Pull ARM SoC 64-bit changes from Olof Johansson: "Changes to platform code for 64-bit ARM platforms. Most of these are small changes to the one defconfig we use on arm64 (no per-platform configs there), to enable new drivers. There are also a few other changes.

Pull ARM Device-tree updates from Olof Johansson: "Device-tree continues to see lots of updates. The majority of patches here are smaller changes for new hardware on existing platforms, and there are a few larger changes worth pointing out. Major new platforms: - Gemini has been ported to DT, so a handful of "new" platforms moved over from board files - Rockchip RK3288 support for Tinkerboard and Phytec phyCORE-RK3288 SoM and RDK - A bunch of embedded platforms, several Linksys platforms, Synology DS116, - Motorola Droid4 (really old OMAP-based phone) support is added. Some refactorings, i.e. Allwinner H3/H5 support is commonalized. And lots of smaller changes, cleanups, etc. See shortlog for more description We're adding ability to cross-include DT files between arm and arm64, by creating appropriate links in the dt-include directory, and using arm/ and arm64/ as include prefixes. This will avoid other local hacks such as per-file links between the two arch trees (this broke for external mirroring of DT contents).

We fixed the bugs in it, but it's still an ugly interface, so let's see if anybody actually depends on it. It's entirely possible that nothing actually requires the whole "punch through read-only mappings" semantics. For example, gdb definitely uses the /proc/<pid>/mem interface, but it looks like it mainly does it for regular reads of the target (that don't need FOLL_FORCE), and looking at the gdb source code seems to fall back on the traditional ptrace(PTRACE_POKEDATA) interface if it needs to. If this breaks something, I do have a (more complex) version that only enables FOLL_FORCE when somebody has PTRACE_ATTACH'ed to the target, like the comment here used to say ("Maybe we should limit FOLL_FORCE to actual ptrace users?").

Pull more tracing updates from Steven Rostedt: "These are three simple changes. The first one is just a switch from using strcpy() to strlcpy(). Someone thought that it may cause an overflow bug, but since it only copies comms into a pre-allocated array of TASK_COMM_LEN, and no comm should ever be bigger than that, nor not end with a nul character, this change is more of a safety precaution than fixing anything that is actually broken.

Merge tags 'for-linus' and 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull more rdma updates from Doug Ledford: "As mentioned in my first pull request, this is the subsequent pull requests I had. This is all I have, and in fact this cleans out the RDMA subsystem's entire patchworks queue of kernel changes that are ready to go (well, it did for the weekend anyway, a few new patches are in, but they'll be coming during the -rc cycle). The first tag contains a single patch that would have conflicted if taken from my tree or DaveM's tree as it needed our trees merged to come cleanly. The second tag contains the patch series from Intel plus three other stragllers that came in late last week. I took them because it allowed me to legitimately claim that the RDMA patchworks queue was, for a short time, 100% cleared of all waiting kernel patches, woohoo! :-). I have it under my for-next tag, so it did get 0day and linux- next over the end of last week, and linux-next did show one minor conflict.

Patch series "second round of tracepoints for DAX". This second round of DAX tracepoint patches adds tracing to the PTE fault path (dax_iomap_pte_fault(), dax_pfn_mkwrite(), dax_load_hole(), dax_insert_mapping()) and to the writeback path (dax_writeback_mapping_range(), dax_writeback_one()). The purpose of this tracing is to give us a high level view of what DAX is doing, whether faults are being serviced by PMDs or PTEs, and by real storage or by zero pages covering holes. I do have some patches nearly ready which also add tracing to grab_mapping_entry() and dax_insert_mapping_entry(). These are more targeted at logging how we are interacting with the radix tree, how we use empty entries for locking, whether we "downgrade" huge zero pages to 4k PTE sized allocations, etc. In the end it seemed to me that this might be too detailed to have as constantly present tracepoints, but if anyone sees value in having tracepoints like this in the DAX code permanently (Jan?), please let me know and I'll add those last two patches. All these tracepoints were done to be consistent with the style of the XFS tracepoints and with the existing DAX PMD tracepoints. This patch (of 6): Add tracepoints to dax_iomap_pte_fault(), following the same logging conventions as the rest of DAX. Here is an example fault that initially tries to be serviced by the PMD fault handler but which falls back to PTEs because the VMA isn't large enough to hold a PMD: small-1086 [005] .... 71.140014: xfs_filemap_huge_fault: dev 259:0 ino 0x1003 small-1086 [005] .... 71.140027: dax_pmd_fault: dev 259:0 ino 0x1003 shared WRITE|ALLOW_RETRY|KILLABLE|USER address 0x10420000 vm_start 0x10200000 vm_end 0x10500000 pgoff 0x220 max_pgoff 0x1400 small-1086 [005] .... 71.140028: dax_pmd_fault_done: dev 259:0 ino 0x1003 shared WRITE|ALLOW_RETRY|KILLABLE|USER address 0x10420000 vm_start 0x10200000 vm_end 0x10500000 pgoff 0x220 max_pgoff 0x1400 FALLBACK small-1086 [005] .... 71.140035: dax_pte_fault: dev 259:0 ino 0x1003 shared WRITE|ALLOW_RETRY|KILLABLE|USER address 0x10420000 pgoff 0x220 small-1086 [005] .... 71.140396: dax_pte_fault_done: dev 259:0 ino 0x1003 shared WRITE|ALLOW_RETRY|KILLABLE|USER address 0x10420000 pgoff 0x220 MAJOR|NOPAGE Link: http://lkml.kernel.org/r/20170221195116.13278-2-ross.zwisler@linux.intel.comSigned-off-by:

The previous patch ("mm: prevent potential recursive reclaim due to clearing PF_MEMALLOC") has shown that simply setting and clearing PF_MEMALLOC in current->flags can result in wrongly clearing a pre-existing PF_MEMALLOC flag and potentially lead to recursive reclaim. Let's introduce helpers that support proper nesting by saving the previous stat of the flag, similar to the existing memalloc_noio_* and memalloc_nofs_* helpers. Convert existing setting/clearing of PF_MEMALLOC within mm to the new helpers. There are no known issues with the converted code, but the change makes it more robust.

Patch series "more robust PF_MEMALLOC handling" This series aims to unify the setting and clearing of PF_MEMALLOC, which prevents recursive reclaim. There are some places that clear the flag unconditionally from current->flags, which may result in clearing a pre-existing flag. This already resulted in a bug report that Patch 1 fixes (without the new helpers, to make backporting easier). Patch 2 introduces the new helpers, modelled after existing memalloc_noio_* and memalloc_nofs_* helpers, and converts mm core to use them. Patches 3 and 4 convert non-mm code. This patch (of 4): __alloc_pages_direct_compact() sets PF_MEMALLOC to prevent deadlock during page migration by lock_page() (see the comment in __unmap_and_move()). Then it unconditionally clears the flag, which can clear a pre-existing PF_MEMALLOC flag and result in recursive reclaim. This was not a problem until commit a8161d1e ("mm, page_alloc: restructure direct compaction handling in slowpath"), because direct compation was called only after direct reclaim, which was skipped when PF_MEMALLOC flag was set. Even now it's only a theoretical issue, as the new callsite of __alloc_pages_direct_compact() is reached only for costly orders and when gfp_pfmemalloc_allowed() is true, which means either __GFP_NOMEMALLOC is in gfp_flags or in_interrupt() is true. There is no such known context, but let's play it safe and make __alloc_pages_direct_compact() robust for cases where PF_MEMALLOC is already set. Fixes: a8161d1e ("mm, page_alloc: restructure direct compaction handling in slowpath") Link: http://lkml.kernel.org/r/20170405074700.29871-2-vbabka@suse.czSigned-off-by:

The granularity check to call current_fs_time() or CURRENT_TIME_SEC is not required. Use current_time() directly to update inode timestamp. Use timespec_trunc during file system creation, before the first inode is created. Link: http://lkml.kernel.org/r/1491613030-11599-9-git-send-email-deepa.kernel@gmail.comSigned-off-by:

CURRENT_TIME is not y2038 safe. The macro will be deleted and all the references to it will be replaced by ktime_get_* apis. struct timespec is also not y2038 safe. Retain timespec for timestamp representation here as ceph uses it internally everywhere. These references will be changed to use struct timespec64 in a separate patch. The current_fs_time() api is being changed to use vfs struct inode* as an argument instead of struct super_block*. Set the new mds client request r_stamp field using ktime_get_real_ts() instead of using current_fs_time(). Also, since r_stamp is used as mtime on the server, use timespec_trunc() to truncate the timestamp, using the right granularity from the superblock. This api will be transitioned to be y2038 safe along with vfs. Link: http://lkml.kernel.org/r/1491613030-11599-5-git-send-email-deepa.kernel@gmail.comSigned-off-by:
