The code refactoring by commit 0176adb0 ("swiotlb: refactor coherent buffer allocation") made swiotlb_alloc_buffer almost always failing due to a thinko: namely, the function evaluates the dma_coherent_ok call incorrectly and dealing as if it's invalid. This ends up with weird errors like iwlwifi probe failure or amdgpu screen flickering. This patch corrects the logic error.

Pull ceph updates from Ilya Dryomov: "The big ticket items are: - support for rbd "fancy" striping (myself). The striping feature bit is now fully implemented, allowing mapping v2 images with non-default striping patterns. This completes support for --image-format 2. - CephFS quota support (Luis Henriques and Zheng Yan). This set is based on the new SnapRealm code in the upcoming v13.y.z ("Mimic") release. Quota handling will be rejected on older filesystems. - memory usage improvements in CephFS (Chengguang Xu). Directory specific bits have been split out of ceph_file_info and some effort went into improving cap reservation code to avoid OOM crashes. Also included a bunch of assorted fixes all over the place from Chengguang and others" * tag 'ceph-for-4.17-rc1' of git://github.com/ceph/ceph-client: (67 commits) ceph: quota: report root dir quota usage in statfs ceph: quota: add counter for snaprealms with quota ceph: quota: cache inode pointer in ceph_snap_realm ceph: fix root quota realm check ceph: don't check quota for snap inode ceph: quota: update MDS when max_bytes is approaching ceph: quota: support for ceph.quota.max_bytes ceph: quota: don't allow cross-quota renames ceph: quota: support for ceph.quota.max_files ceph: quota: add initial infrastructure to support cephfs quotas rbd: remove VLA usage rbd: fix spelling mistake: "reregisteration" -> "reregistration" ceph: rename function drop_leases() to a more descriptive name ceph: fix invalid point dereference for error case in mdsc destroy ceph: return proper bool type to caller instead of pointer ceph: optimize memory usage ceph: optimize mds session register libceph, ceph: add __init attribution to init funcitons ceph: filter out used flags when printing unused open flags ceph: don't wait on writeback when there is no more dirty pages ...

Pull libnvdimm updates from Dan Williams: "This cycle was was not something I ever want to repeat as there were several late changes that have only now just settled. Half of the branch up to commit d2c997c0 ("fs, dax: use page->mapping to warn...") have been in -next for several releases. The of_pmem driver and the address range scrub rework were late arrivals, and the dax work was scaled back at the last moment. The of_pmem driver missed a previous merge window due to an oversight. A sense of obligation to rectify that miss is why it is included for 4.17. It has acks from PowerPC folks. Stephen reported a build failure that only occurs when merging it with your latest tree, for now I have fixed that up by disabling modular builds of of_pmem. A test merge with your tree has received a build success report from the 0day robot over 156 configs. An initial version of the ARS rework was submitted before the merge window. It is self contained to libnvdimm, a net code reduction, and passing all unit tests. The filesystem-dax changes are based on the wait_var_event() functionality from tip/sched/core. However, late review feedback showed that those changes regressed truncate performance to a large degree. The branch was rewound to drop the truncate behavior change and now only includes preparation patches and cleanups (with full acks and reviews). The finalization of this dax-dma-vs-trnucate work will need to wait for 4.18. Summary: - A rework of the filesytem-dax implementation provides for detection of unmap operations (truncate / hole punch) colliding with in-progress device-DMA. A fix for these collisions remains a work-in-progress pending resolution of truncate latency and starvation regressions. - The of_pmem driver expands the users of libnvdimm outside of x86 and ACPI to describe an implementation of persistent memory on PowerPC with Open Firmware / Device tree. - Address Range Scrub (ARS) handling is completely rewritten to account for the fact that ARS may run for 100s of seconds and there is no platform defined way to cancel it. ARS will now no longer block namespace initialization. - The NVDIMM Namespace Label implementation is updated to handle label areas as small as 1K, down from 128K. - Miscellaneous cleanups and updates to unit test infrastructure" * tag 'libnvdimm-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (39 commits) libnvdimm, of_pmem: workaround OF_NUMA=n build error nfit, address-range-scrub: add module option to skip initial ars nfit, address-range-scrub: rework and simplify ARS state machine nfit, address-range-scrub: determine one platform max_ars value powerpc/powernv: Create platform devs for nvdimm buses doc/devicetree: Persistent memory region bindings libnvdimm: Add device-tree based driver libnvdimm: Add of_node to region and bus descriptors libnvdimm, region: quiet region probe libnvdimm, namespace: use a safe lookup for dimm device name libnvdimm, dimm: fix dpa reservation vs uninitialized label area libnvdimm, testing: update the default smart ctrl_temperature libnvdimm, testing: Add emulation for smart injection commands nfit, address-range-scrub: introduce nfit_spa->ars_state libnvdimm: add an api to cast a 'struct nd_region' to its 'struct device' nfit, address-range-scrub: fix scrub in-progress reporting dax, dm: allow device-mapper to operate without dax support dax: introduce CONFIG_DAX_DRIVER fs, dax: use page->mapping to warn if truncate collides with a busy page ext2, dax: introduce ext2_dax_aops ...

Pull media fixes from Mauro Carvalho Chehab: "A series of media updates/fixes for 4.17. There are two important core fix patches in this series: - A regression fix on Kernel 4.16 with causes it to not work with some input devices that depend on media core - A fix at compat32 bits with causes it to OOPS on overlay, and affects the Kernels where the CVE-2017-13166 was backported The remaining ones are other random fixes at the documentation and on drivers. The biggest part of this series is a set of 18 patches for the Intel atomisp driver. Currently, it produces hundreds of warnings/errors on sparse/smatch, causing me to sometimes ignore new warnings on other drivers that are not so broken. This driver is on really poor state, even for staging standards: it has several layers of abstraction on it, and it supports two different hardware. Selecting between them require to add a define (there isn't even a Kconfig option for such purpose). Just on this smatch cleanup, I could easily get rid of 8 "do-nothing" files. So, I'm seriously considering its removal from upstream, if I don't see any real work on addressing the problems there along this year" * tag 'media/v4.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (48 commits) media: v4l2-core: fix size of devnode_nums[] bitarray media: v4l2-compat-ioctl32: don't oops on overlay media: i2c: adv748x: afe: fix sparse warning media: extended-controls.rst: transmitter -> receiver media: staging: atomisp: stop duplicating input format types media: staging: atomisp: get rid of an unused var media: staging: atomisp: stop mixing enum types media: staging: atomisp: get rid of some static warnings media: staging: atomisp: use %p to print pointers media: staging: atomisp: remove an useless check media: staging: atomisp: avoid a warning if 32 bits build media: staging: atomisp: don't access a NULL var media: staging: atomisp: Get rid of *default.host.[ch] media: staging: atomisp: get rid of an unused function media: staging: atomisp: remove unused set_pd_base() media: staging: atomisp: fix endianess issues media: staging: atomisp: add a missing include media: staging: atomisp: get rid of stupid statements media: staging: atomisp: declare static vars as such media: staging: atomisp: ia_css_output.host: don't use var before check ...

c6x depends on the macro '_BIG_ENDIAN' being defined or not to correctly select or define endian-specific macros, structures or pieces of code. This macro is predefined by the compiler but sparse knows nothing about it and thus may pre-process files differently from what gcc would. Fix this by passing '-D_BIG_ENDIAN' when compiling a big-endian kernel, like GCC would have done.

Commit 0619f0f5 ("selinux: wrap selinuxfs state") triggers a BUG when SELinux is runtime-disabled (i.e. systemd or equivalent disables SELinux before initial policy load via /sys/fs/selinux/disable based on /etc/selinux/config SELINUX=disabled). This does not manifest if SELinux is disabled via kernel command line argument or if SELinux is enabled (permissive or enforcing). Before: SELinux: Disabled at runtime. BUG: Dentry 000000006d77e5c7{i=17,n=null} still in use (1) [unmount of selinuxfs selinuxfs] After: SELinux: Disabled at runtime.

Commit 3c8ba0d6 ("kernel.h: Retain constant expression output for max()/min()") rewrote our min/max macros to be very clever, but in the meantime resurrected a variable name shadow issue that we had had previously fixed in commit 589a9785 ("min/max: remove sparse warnings when they're nested"). That commit talks about the sparse warnings that this shadowing causes, which we ignored as just a minor annoyance. But it turns out that the sparse warning is the least of our problems. We actually have a real bug due to the shadowing through the interaction with "min_not_zero()", which ends up doing min(__x, __y) internally, and then the new declaration of "__x" and "__y" as new variables in __cmp_once() results in a complete mess of an expression, and "min_not_zero()" doesn't work at all. For some odd reason, this only ever caused (reported) problems on s390, even though it is a generic issue and most of the (obviously successful) testing of the problematic commit had happened on other architectures. Quoting Sebastian Ott: "What happened is that the bio build by the partition detection code was attempted to be split by the block layer because the block queue had a max_sector setting of 0. blk_queue_max_hw_sectors uses min_not_zero." So re-introduce the use of __UNIQUE_ID() to make sure that the min/max macros do not have these kinds of clashes. [ That said, __UNIQUE_ID() itself has several issues that make it less than wonderful. In particular, the "uniqueness" has a fallback on the line number, which means that it's not actually unique in more complex cases if you don't build with gcc or clang (which have working unique counters that aren't tied to line numbers). That historical broken fallback also means that we have that pointless "prefix" argument that doesn't actually make much sense _except_ for the known-broken case. Oh well. ] Fixes: 3c8ba0d6 ("kernel.h: Retain constant expression output for max()/min()") Reported-and-tested-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Cc: Kees Cook <keescook@chromium.org> Cc: Ingo Molnar <mingo@kernel.org> Cc: Miguel Ojeda <miguel.ojeda.sandonis@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
