2017-02-10l2tp: do not use udp_ioctl()Eric Dumazet
udp_ioctl(), as its name suggests, is used by UDP protocols, but is also used by L2TP :( L2TP should use its own handler, because it really does not look the same. SIOCINQ for instance should not assume UDP checksum or headers. Thanks to Andrey and syzkaller team for providing the report and a nice reproducer.

2017-02-10NET: mkiss: Fix panicRalf Baechle
If a USB-to-serial adapter is unplugged, the driver re-initializes, with dev->hard_header_len and dev->addr_len set to zero, instead of the correct values. If then a packet is sent through the half-dead interface, the kernel will panic due to running out of headroom in the skb when pushing for the AX.25 headers resulting in this panic: [<c0595468>] (skb_panic) from [<c0401f70>] (skb_push+0x4c/0x50) [<c0401f70>] (skb_push) from [<bf0bdad4>] (ax25_hard_header+0x34/0xf4 [ax25]) [<bf0bdad4>] (ax25_hard_header [ax25]) from [<bf0d05d4>] (ax_header+0x38/0x40 [mkiss]) [<bf0d05d4>] (ax_header [mkiss]) from [<c041b584>] (neigh_compat_output+0x8c/0xd8) [<c041b584>] (neigh_compat_output) from [<c043e7a8>] (ip_finish_output+0x2a0/0x914) [<c043e7a8>] (ip_finish_output) from [<c043f948>] (ip_output+0xd8/0xf0) [<c043f948>] (ip_output) from [<c043f04c>] (ip_local_out_sk+0x44/0x48) This patch makes mkiss behave like the 6pack driver. 6pack does not panic.

2017-02-10mtd: spi-nor: add a stateless method to support memory size above 128MibCyrille Pitchen
This patch provides an alternative mean to support memory above 16MiB (128Mib) by replacing 3byte address op codes by their associated 4byte address versions. Using the dedicated 4byte address op codes doesn't change the internal state of the SPI NOR memory as opposed to using other means such as updating a Base Address Register (BAR) and sending command to enter/leave the 4byte mode. Hence when a CPU reset occurs, early bootloaders don't need to be aware of BAR value or 4byte mode being enabled: they can still access the first 16MiB of the SPI NOR memory using the regular 3byte address op codes.

The patch also introduces new op codes to support other SPI protocols such as SPI 1-4-4 and SPI 1-2-2. This is a transitional patch and will help a later patch of spi-nor.c to automate the translation from the 3-byte address op codes into their 4-byte address version.

CE2 can be of NOR type flash but this is not supported by the driver * SPI Flash Controller (SPI1 and SPI2) . host firmware . 2 chip select pins (CE0 ~ CE1) . supports SPI type flash memory Each controller has a memory range on which it maps its flash module slaves. Each slave is assigned a memory window for its mapping that can be changed at bootime with the Segment Address Register. Each SPI flash slave can then be accessed in two modes: Command and User. When in User mode, accesses to the memory segment of the slaves are translated in SPI transfers. When in Command mode, the HW generates the SPI commands automatically and the memory segment is accessed as if doing a MMIO. Currently, only the User mode is supported. Command mode needs a little more work to check that the memory window on the AHB bus fits the module size. Based on previous work from Milton D.

2017-02-10iommu: Rename struct iommu_deviceJoerg Roedel
The struct is used to link devices to iommu-groups, so 'struct group_device' is a better name. Further this makes the name iommu_device available for a struct representing hardware iommus. Signed-off-by: Joerg Roedel <jroedel@suse.de>
2017-02-10iommu: Rename iommu_get_instance()Joerg Roedel
Rename the function to iommu_ops_from_fwnode(), because that is what the function actually does. The new name is much more descriptive about what the function does. Signed-off-by: Joerg Roedel <jroedel@suse.de>
