2018-03-23crypto: inside-secure - fix clock managementGregory CLEMENT
In this driver the clock is got but never put when the driver is removed or if there is an error in the probe. Using the managed version of clk_get() allows to let the kernel take care of it.

2018-03-23serial: expose buf_overrun count through proc interfaceJeremy Kerr
The buf_overrun count is only every written, and not exposed to userspace anywhere. This means that dropped characters due to flip buffer overruns are never visible to userspace. The /proc/tty/driver/serial file exports a bunch of metrics (including hardware overruns) already, so add the buf_overrun (as "bo:") to this file.

2018-03-23Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/netDavid S. Miller
Fun set of conflict resolutions here... For the mac80211 stuff, these were fortunately just parallel adds. Trivially resolved. In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the function phy_disable_interrupts() earlier in the file, whilst in 'net-next' the phy_error() call from this function was removed. In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the 'rt_table_id' member of rtable collided with a bug fix in 'net' that added a new struct member "rt_mtu_locked" which needs to be copied over here. The mlxsw driver conflict consisted of net-next separating the span code and definitions into separate files, whilst a 'net' bug fix made some changes to that moved code. The mlx5 infiniband conflict resolution was quite non-trivial, the RDMA tree's merge commit was used as a guide here, and here are their notes: ==================== Due to bug fixes found by the syzkaller bot and taken into the for-rc branch after development for the 4.17 merge window had already started being taken into the for-next branch, there were fairly non-trivial merge issues that would need to be resolved between the for-rc branch and the for-next branch. This merge resolves those conflicts and provides a unified base upon which ongoing development for 4.17 can be based. Conflicts: drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524 (IB/mlx5: Fix cleanup order on unload) added to for-rc and commit b5ca15ad7e61 (IB/mlx5: Add proper representors support) add as part of the devel cycle both needed to modify the init/de-init functions used by mlx5. To support the new representors, the new functions added by the cleanup patch needed to be made non-static, and the init/de-init list added by the representors patch needed to be modified to match the init/de-init list changes made by the cleanup patch. Updates: drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function prototypes added by representors patch to reflect new function names as changed by cleanup patch drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init stage list to match new order from cleanup patch ==================== Signed-off-by: David S.

2018-03-23staging: fsl-dpaa2/eth: Change max number of Tx queuesIoana Radulescu
We use DPAA2_ETH_MAX_TX_QUEUES to dimension the array holding information on Tx queues. At most, we can have one queue per cpu. Until now we used the NR_CPUS macro to set the upper limit on number of Tx queues. However, the platforms that the DPAA2 Ethernet driver supports have at most 16 cores, whereas NR_CPUS is Kconfigurable and can be much higher. Avoid allocating memory we'll never use, by setting DPAA2_ETH_MAX_TX_QUEUES to 16. Same for DPAA2_ETH_MAX_DPCONS.
