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! :-).

2017-05-08lustre: replace CURRENT_TIME macroDeepa Dinamani
CURRENT_TIME macro is not y2038 safe on 32 bit systems. The patch replaces all the uses of CURRENT_TIME by current_time() for filesystem times, and ktime_get_* functions for others. struct timespec is also not y2038 safe. Retain timespec for timestamp representation here as lustre uses it internally everywhere. These references will be changed to use struct timespec64 in a separate patch. This is also in preparation for the patch that transitions vfs timestamps to use 64 bit time and hence make them y2038 safe. current_time() is also planned to be transitioned to y2038 safe behavior along with this change. CURRENT_TIME macro will be deleted before merging the aforementioned change.

2017-05-08fs: ceph: CURRENT_TIME with ktime_get_real_ts()Deepa Dinamani
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.

2017-05-08format-security: move static strings to constKees Cook
While examining output from trial builds with -Wformat-security enabled, many strings were found that should be defined as "const", or as a char array instead of char pointer. This makes some static analysis easier, by producing fewer false positives. As these are all trivial changes, it seemed best to put them all in a single patch rather than chopping them up per maintainer.

2017-05-08mm, vmalloc: use __GFP_HIGHMEM implicitlyMichal Hocko
__vmalloc* allows users to provide gfp flags for the underlying allocation. This API is quite popular $ git grep "=[[:space:]]__vmalloc\|return[[:space:]]*__vmalloc" | wc -l 77 The only problem is that many people are not aware that they really want to give __GFP_HIGHMEM along with other flags because there is really no reason to consume precious lowmemory on CONFIG_HIGHMEM systems for pages which are mapped to the kernel vmalloc space. About half of users don't use this flag, though. This signals that we make the API unnecessarily too complex. This patch simply uses __GFP_HIGHMEM implicitly when allocating pages to be mapped to the vmalloc space. Current users which add __GFP_HIGHMEM are simplified and drop the flag.

2017-05-08treewide: use kv[mz]alloc* rather than opencoded variantsMichal Hocko
There are many code paths opencoding kvmalloc. Let's use the helper instead. The main difference to kvmalloc is that those users are usually not considering all the aspects of the memory allocator. E.g. allocation requests <= 32kB (with 4kB pages) are basically never failing and invoke OOM killer to satisfy the allocation. This sounds too disruptive for something that has a reasonable fallback - the vmalloc. On the other hand those requests might fallback to vmalloc even when the memory allocator would succeed after several more reclaim/compaction attempts previously. There is no guarantee something like that happens though. This patch converts many of those places to kv[mz]alloc* helpers because they are more conservative.

2017-05-08mm: support __GFP_REPEAT in kvmalloc_node for >32kBMichal Hocko
vhost code uses __GFP_REPEAT when allocating vhost_virtqueue resp. vhost_vsock because it would really like to prefer kmalloc to the vmalloc fallback - see 23cc5a991c7a ("vhost-net: extend device allocation to vmalloc") for more context. Michael Tsirkin has also noted: "__GFP_REPEAT overhead is during allocation time. Using vmalloc means all accesses are slowed down. Allocation is not on data path, accesses are." The similar applies to other vhost_kvzalloc users. Let's teach kvmalloc_node to handle __GFP_REPEAT properly. There are two things to be careful about. First we should prevent from the OOM killer and so have to involve __GFP_NORETRY by default and secondly override __GFP_REPEAT for !costly order requests as the __GFP_REPEAT is ignored for !costly orders. Supporting __GFP_REPEAT like semantic for !costly request is possible it would require changes in the page allocator. This is out of scope of this patch. This patch shouldn't introduce any functional change.

2017-05-08mm: introduce kv[mz]alloc helpersMichal Hocko
Patch series "kvmalloc", v5. There are many open coded kmalloc with vmalloc fallback instances in the tree. Most of them are not careful enough or simply do not care about the underlying semantic of the kmalloc/page allocator which means that a) some vmalloc fallbacks are basically unreachable because the kmalloc part will keep retrying until it succeeds b) the page allocator can invoke a really disruptive steps like the OOM killer to move forward which doesn't sound appropriate when we consider that the vmalloc fallback is available. As it can be seen implementing kvmalloc requires quite an intimate knowledge if the page allocator and the memory reclaim internals which strongly suggests that a helper should be implemented in the memory subsystem proper. Most callers, I could find, have been converted to use the helper instead. This is patch 6. There are some more relying on __GFP_REPEAT in the networking stack which I have converted as well and Eric Dumazet was not opposed [2] to convert them as well. [1] http://lkml.kernel.org/r/20170130094940.13546-1-mhocko@kernel.org [2] http://lkml.kernel.org/r/1485273626.16328.301.camel@edumazet-glaptop3.roam.corp.google.com This patch (of 9): Using kmalloc with the vmalloc fallback for larger allocations is a common pattern in the kernel code. Yet we do not have any common helper for that and so users have invented their own helpers. Some of them are really creative when doing so. Let's just add kv[mz]alloc and make sure it is implemented properly. This implementation makes sure to not make a large memory pressure for > PAGE_SZE requests (__GFP_NORETRY) and also to not warn about allocation failures. This also rules out the OOM killer as the vmalloc is a more approapriate fallback than a disruptive user visible action. This patch also changes some existing users and removes helpers which are specific for them. In some cases this is not possible (e.g. ext4_kvmalloc, libcfs_kvzalloc) because those seems to be broken and require GFP_NO{FS,IO} context which is not vmalloc compatible in general (note that the page table allocation is GFP_KERNEL). Those need to be fixed separately. While we are at it, document that __vmalloc{_node} about unsupported gfp mask because there seems to be a lot of confusion out there. kvmalloc_node will warn about GFP_KERNEL incompatible (which are not superset) flags to catch new abusers. Existing ones would have to die slowly.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "The bulk of this has been in multiple -next releases. There were a few late breaking fixes and small features that got added in the last couple days, but the whole set has received a build success notification from the kbuild robot. Change summary: - Region media error reporting: A libnvdimm region device is the parent to one or more namespaces. To date, media errors have been reported via the "badblocks" attribute attached to pmem block devices for namespaces in "raw" or "memory" mode. Given that namespaces can be in "device-dax" or "btt-sector" mode this new interface reports media errors generically, i.e. independent of namespace modes or state. This subsequently allows userspace tooling to craft "ACPI 6.1 Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error" requests and submit them via the ioctl path for NVDIMM root bus devices. - Introduce 'struct dax_device' and 'struct dax_operations': Prompted by a request from Linus and feedback from Christoph this allows for dax capable drivers to publish their own custom dax operations. This fixes the broken assumption that all dax operations are related to a persistent memory device, and makes it easier for other architectures and platforms to add customized persistent memory support. - 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is available for storage appliance applications to manually trigger memory controllers to drain write-pending buffers that would otherwise be flushed automatically by the platform ADR (asynchronous-DRAM-refresh) mechanism at a power loss event.

It's a big one, adding about 350k new lines of crap^Wcode, mostly all in a big dump of media drivers from Intel. But there's other new drivers in here as well, yet-another-wifi driver, new IIO drivers, and a new crypto accelerator. We also deleted a bunch of stuff, mostly in patch cleanups, but also the Android ION code has shrunk a lot, and the Android low memory killer driver was finally deleted, much to the celebration of the -mm developers.

By default we use a 128TB virtual address space, but a process can request access to the full 512TB by passing a hint to mmap(). - Support for the new Power9 "XIVE" interrupt controller. - TLB flushing optimisations for the radix MMU on Power9. - Support for CAPI cards on Power9, using the "Coherent Accelerator Interface Architecture 2.0". - The ability to configure the mmap randomisation limits at build and runtime. - Several small fixes and cleanups to the kprobes code, as well as support for KPROBES_ON_FTRACE. - Major improvements to handling of system reset interrupts, correctly treating them as NMIs, giving them a dedicated stack and using a new hypervisor call to trigger them, all of which should aid debugging and robustness. - Many fixes and other minor enhancements.

This leads to cases where there is enough capacity reserved to hold all the allocated sections, but vmemmap_populate_hugepages() still encounters -ENOMEM from altmap_alloc_block_buf(). This fix is a stop-gap until we can teach the core memory hotplug implementation to permit sub-section hotplug.
