2016-01-09libnvdimm: don't fail init for full badblocks listDan Williams
If the badblocks list runs out of space it simply means that software is unable to intercept all errors. This is no different than the latent discovery of new badblocks case and should not be an initialization failure condition. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

2016-01-09libnvdimm: Add a poison list and export badblocksVishal Verma
During region creation, perform Address Range Scrubs (ARS) for the SPA (System Physical Address) ranges to retrieve known poison locations from firmware. Add a new data structure 'nd_poison' which is used as a list in nvdimm_bus to store these poison locations. When creating a pmem namespace, if there is any known poison associated with its physical address space, convert the poison ranges to bad sectors that are exposed using the badblocks interface.

2016-01-08drivers/tty/serial: delete unused MODULE_DEVICE_TABLE from atmel_serial.cPaul Gortmaker
In commit c39dfebc7798956fd2140ae6321786ff35da30c3 ("drivers/tty/serial: make serial/atmel_serial.c explicitly non-modular") we removed the code relating to modular support since it currently only supports built in. However, when redoing my build coverage for mips allmodconfig, which sets CONFIG_OF, I noticed a remaining line that needs to be removed, else we will get a build failure for an undefined module macro. Unfortunately this didn't appear for any of the other arch I tested more frequently, such as ARM. Since MODULE_DEVICE_TABLE is a no-op for non-modular code, we can just remove the offending line.

2016-01-08dm snapshot: fix hung bios when copy error occursMikulas Patocka
When there is an error copying a chunk dm-snapshot can incorrectly hold associated bios indefinitely, resulting in hung IO. The function copy_callback sets pe->error if there was error copying the chunk, and then calls complete_exception. complete_exception calls pending_complete on error, otherwise it calls commit_exception with commit_callback (and commit_callback calls complete_exception). The persistent exception store (dm-snap-persistent.c) assumes that calls to prepare_exception and commit_exception are paired. persistent_prepare_exception increases ps->pending_count and persistent_commit_exception decreases it. If there is a copy error, persistent_prepare_exception is called but persistent_commit_exception is not. This results in the variable ps->pending_count never returning to zero and that causes some pending exceptions (and their associated bios) to be held forever. Fix this by unconditionally calling commit_exception regardless of whether the copy was successful. A new "valid" parameter is added to commit_exception -- when the copy fails this parameter is set to zero so that the chunk that failed to copy (and all following chunks) is not recorded in the snapshot store. Also, remove commit_callback now that it is merely a wrapper around pending_complete.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2016-01-08 This series contains updates to ixgbe only. Vasu provides three fixes for ixgbe, first assigns a minimum credit to a traffic class to resolve a Tx hang for CEE mode configuration. Second fix changes the driver to use netdev->fcoe_ddp_xid instead of our local IXGBE_FCOE_DDP_MAX, since it is correctly set for our different devices and avoids a DDP skip error on X550. Lastly fix the PFC configuration to include X550 devices. Emil provides a fix for reporting the speed in ethtool by using the stored value in out adapter structure. This is due to external drivers may end up with unknown speed when calling ethtool_get_settings(). Mark fixes the handling of any outer UDP checksum, by passing the skb up with CHECKSUM_NONE when an outer UDP checksum is set. This will cause the stack to check the checksum, also do not increment an error counter because we do not really know if there is an actual error. Ixgbe ATR was not handling IPv6 extended headers, so ATR is not being performed on such packets. Fix this by skipping extended headers when they are present. Usha fixes an issue with X550 and getting FDMI HBA attributes when FCoE support is enabled. Neerav fixes an issue for X550 when FCoE and SR-IOV are enabled, which the hardware generates MDD events. Resolve this by setting the expected values in the transmit context descriptors for FCoE/FIP frames and adding a flush after writing the RDLEN register. ==================== Signed-off-by: David S.
