2018-03-14fsi: core: Add check for master property no-scan-on-initChristopher Bostic1-1/+4
Prior to scanning a master check if the optional property no-scan-on-init is present. If it is then avoid scanning. This is necessary in cases where a master scan could interfere with another FSI master on the same bus.

2018-03-14fsi: master: Clarify master lifetimes & fix use-after-free in hub masterJeremy Kerr2-3/+33
Once we call fsi_master_unregister, the core will put_device, potentially freeing the hub master. This change adds a comment explaining the lifetime of an allocated fsi_master. We then add a reference from the driver to the hub master, so it stays around until we've finished ->remove().

2018-03-14fsi: Match fsi slaves and engines to available dt nodesJeremy Kerr4-0/+108
This change populates device tree nodes for scanned FSI slaves and engines. If the master populates ->of_node of the FSI master device, we'll look for matching slaves, and under those slaves we'll look for matching engines. This means that FSI drivers will have their ->of_node pointer populated if there's a corresponding DT node, which they can use for further device discover. Presence of device tree nodes is optional, and only required for fsi device drivers that need extra properties, or subordinate devices, to be enumerated.

2018-03-14dt-bindings: fsi: Add specification for FSI bussesJeremy Kerr1-0/+144
This change introduces a proposed layout for describing FSI busses in the device tree. While the bus is probe-able, we'd still like a method of describing subordinate (eg i2c) busses that are behind FSI devices. The FSI core will be responsible for matching probed slaves & engines to their device tree nodes, so the FSI device drivers' probe() functions will be passed a struct device with the appropriate of_node populated where a matching DT node is found.

2018-03-14fsi: master-gpio: Add external modeJeremy Kerr2-2/+86
This change introduces an 'external mode' for GPIO-based FSI masters, allowing the clock and data lines to be driven by an external source. For example, external mode is selected by a user when an external debug device is attached to the FSI pins. To do this, we need to set specific states for the trans, mux and enable GPIOs, and prevent access to clk & data from the FSI core code (by returning EBUSY). External mode is controlled by a sysfs attribute, so add the relevant information to Documentation/ABI/ Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Reviewed-by: Joel Stanley <joel@jms.id.au> Signed-off-by: Joel Stanley <joel@jms.id.au> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2018-03-06hv_balloon: fix bugs in num_pages_onlined accountingVitaly Kuznetsov1-13/+69
Our num_pages_onlined accounting is buggy: 1) In case we're offlining a memory block which was present at boot (e.g. when there was no hotplug at all) we subtract 32k from 0 and as num_pages_onlined is unsigned get a very big positive number. 2) Commit 6df8d9aaf3af ("Drivers: hv: balloon: Correctly update onlined page count") made num_pages_onlined counter accurate on onlining but totally incorrect on offlining for partly populated regions: no matter how many pages were onlined and what was actually added to num_pages_onlined counter we always subtract the full region (32k) so again, num_pages_onlined can wrap around zero. By onlining/offlining the same partly populated region multiple times we can make the situation worse.

The 2016 version of Hyper-V offers the option to operate the guest VM per-vcpu stimer's in Direct Mode, which means the timer interupts on its own vector rather than queueing a VMbus message. Direct Mode reduces timer processing overhead in both the hypervisor and the guest, and avoids having timer interrupts pollute the VMbus interrupt stream for the synthetic NIC and storage. This patch enables Direct Mode by default on stimer0 when running on a version of Hyper-V that supports it. In prep for coming support of Hyper-V on ARM64, the arch independent portion of the code contains calls to routines that will be populated on ARM64 but are not needed and do nothing on x86.

git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux Pull btrfs fixes from David Sterba: - when NR_CPUS is large, a SRCU structure can significantly inflate size of the main filesystem structure that would not be possible to allocate by kmalloc, so the kvalloc fallback is used - improved error handling - fix endiannes when printing some filesystem attributes via sysfs, this is could happen when a filesystem is moved between different endianity hosts - send fixes: the NO_HOLE mode should not send a write operation for a file hole - fix log replay for for special files followed by file hardlinks - fix log replay failure after unlink and link combination - fix max chunk size calculation for DUP allocation * tag 'for-4.16-rc3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: Btrfs: fix log replay failure after unlink and link combination Btrfs: fix log replay failure after linking special file and fsync Btrfs: send, fix issuing write op when processing hole in no data mode btrfs: use proper endianness accessors for super_copy btrfs: alloc_chunk: fix DUP stripe size handling btrfs: Handle btrfs_set_extent_delalloc failure in relocate_file_extent_cluster btrfs: handle failure of add_pending_csums btrfs: use kvzalloc to allocate btrfs_fs_info

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm fixes from Dan Williams: "A 4.16 regression fix, three fixes for -stable, and a cleanup fix: - During the merge window support for the new ACPI NVDIMM Platform Capabilities structure disabled support for "deep flush", a force-unit- access like mechanism for persistent memory. Restore that mechanism. - VFIO like RDMA is yet one more memory registration / pinning interface that is incompatible with Filesystem-DAX. Disable long term pins of Filesystem-DAX mappings via VFIO. - The Filesystem-DAX detection to prevent long terms pins mistakenly also disabled Device-DAX pins which are not subject to the same block- map collision concerns. - Similar to the setup path, softlockup warnings can trigger in the shutdown path for large persistent memory namespaces. Teach for_each_device_pfn() to perform cond_resched() in all cases. - Boaz noticed that the might_sleep() in dax_direct_access() is stale as of the v4.15 kernel. These have received a build success notification from the 0day robot, and the longterm pin fixes have appeared in -next. However, I recently rebased the tree to remove some other fixes that need to be reworked after review feedback. * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: memremap: fix softlockup reports at teardown libnvdimm: re-enable deep flush for pmem devices via fsync() vfio: disable filesystem-dax page pinning dax: fix vma_is_fsdax() helper dax: ->direct_access does not sleep anymore
