2018-06-29Revert "i2c: algo-bit: init the bus to a known state"Wolfram Sang
This reverts commit 3e5f06bed72fe72166a6778f630241a893f67799. As per bugzilla #200045, this caused a regression. I don't really see a way to fix it without having the hardware. So, revert the patch and I will fix the issue I was seeing originally in the i2c-gpio driver itself. I couldn't find new users of this algorithm since, so there should be no one depending on the new behaviour.

2018-06-22lightnvm: Remove depends on HAS_DMA in case of platform dependencyGeert Uytterhoeven
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing.

Enabling LPIs was made a lot stricter recently, by checking that they are disabled before enabling them.

2018-06-22irqchip/gic-v3-its: Only emit SYNC if targetting a valid collectionMarc Zyngier
It is possible, under obscure circumstances, to convince the ITS driver to emit a SYNC operation that targets a collection that is not bound to any redistributor (and the target_address field is zero) because the corresponding CPU has not been seen yet (the system has been booted with max_cpus="something small"). If the ITS is using the linear CPU number as the target, this is not a big deal, as we just end-up issuing a SYNC to CPU0. But if the ITS requires the physical address of the redistributor (with GITS_TYPER.PTA==1), we end-up asking the ITS to write to the physical address zero, which is not exactly a good idea (there has been report of the ITS locking up). This should of course never happen, but hey, this is SW... In order to avoid the above disaster, let's track which collections have been actually initialized, and let's not generate a SYNC if the collection hasn't been properly bound to a redistributor. Take this opportunity to spit our a warning, in the hope that someone may report the issue if it arrises again.

2018-06-22irqchip/gic-v3-its: Don't bind LPI to unavailable NUMA nodeYang Yingliang
On a NUMA system, if an ITS is local to an offline node, the ITS driver may pick an offline CPU to bind the LPI. In this case, pick an online CPU (and the first one will do). But on some systems, binding an LPI to non-local node CPU may cause deadlock (see Cavium erratum 23144). In this case, just fail the activate and return an error code.

2018-06-22efi/libstub/tpm: Initialize efi_physical_addr_t vars to zero for mixed modeHans de Goede
Commit: 79832f0b5f71 ("efi/libstub/tpm: Initialize pointer variables to zero for mixed mode") fixes a problem with the tpm code on mixed mode (64-bit kernel on 32-bit UEFI), where 64-bit pointer variables are not fully initialized by the 32-bit EFI code. A similar problem applies to the efi_physical_addr_t variables which are written by the ->get_event_log() EFI call. Even though efi_physical_addr_t is 64-bit everywhere, it seems that some 32-bit UEFI implementations only fill in the lower 32 bits when passed a pointer to an efi_physical_addr_t to fill. This commit initializes these to 0 to, to ensure the upper 32 bits are 0 in mixed mode. This fixes recent kernels sometimes hanging during early boot on mixed mode UEFI systems.

2018-06-22xen: Remove unnecessary BUG_ON from __unbind_from_irq()Boris Ostrovsky
Commit 910f8befdf5b ("xen/pirq: fix error path cleanup when binding MSIs") fixed a couple of errors in error cleanup path of xen_bind_pirq_msi_to_irq(). This cleanup allowed a call to __unbind_from_irq() with an unbound irq, which would result in triggering the BUG_ON there. Since there is really no reason for the BUG_ON (xen_free_irq() can operate on unbound irqs) we can remove it.

2018-06-22xen: add new hypercall buffer mapping deviceJuergen Gross
For passing arbitrary data from user land to the Xen hypervisor the Xen tools today are using mlock()ed buffers. Unfortunately the kernel might change access rights of such buffers for brief periods of time e.g. for page migration or compaction, leading to access faults in the hypervisor, as the hypervisor can't use the locks of the kernel. In order to solve this problem add a new device node to the Xen privcmd driver to easily allocate hypercall buffers via mmap(). The memory is allocated in the kernel and just mapped into user space. Marked as VM_IO the user mapping will not be subject to page migration et al.

2018-06-21nvme-pci: limit max IO size and segments to avoid high order allocationsJens Axboe
nvme requires an sg table allocation for each request. If the request is large, then the allocation can become quite large. For instance, with our default software settings of 1280KB IO size, we'll need 10248 bytes of sg table. That turns into a 2nd order allocation, which we can't always guarantee. If we fail the allocation, blk-mq will retry it later. But there's no guarantee that we'll EVER be able to allocate that much contigious memory. Limit the IO size such that we never need more than a single page of memory. That's a lot faster and more reliable. Then back that allocation with a mempool, so that we know we'll always be able to succeed the allocation at some point.

2018-06-20nvme-rdma: Fix command completion race at error recoveryIsrael Rukshin
The race is between completing the request at error recovery work and rdma completions. If we cancel the request before getting the good rdma completion we get a NULL deref of the request MR at nvme_rdma_process_nvme_rsp(). When Canceling the request we return its mr to the mr pool (set mr to NULL) and also unmap its data. Canceling the requests while the rdma queues are active is not safe. Because rdma queues are active and we get good rdma completions that can use the mr pointer which may be NULL. Completing the request too soon may lead also to performing DMA to/from user buffers which might have been already unmapped. The commit fixes the race by draining the QP before starting the abort commands mechanism.

The HID descriptor for the 2nd-gen Intuos Pro large (PTH-860) contains a typo which defines an incorrect logical maximum Y value. This causes a small portion of the bottom of the tablet to become unusable (both because the area is below the "bottom" of the tablet and because 'wacom_wac_event' ignores out-of-range values). It also results in a skewed aspect ratio. To fix this, we add a quirk to 'wacom_usage_mapping' which overwrites the data with the correct value.

2018-06-20HID: intel_ish-hid: ipc: register more pm callbacks to support hibernationEven Xu
Current ISH driver only registers suspend/resume PM callbacks which don't support hibernation (suspend to disk). Basically after hiberation, the ISH can't resume properly and user may not see sensor events (for example: screen rotation may not work). User will not see a crash or panic or anything except the following message in log: hid-sensor-hub 001F:8086:22D8.0001: timeout waiting for response from ISHTP device So this patch adds support for S4/hiberbation to ISH by using the SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend and resume functions will now be used for both suspend to RAM and hibernation. If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend and resume related functions won't be used, so mark them as __maybe_unused to clarify that this is the intended behavior, and remove #ifdefs for power management.

2018-06-20HID: steam: use hid_device.driver_data instead of hid_set_drvdata()Rodrigo Rivas Costa
When creating the low-level hidraw device, the reference to steam_device was stored using hid_set_drvdata(). But this value is not guaranteed to be kept when set before calling probe. If this pointer is reset, it crashes when opening the emulated hidraw device. It looks like hid_set_drvdata() is for users "avobe" this hid_device, while hid_device.driver_data it for users "below" this one. In this case, we are creating a virtual hidraw device, so we must use hid_device.driver_data.
