We need to make sure that the error code from devm_of_pwm_get() is the one the module returns in case of failure. Restructure the code to make this possible for DT booted case. With this patch the driver can ask for deferred probing when the board is booted with DT. Fixes for example omap4-sdp board's keyboard backlight led.

In commit 7314e613 ("Fix a few incorrectly checked [io_]remap_pfn_range() calls") the uio driver started more properly checking the passed-in user mapping arguments against the size of the actual uio driver data. That in turn exposed that some driver authors apparently didn't realize that mmap can only work on a page granularity, and had tried to use it with smaller mappings, with the new size check catching that out. So since it's not just the user mmap() arguments that can be confused, make the uio mmap code also verify that the uio driver has the memory allocated at page boundaries in order for mmap to work. If the device memory isn't properly aligned, we return [ENODEV] The fildes argument refers to a file whose type is not supported by mmap(). as per the open group documentation on mmap.

Pull networking updates from David Miller: "Here is a pile of bug fixes that accumulated while I was in Europe" 1) In fixing kernel leaks to userspace during copying of socket addresses, we broke a case that used to work, namely the user providing a buffer larger than the in-kernel generic socket address structure. This broke Ruby amongst other things. Fix from Dan Carpenter. 2) Fix regression added by byte queue limit support in 8139cp driver, from Yang Yingliang. 3) The addition of MSG_SENDPAGE_NOTLAST buggered up a few sendpage implementations, they should just treat it the same as MSG_MORE. Fix from Richard Weinberger and Shawn Landden. 4) Handle icmpv4 errors received on ipv6 SIT tunnels correctly, from Oussama Ghorbel.

The pipe code was trying (and failing) to be very careful about freeing the pipe info only after the last access, with a pattern like: spin_lock(&inode->i_lock); if (!--pipe->files) { inode->i_pipe = NULL; kill = 1; } spin_unlock(&inode->i_lock); __pipe_unlock(pipe); if (kill) free_pipe_info(pipe); where the final freeing is done last. HOWEVER. The above is actually broken, because while the freeing is done at the end, if we have two racing processes releasing the pipe inode info, the one that *doesn't* free it will decrement the ->files count, and unlock the inode i_lock, but then still use the "pipe_inode_info" afterwards when it does the "__pipe_unlock(pipe)". This is *very* hard to trigger in practice, since the race window is very small, and adding debug options seems to just hide it by slowing things down. Simon originally reported this way back in July as an Oops in kmem_cache_allocate due to a single bit corruption (due to the final "spin_unlock(pipe->mutex.wait_lock)" incrementing a field in a different allocation that had re-used the free'd pipe-info), it's taken this long to figure out. Since the 'pipe->files' accesses aren't even protected by the pipe lock (we very much use the inode lock for that), the simple solution is to just drop the pipe lock early. And since there were two users of this pattern, create a helper function for it. Introduced commit ba5bb147 ("pipe: take allocation and freeing of pipe_inode_info out of ->i_mutex").

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to igb, e1000 and ixgbe. Akeem provides a igb fix where WOL was being reported as supported on some ethernet devices which did not have that capability. Yanjun provides a fix for e1000 which is similar to a previous fix for e1000e commit bb9e44d0 ("e1000e: prevent oops when adapter is being closed and reset simultaneously"), where the same issue was observed on the older e1000 cards. Vladimir Davydov provides 2 e1000 fixes. The first fixes a lockdep warning e1000_down() tries to synchronously cancel e1000 auxiliary works (reset_task, watchdog_task, phy_info_task and fifo_stall_task) which take adapter->mutex in their handlers. The second patch is to fix a possible race condition where reset_task() would be running after adapter down. John provides 2 fixes for ixgbe. First turns ixgbe_fwd_ring_down to static and the second disables NETIF_F_HW_L2FW_DOFFLOAD by default because it allows upper layer net devices to use queues in the hardware to directly submit and receive skbs. Mark Rustad provides a single patch for ixgbe to make ixgbe_identify_qsfp_module_generic static to resolve compile warnings. v2: Drop igb patch "igb: Update queue reinit function to call dev_close when init of queues fails" from Carolyn, so that the solution can be re-worked based on feedback from David Miller. ==================== Signed-off-by: NDavid S.

NETIF_F_HW_L2FW_DOFFLOAD allows upper layer net devices such as macvlan to use queues in the hardware to directly submit and receive skbs. This creates a subtle change in the datapath though. One change being the skb may no longer use the root devices qdisc. Because users may not expect this we can't enable the feature by default unless the hardware can offload all the software functionality above it. So for now disable it by default and let users opt in.
