tri-state config option. This config option currently only depends on CONFIG_NVDIMM_DAX, a bool, which means that the following configuration is possible: CONFIG_LIBNVDIMM=m ... CONFIG_NVDIMM_DAX=y CONFIG_DEV_DAX=y CONFIG_DEV_DAX_PMEM=y With this config LIBNVDIMM is compiled as a module with NVDIMM_DAX=y just meaning that we will compile drivers/nvdimm/dax_devs.c into that module. However, dax_pmem_probe() depends on several symbols defined in drivers/nvdimm/dax_devs.c, which results in the following build errors: drivers/built-in.o: In function `dax_pmem_probe': linux/drivers/dax/pmem.c:70: undefined reference to `to_nd_dax' linux/drivers/dax/pmem.c:74: undefined reference to `nvdimm_namespace_common_probe' linux/drivers/dax/pmem.c:80: undefined reference to `devm_nsio_enable' linux/drivers/dax/pmem.c:81: undefined reference to `nvdimm_setup_pfn' linux/drivers/dax/pmem.c:84: undefined reference to `devm_nsio_disable' linux/drivers/dax/pmem.c:122: undefined reference to `to_nd_region' drivers/built-in.o: In function `dax_pmem_init': linux/drivers/dax/pmem.c:147: undefined reference to `__nd_driver_register' Fix this by making NVDIMM_DAX a tristate. DEV_DAX_PMEM depends on NVDIMM_DAX which depends on LIBNVDIMM. Since they are all now tristates, if LIBNVDIMM is built as a kernel module DEV_DAX_PMEM will be as well. This prevents dax_devs.c from being built as a built-in while its dependencies are in the libnvdimm.ko module.

We changed one of the RDMA APIs and Lustre's InfiniBand transport has not been updated to match. Disabled it for now. Signed-off-by: Doug Ledford <dledford@redhat.com>
2016-10-07iw_cxgb4: add fast-path for small REG_MR operationsSteve Wise
When processing a REG_MR work request, if fw supports the FW_RI_NSMR_TPTE_WR work request, and if the page list for this registration is <= 2 pages, and the current state of the mr is INVALID, then use FW_RI_NSMR_TPTE_WR to pass down a fully populated TPTE for FW to write. This avoids FW having to do an async read of the TPTE blocking the SQ until the read completes. To know if the current MR state is INVALID or not, iw_cxgb4 must track the state of each fastreg MR. The c4iw_mr struct state is updated as REG_MR and LOCAL_INV WRs are posted and completed, when a reg_mr is destroyed, and when RECV completions are processed that include a local invalidation. This optimization increases small IO IOPS for both iSER and NVMF. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
2016-10-07cxgb4: advertise support for FR_NSMR_TPTE_WRSteve Wise
Query firmware for the FW_PARAMS_PARAM_DEV_RI_FR_NSMR_TPTE_WR parameter. If it exists and is 1, then advertise support for FR_NSMR_TPTE_WR to the ULDs. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
