2019-07-18mm: thp: fix false negative of shmem vma's THP eligibilityYang Shi1-2/+2
Commit 7635d9cbe832 ("mm, thp, proc: report THP eligibility for each vma") introduced THPeligible bit for processes' smaps. But, when checking the eligibility for shmem vma, __transparent_hugepage_enabled() is called to override the result from shmem_huge_enabled(). It may result in the anonymous vma's THP flag override shmem's. For example, running a simple test which create THP for shmem, but with anonymous THP disabled, when reading the process's smaps, it may show: 7fc92ec00000-7fc92f000000 rw-s 00000000 00:14 27764 /dev/shm/test Size: 4096 kB ... [snip] ... ShmemPmdMapped: 4096 kB ... [snip] ... THPeligible: 0 And, /proc/meminfo does show THP allocated and PMD mapped too: ShmemHugePages: 4096 kB ShmemPmdMapped: 4096 kB This doesn't make too much sense. The shmem objects should be treated separately from anonymous THP. Calling shmem_huge_enabled() with checking MMF_DISABLE_THP sounds good enough. And, we could skip stack and dax vma check since we already checked if the vma is shmem already. Also check if vma is suitable for THP by calling transhuge_vma_suitable(). And minor fix to smaps output format and documentation.

Pull clk updates from Stephen Boyd: "This round of clk driver and framework updates is heavy on the driver update side. The two main highlights in the core framework are the addition of an bulk clk_get API that handles optional clks and an extra debugfs file that tells the developer about the current parent of a clk. The driver updates are dominated by i.MX in the diffstat, but that is mostly because that SoC has started converting to the clk_hw style of clk registration. The next big update is in the Amlogic meson clk driver that gained some support for audio, cpu, and temperature clks while fixing some PLL issues. Finally, the biggest thing that stands out is the conversion of a large part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses less strings and more pointer comparisons to match clk parents and children up. In general, it looks like we have a lot of little fixes and tweaks here and there to clk data along with the normal addition of a handful of new drivers and a couple new core framework features.

2019-07-17platform/x86: asus: Rename "fan mode" to "fan boost mode"Daniel Drake1-3/+3
The Asus WMI spec indicates that the function being controlled here is called "Fan Boost Mode". The user-facing documentation also calls it this. The spec uses the term "fan mode" is used to refer to other things, including functionality expected to appear on future products. We missed this before as we are not dealing with the most readable of specs, and didn't forsee any confusion around shortening the name. Rename "fan mode" to "fan boost mode" to improve consistency with the spec and to avoid a future naming conflict. There is no interface breakage here since this has yet to be included in an official kernel release. I also updated the kernel version listed under ABI accordingly.

2019-07-16coda: stop using 'struct timespec' in user APIArnd Bergmann1-4/+7
We exchange file timestamps with user space using psdev device read/write operations with a fixed but architecture specific binary layout. On 32-bit systems, this uses a 'timespec' structure that is defined by the C library to contain two 32-bit values for seconds and nanoseconds. As we get ready for the year 2038 overflow of the 32-bit signed seconds, the kernel now uses 64-bit timestamps internally, and user space will do the same change by changing the 'timespec' definition in the future. Unfortunately, this breaks the layout of the coda_vattr structure, so we need to redefine that in terms of something that does not change. I'm introducing a new 'struct vtimespec' structure here that keeps the existing layout, and the same change has to be done in the coda user space copy of linux/coda.h before anyone can use that on a 32-bit architecture with 64-bit time_t. An open question is what should happen to actual times past y2038, as they are now truncated to the last valid date when sent to user space, and interpreted as pre-1970 times when a timestamp with the MSB set is read back into the kernel. Alternatively, we could change the new timespec64_to_coda()/coda_to_timespec64() functions to use a different interpretation and extend the available range further to the future by disallowing past timestamps. This would require more changes in the user space side though.

2019-07-16vmcore: add a kernel parameter novmcoreddKairui Song1-0/+11
Since commit 2724273e8fd0 ("vmcore: add API to collect hardware dump in second kernel"), drivers are allowed to add device related dump data to vmcore as they want by using the device dump API. This has a potential issue, the data is stored in memory, drivers may append too much data and use too much memory. The vmcore is typically used in a kdump kernel which runs in a pre-reserved small chunk of memory. So as a result it will make kdump unusable at all due to OOM issues. So introduce new 'novmcoredd' command line option. User can disable device dump to reduce memory usage. This is helpful if device dump is using too much memory, disabling device dump could make sure a regular vmcore without device dump data is still available.

2019-07-15docs: add some directories to the main documentation indexMauro Carvalho Chehab13-12/+25
The contents of those directories were orphaned at the documentation body. While those directories could likely be moved to be inside some guide, I'm opting to just adding their indexes to the main one, removing the :orphan: and adding the SPDX header. For the drivers, the rationale is that the documentation contains a mix of Kernelspace, uAPI and admin-guide. So, better to keep them on separate directories, as we've be doing with similar subsystem-specific docs that were not split yet. For the others, well... I'm too lazy to do the move. Also, it seems to make sense to keep at least some of those at the main dir (like kbuild, for example). In any case, a latter patch could do the move.
