2019-09-07platform/x86: intel_int0002_vgpio: Fix wakeups not working on Cherry TrailHans de Goede
Commit 871f1f2bcb01 ("platform/x86: intel_int0002_vgpio: Only implement irq_set_wake on Bay Trail") removed the irq_set_wake method from the struct irq_chip used on Cherry Trail, but it did not set IRQCHIP_SKIP_SET_WAKE causing kernel/irq/manage.c: set_irq_wake_real() to return -ENXIO. This causes the kernel to no longer see PME events reported through the INT0002 device as wakeup events. Which e.g. breaks wakeup by the (USB) keyboard on many Cherry Trail 2-in-1 devices.

2019-07-30platform/x86: asus-wmi: fix CPU fan control on recent productsDaniel Drake
Previously, asus-wmi was using the AGFN interface and FAN_CTRL device for CPU fan control. However, this code has been found to be not fully working on some recent products, and having checked the spec, these interfaces are marked as being removed from future products currently in development. The replacement appears to be the CPU_FAN device, added in spec version 8.3 (March 2014) and present on many modern Asus laptops. Add support for this device, and use it whenever it is detected. The older approach based on AGFN and FAN_CTRL is used as a fallback on products that do not have such device. Other than switching between automatic and full speed, there is no fan speed control through this new interface.

2019-07-30platform/x86: asus-wmi: cleanup AGFN fan handlingDaniel Drake
The asus-wmi driver currently uses the "AGFN" interface and the FAN_CTRL device for fan control. According to the spec, this interface is very dated and marked as pending removal from products currently in development. Clean up the way that the AGFN fan is detected and handled, also preparing the driver for the introduction of an alternate fan control method needed to support recent Asus products. Not anticipating further development of this interface, simplify the code by dropping any notion of being able to control multiple AGFN fans (this was already limited to just a single fan through only exposing a single fan in sysfs). Check for the presence of AGFN fans at probe time, simplifying the code flow in asus_hwmon_sysfs_is_visible().

2019-07-21iommu/amd: fix a crash in iova_magazine_free_pfnsQian Cai
The commit b3aa14f02254 ("iommu: remove the mapping_error dma_map_ops method") incorrectly changed the checking from dma_ops_alloc_iova() in map_sg() causes a crash under memory pressure as dma_ops_alloc_iova() never return DMA_MAPPING_ERROR on failure but 0, so the error handling is all wrong. kernel BUG at drivers/iommu/iova.c:801!

2019-07-21hexagon: switch to generic version of pte allocationMike Rapoport
The hexagon implementation pte_alloc_one(), pte_alloc_one_kernel(), pte_free_kernel() and pte_free() is identical to the generic except of lack of __GFP_ACCOUNT for the user PTEs allocation. Switch hexagon to use generic version of these functions. Signed-off-by: Mike Rapoport <rppt@linux.ibm.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
