+Subject: ACPI: scan: Create platform device for CS35L56
+
+From: Simon Trimmer <simont@opensource.cirrus.com>
+
+commit 1cd0302be5645420f73090aee26fa787287e1096 upstream.
+
+The ACPI device CSC3556 is a Cirrus Logic CS35L56 mono amplifier which
+is used in multiples, and can be connected either to I2C or SPI.
+
+There will be multiple instances under the same Device() node. Add it
+to ignore_serial_bus_ids and handle it in the serial-multi-instantiate
+driver.
+
+There can be a 5th I2cSerialBusV2, but this is an alias address and doesn't
+represent a real device. Ignore this by having a dummy 5th entry in the
+serial-multi-instantiate instance list with the name of a non-existent
+driver, on the same pattern as done for bsg2150.

+From: Masahiro Yamada <masahiroy@kernel.org>
+
+commit 6ccbd7fd474674654019a20177c943359469103a upstream.
+
+EXPORT_SYMBOL and __init is a bad combination because the .init.text
+section is freed up after the initialization.
+
+Commit c5a130325f13 ("ACPI/APEI: Add parameter check before error

+be removed.
+
+This fixes the modpost warning in ARCH=alpha builds:

+Subject: platform/x86: serial-multi-instantiate: Auto detect IRQ resource for CSC3551
+
+From: David Xu <xuwd1@hotmail.com>
+
+commit 676b7c5ecab36274442887ceadd6dee8248a244f upstream.
+
+The current code assumes that the CSC3551(multiple cs35l41) always have
+its interrupt pin connected to GPIO thus the IRQ can be acquired with
+acpi_dev_gpio_irq_get. However on some newer laptop models this is no
+longer the case as they have the CSC3551's interrupt pin connected to
+APIC. This causes smi_i2c_probe to fail on these machines.
+
+To support these machines, a new macro IRQ_RESOURCE_AUTO was introduced
+for cs35l41 smi_node, and smi_get_irq function was modified so it tries
+to get GPIO irq resource first and if failed, tries to get
+APIC irq resource for cs35l41.
+
+This patch affects only the cs35l41's probing and brings no negative
+influence on machines that indeed have the cs35l41's interrupt pin
+connected to GPIO.

+Subject: sch_netem: fix issues in netem_change() vs get_dist_table()
+
+From: Eric Dumazet <edumazet@google.com>
+
+commit 11b73313c12403f617b47752db0ab3deef201af7 upstream.
+
+In blamed commit, I missed that get_dist_table() was allocating
+memory using GFP_KERNEL, and acquiring qdisc lock to perform
+the swap of newly allocated table with current one.
+
+In this patch, get_dist_table() is allocating memory and
+copy user data before we acquire the qdisc lock.
+
+Then we perform swap operations while being protected by the lock.
+
+Note that after this patch netem_change() no longer can do partial changes.
+If an error is returned, qdisc conf is left unchanged.
+
+Fixes: 2174a08db80d ("sch_netem: acquire qdisc lock in netem_change()")

+Subject: scsi: core: Fix legacy /proc parsing buffer overflow
+
+From: Tony Battersby <tonyb@cybernetics.com>
+
+commit 9426d3cef5000824e5f24f80ed5f42fb935f2488 upstream.
+
+(lightly modified commit message mostly by Linus Torvalds)
+
+The parsing code for /proc/scsi/scsi is disgusting and broken. We should
+have just used 'sscanf()' or something simple like that, but the logic may
+actually predate our kernel sscanf library routine for all I know. It
+certainly predates both git and BK histories.
+
+And we can't change it to be something sane like that now, because the
+string matching at the start is done case-insensitively, and the separator
+parsing between numbers isn't done at all, so *any* separator will work,
+including a possible terminating NUL character.
+
+This interface is root-only, and entirely for legacy use, so there is
+absolutely no point in trying to tighten up the parsing. Because any
+separator has traditionally worked, it's entirely possible that people have
+used random characters rather than the suggested space.
+
+So don't bother to try to pretty it up, and let's just make a minimal patch
+that can be back-ported and we can forget about this whole sorry thing for
+another two decades.
+
+Just make it at least not read past the end of the supplied data.

+If device_add() returns error, the name allocated by dev_set_name() needs

+Subject: scsi: fnic: Replace return codes in fnic_clean_pending_aborts()
+
+From: Karan Tilak Kumar <kartilak@cisco.com>
+
+commit 5a43b07a87835660f91d88a4db11abfea8c523b7 upstream.
+
+fnic_clean_pending_aborts() was returning a non-zero value irrespective of
+failure or success. This caused the caller of this function to assume that
+the device reset had failed, even though it would succeed in most cases. As
+a consequence, a successful device reset would escalate to host reset.

+
+From: Nilesh Javali <njavali@marvell.com>
+
+commit ef222f551e7c4e2008fc442ffc9edcd1a7fd8f63 upstream.
+
+While performing certain power-off sequences, PCI drivers are called to
+suspend and resume their underlying devices through PCI PM (power
+management) interface. However the hardware does not support PCI PM
+suspend/resume operations so system wide suspend/resume leads to bad MFW
+(management firmware) state which causes various follow-up errors in driver
+when communicating with the device/firmware.
+
+To fix this driver implements PCI PM suspend handler to indicate
+unsupported operation to the PCI subsystem explicitly, thus avoiding system
+to go into suspended/standby mode.

+If device_add() returns error, the name allocated by dev_set_name() needs

+Subject: scsi: storvsc: Fix handling of virtual Fibre Channel timeouts
+
+From: Michael Kelley <mikelley@microsoft.com>
+
+commit 175544ad48cbf56affeef2a679c6a4d4fb1e2881 upstream.
+
+Hyper-V provides the ability to connect Fibre Channel LUNs to the host
+system and present them in a guest VM as a SCSI device. I/O to the vFC
+device is handled by the storvsc driver. The storvsc driver includes a
+partial integration with the FC transport implemented in the generic
+portion of the Linux SCSI subsystem so that FC attributes can be displayed
+in /sys. However, the partial integration means that some aspects of vFC
+don't work properly. Unfortunately, a full and correct integration isn't
+practical because of limitations in what Hyper-V provides to the guest.
+
+In particular, in the context of Hyper-V storvsc, the FC transport timeout
+function fc_eh_timed_out() causes a kernel panic because it can't find the
+rport and dereferences a NULL pointer. The original patch that added the
+call from storvsc_eh_timed_out() to fc_eh_timed_out() is faulty in this
+regard.
+
+In many cases a timeout is due to a transient condition, so the situation
+can be improved by just continuing to wait like with other I/O requests
+issued by storvsc, and avoiding the guaranteed panic. For a permanent
+failure, continuing to wait may result in a hung thread instead of a panic,
+which again may be better.
+
+So fix the panic by removing the storvsc call to fc_eh_timed_out(). This
+allows storvsc to keep waiting for a response. The change has been tested
+by users who experienced a panic in fc_eh_timed_out() due to transient
+timeouts, and it solves their problem.
+
+In the future we may want to deprecate the vFC functionality in storvsc
+since it can't be fully fixed. But it has current users for whom it is
+working well enough, so it should probably stay for a while longer.
+
