+Subject: bnx2x: Improve reliability in case of nested PCI errors
+
+From: "Guilherme G. Piccoli" <gpiccoli@linux.vnet.ibm.com>
+
+
+[ Upstream commit f7084059a9cb9e56a186e1677b1dcffd76c2cd24 ]
+
+While in recovery process of PCI error (called EEH on PowerPC arch),
+another PCI transaction could be corrupted causing a situation of
+nested PCI errors. Also, this scenario could be reproduced with
+error injection mechanisms (for debug purposes).
+
+We observe that in case of nested PCI errors, bnx2x might attempt to
+initialize its shmem and cause a kernel crash due to bad addresses
+read from MCP. Multiple different stack traces were observed depending
+on the point the second PCI error happens.
+
+This patch avoids the crashes by:
+
+ * failing PCI recovery in case of nested errors (since multiple
+ PCI errors in a row are not expected to lead to a functional
+ adapter anyway), and by,
+
+ * preventing access to adapter FW when MCP is failed (we mark it as
+ failed when shmem cannot get initialized properly).

+
+From: Brendan McGrath <redmcg@redmandi.dyndns.org>
+
+
+[ Upstream commit 588753f1eb18978512b1c9b85fddb457d46f9033 ]
+
+One example of when an ICMPv6 packet is required to be looped back is
+when a host acts as both a Multicast Listener and a Multicast Router.
+
+A Multicast Router will listen on address ff02::16 for MLDv2 messages.
+
+Currently, MLDv2 messages originating from a Multicast Listener running
+on the same host as the Multicast Router are not being delivered to the
+Multicast Router. This is due to dst.input being assigned the default
+value of dst_discard.
+
+This results in the packet being looped back but discarded before being
+delivered to the Multicast Router.
+
+This patch sets dst.input to ip6_input to ensure a looped back packet
+is delivered to the Multicast Router.

+Subject: mtd: nand: gpmi: Fix failure when a erased page has a bitflip at BBM
+
+From: Sascha Hauer <s.hauer@pengutronix.de>
+
+
+[ Upstream commit fdf2e821052958a114618a95ab18a300d0b080cb ]
+
+When erased subpages are read then the BCH decoder returns STATUS_ERASED
+if they are all empty, or STATUS_UNCORRECTABLE if there are bitflips.
+When there are bitflips, we have to set these bits again to show the
+upper layers a completely erased page. When a bitflip happens in the
+exact byte where the bad block marker is, then this byte is swapped
+with another byte in block_mark_swapping(). The correction code then
+detects a bitflip in another subpage and no longer corrects the bitflip
+where it really happens.
+
+Correct this behaviour by calling block_mark_swapping() after the
+bitflips have been corrected.
+
+In our case UBIFS failed with this bug because it expects erased
+pages to be really empty:
+
+UBIFS error (pid 187): ubifs_scan: corrupt empty space at LEB 36:118735
+UBIFS error (pid 187): ubifs_scanned_corruption: corruption at LEB 36:118735

+In case dma_map_single() failure previously allocated skb became

+
+From: Stefan Haberland <sth@linux.vnet.ibm.com>
+
+
+[ Upstream commit 8a9bd4f8ebc6800bfc0596e28631ff6809a2f615 ]
+
+We store per path and per device configuration data to identify the
+path or device correctly. The per path configuration data might get
+mixed up if the original request gets into error recovery and is
+started with a random path mask.
+
+This would lead to a wrong identification of a path in case of a CUIR
+event for example.
+
+Fix by copying the path mask from the original request to the error
+recovery request in case it is a path verification request.

+From: Cathy Avery <cavery@redhat.com>
+
+
+[ Upstream commit d1b8b2391c24751e44f618fcf86fb55d9a9247fd ]
+
+When an I/O is returned with an srb_status of SRB_STATUS_INVALID_LUN
+which has zero good_bytes it must be assigned an error. Otherwise the
+I/O will be continuously requeued and will cause a deadlock in the case
+where disks are being hot added and removed. sd_probe_async will wait
+forever for its I/O to complete while holding scsi_sd_probe_domain.
+
+Also returning the default error of DID_TARGET_FAILURE causes multipath
+to not retry the I/O resulting in applications receiving I/O errors
+before a failover can occur.

+
+
+[ Upstream commit c76f97c99ae6d26d14c7f0e50e074382bfbc9f98 ]
+
+Some sockopt handling functions were calculating the length of the
+buffer to be written to userspace and then calculating it again when
+actually writing the buffer, which could lead to some write not using
+an up-to-date length.
+
+This patch updates such places to just make use of the len variable.
+
+Also, replace some sizeof(type) to sizeof(var).

+[ Upstream commit 66e900a3d225575c8b48b59ae1fe74bb6e5a65cc ]
+
+The only part of atmel_spi_remove which needs to be atomic is hardware
+reset.
+
+atmel_spi_stop_dma calls dma_terminate_all and this needs interrupts
+enabled.
+atmel_spi_release_dma calls dma_release_channel and dma_release_channel
+locks a mutex inside of spin_lock.
+
+So the call of these functions can't be inside a spin_lock.

+A customer noticed RX path hang when MTU is changed on the fly while
+running heavy traffic with NCSI enabled for 5717 and 5719. Since 5720
+belongs to same ASIC family, we observed same issue and same fix
+could solve this problem for 5720.

+
+When cleaning up after a partially successful gntdev_mmap(), unmap the

+in debug mode (Attempt to implicitly unmap a granted PTE) or Linux will
+kill the process and emit "BUG: Bad page map in process" if Xen is in

+
+This is only needed when use_ptemod is true because gntdev_put_map()

+Subject: xen-netfront: enable device after manual module load
+
+From: Eduardo Otubo <otubo@redhat.com>
+
+
+[ Upstream commit b707fda2df4070785d0fa8a278aa13944c5f51f8 ]
+
+When loading the module after unloading it, the network interface would
+not be enabled and thus wouldn't have a backend counterpart and unable
+to be used by the guest.
+
+The guest would face errors like:
+
+ [root@guest ~]# ethtool -i eth0
+ Cannot get driver information: No such device
+
+ [root@guest ~]# ifconfig eth0
+ eth0: error fetching interface information: Device not found
+
+This patch initializes the state of the netfront device whenever it is
+loaded manually, this state would communicate the netback to create its
+device and establish the connection between them.
