2016-11-10ARM: dts: stih407-clocks: Identify critical clocksPeter Griffin
Lots of platforms contain clocks which if turned off would prove fatal. The only way to recover is to restart the board(s). This driver takes references to clocks which are required to be always-on. The Common Clk Framework will then take references to them. This way they will not be turned off during the clk_disabled_unused() procedure. In this patch we are identifying clocks, which if gated would render the STiH407 development board unserviceable.

2016-10-20ARM: dts: stih410-clocks: Add PROC_STFE as a critical clockPeter Griffin
Once the ST frontend demux HW IP has been enabled, the clock can't be disabled otherwise the system will hang and the board will be unserviceable. To allow balanced clock enable/disable calls in the driver we use the critical clock infrastructure to take an extra reference on the clock so the clock will never actually be disabled.

2016-10-14fs/super.c: fix race between freeze_super() and thaw_super()Oleg Nesterov
Change thaw_super() to check frozen != SB_FREEZE_COMPLETE rather than frozen == SB_UNFROZEN, otherwise it can race with freeze_super() which drops sb->s_umount after SB_FREEZE_WRITE to preserve the lock ordering. In this case thaw_super() will wrongly call s_op->unfreeze_fs() before it was actually frozen, and call sb_freeze_unlock() which leads to the unbalanced percpu_up_write(). Unfortunately lockdep can't detect this, so this triggers misc BUG_ON()'s in kernel/rcu/sync.c.

2016-10-14overlayfs: Fix setting IOP_XATTR flagVivek Goyal
ovl_fill_super calls ovl_new_inode to create a root inode for the new superblock before initializing sb->s_xattr. This wrongly causes IOP_XATTR to be cleared in i_opflags of the new inode, causing SELinux to log the following message: SELinux: (dev overlay, type overlay) has no xattr support Fix this by initializing sb->s_xattr and similar fields before calling ovl_new_inode.

2016-10-14iov_iter: kernel-doc import_iovec() and rw_copy_check_uvector()Vegard Nossum
Both import_iovec() and rw_copy_check_uvector() take an array (typically small and on-stack) which is used to hold an iovec array copy from userspace. This is to avoid an expensive memory allocation in the fast path (i.e. few iovec elements). The caller may have to check whether these functions actually used the provided buffer or allocated a new one -- but this differs between the too. Let's just add a kernel doc to clarify what the semantics are for each function. Signed-off-by: Vegard Nossum <vegard.nossum@oracle.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma qedr RoCE driver from Doug Ledford: "Early on in the merge window I mentioned I had a backlog of new drivers waiting to be reviewed and that, in addition to the hns-roce driver, I wanted to get possible a couple more reviewed. I ended up only having the time to complete one of the additional drivers. During Dave Miller's pull request this go around, there were a series of 9 patches to the QLogic qed net driver that add basic support for a paired RoCE driver. That support is currently not functional because it is missing the matching RoCE driver in the RDMA subsystem. I managed to finish that review. However, because it goes against part of Dave's net pull, and a part that was accepted a day or two after the merge window opened, to apply cleanly it has to be applied to either the tip of Dave's net branch, or as I did in this case, I just applied it to your master after you had taken Dave's pull request." * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: qedr: Add events support and register IB device qedr: Add GSI support qedr: Add LL2 RoCE interface qedr: Add support for data path qedr: Add support for memory registeration verbs qedr: Add support for QP verbs qedr: Add support for PD,PKEY and CQ verbs qedr: Add support for user context verbs qedr: Add support for RoCE HW init qedr: Add RoCE driver framework
