      Pull tracing fixes from Steven Rostedt:
       "Two more small fixes.
      
        One is by Yang Shi who added a READ_ONCE_NOCHECK() to the scan of the
        stack made by the stack tracer.  As the stack tracer scans the entire
        kernel stack, KASAN triggers seeing it as a "stack out of bounds"
        error.  As the scan is looking at the contents of the stack from
        parent functions.  The NOCHECK() tells KASAN that this is done on
        purpose, and is not some kind of stack overflow.
      
        The second fix is to the ftrace selftests, to retrieve the PID of
        executed commands from the shell with '$!' and not by parsing 'jobs'"

      Pull rdma fixes from Doug Ledford:
       "One ocrdma fix:
      
         - The new CQ API support was added to ocrdma, but they got the arming
           logic wrong, so without this, transfers eventually fail when they
           fail to arm the interrupt properly under load
      
        Two related fixes for mlx4:
      
         - When we added the 64bit extended counters support to the core IB
           code, they forgot to update the RoCE side of the mlx4 driver (the
           IB side they properly updated).
      
           I debated whether or not to include these patches as they could be
           considered feature enablement patches, but the existing code will
           blindy copy the 32bit counters, whether any counters were requested
           at all (a bug).
      
           These two patches make it (a) check to see that counters were
           requested and (b) copy the right counters (the 64bit support is
           new, the 32bit is not).  For that reason I went ahead and took
           them"

      net: ethernet: davicom: fix devicetree irq resource · b5a099c6
      Robert Jarzmik authored
      The dm9000 driver doesn't work in at least one device-tree
      configuration, spitting an error message on irq resource :
      [    1.062495] dm9000 8000000.ethernet: insufficient resources
      [    1.068439] dm9000 8000000.ethernet: not found (-2).
      [    1.073451] dm9000: probe of 8000000.ethernet failed with error -2
      
      The reason behind is that the interrupt might be provided by a gpio
      controller, not probed when dm9000 is probed, and needing the probe
      deferral mechanism to apply.
      
      Currently, the interrupt is directly taken from resources. This patch
      changes this to use the more generic platform_get_irq(), which handles
      the deferral.
      
      Moreover, since commit Fixes: 7085a740 ("drivers: platform: parse
      IRQ flags from resources"), the interrupt trigger flags are honored in
      platform_get_irq(), so remove the needless code in dm9000.

      net: ti: netcp: restore get/set_pad_info() functionality · 9ecfe875
      Karicheri, Muralidharan authored
      The commit 89907779 ("netcp: try to reduce type confusion in
      descriptors") introduces a regression in Kernel 4.5-rc1 and it breaks
      get/set_pad_info() functionality.
      
      The TI NETCP driver uses pad0 and pad1 fields of knav_dma_desc to
      store DMA/MEM buffer pointer and buffer size respectively. And in both
      cases for Keystone 2 the pointer type size is 32 bit regardless of
      LAPE enabled or not, because CONFIG_ARCH_DMA_ADDR_T_64BIT originally
      is not expected to be defined.
      
      Unfortunately, above commit changed buffer's pointers save/restore
      code (get/set_pad_info()) and added intermediate conversation to u64
      which works incorrectly on 32bit Keystone 2 and causes TI NETCP driver
      crash in RX/TX path due to "Unable to handle kernel NULL pointer"
      exception. This issue was reported and discussed in [1].
      
      Hence, fix it by partially reverting above commit and restoring
      get/set_pad_info() functionality as it was before.

      sctp: Fix port hash table size computation · d9749fb5
      Neil Horman authored
      Dmitry Vyukov noted recently that the sctp_port_hashtable had an error in
      its size computation, observing that the current method never guaranteed
      that the hashsize (measured in number of entries) would be a power of two,
      which the input hash function for that table requires.  The root cause of
      the problem is that two values need to be computed (one, the allocation
      order of the storage requries, as passed to __get_free_pages, and two the
      number of entries for the hash table).  Both need to be ^2, but for
      different reasons, and the existing code is simply computing one order
      value, and using it as the basis for both, which is wrong (i.e. it assumes
      that ((1<<order)*PAGE_SIZE)/sizeof(bucket) is still ^2 when its not).
      
      To fix this, we change the logic slightly.  We start by computing a goal
      allocation order (which is limited by the maximum size hash table we want
      to support.  Then we attempt to allocate that size table, decreasing the
      order until a successful allocation is made.  Then, with the resultant
      successful order we compute the number of buckets that hash table supports,
      which we then round down to the nearest power of two, giving us the number
      of entries the table actually supports.
      
      I've tested this locally here, using non-debug and spinlock-debug kernels,
      and the number of entries in the hashtable consistently work out to be
      powers of two in all cases.

      kernel/resource.c: fix muxed resource handling in __request_region() · 59ceeaaf
      Simon Guinot authored
      In __request_region, if a conflict with a BUSY and MUXED resource is
      detected, then the caller goes to sleep and waits for the resource to be
      released.  A pointer on the conflicting resource is kept.  At wake-up
      this pointer is used as a parent to retry to request the region.
      
      A first problem is that this pointer might well be invalid (if for
      example the conflicting resource have already been freed).  Another
      problem is that the next call to __request_region() fails to detect a
      remaining conflict.  The previously conflicting resource is passed as a
      parameter and __request_region() will look for a conflict among the
      children of this resource and not at the resource itself.  It is likely
      to succeed anyway, even if there is still a conflict.
      
      Instead, the parent of the conflicting resource should be passed to
      __request_region().
      
      As a fix, this patch doesn't update the parent resource pointer in the
      case we have to wait for a muxed region right after.

      Bluetooth: hci_core: Avoid mixing up req_complete and req_complete_skb · 3bd7594e
      Douglas Anderson authored
      In commit 44d27137 ("Bluetooth: Compress the size of struct
      hci_ctrl") we squashed down the size of the structure by using a union
      with the assumption that all users would use the flag to determine
      whether we had a req_complete or a req_complete_skb.
      
      Unfortunately we had a case in hci_req_cmd_complete() where we weren't
      looking at the flag.  This can result in a situation where we might be
      storing a hci_req_complete_skb_t in a hci_req_complete_t variable, or
      vice versa.
      
      During some testing I found at least one case where the function
      hci_req_sync_complete() was called improperly because the kernel thought
      that it didn't require an SKB.  Looking through the stack in kgdb I
      found that it was called by hci_event_packet() and that
      hci_event_packet() had both of its locals "req_complete" and
      "req_complete_skb" pointing to the same place: both to
      hci_req_sync_complete().
      
      Let's make sure we always check the flag.
      
      For more details on debugging done, see <http://crbug.com/588288>.

      net: bcmgenet: Fix internal PHY link state · d07c0278

      The internal PHY should use phy_mac_interrupt() when not in use
      PHY_POLL. The statement for phy_mac_interrupt() has two conditions. The
      first condition to check GENET_HAS_MDIO_INTR is not related PHY link
      state, so this patch removes it.

      af_unix: Don't use continue to re-execute unix_stream_read_generic loop · 18eceb81
      Rainer Weikusat authored
      The unix_stream_read_generic function tries to use a continue statement
      to restart the receive loop after waiting for a message. This may not
      work as intended as the caller might use a recvmsg call to peek at
      control messages without specifying a message buffer. If this was the
      case, the continue will cause the function to return without an error
      and without the credential information if the function had to wait for a
      message while it had returned with the credentials otherwise. Change to
      using goto to restart the loop without checking the condition first in
      this case so that credentials are returned either way.

      unix_diag: fix incorrect sign extension in unix_lookup_by_ino · b5f05492

      However, when ino is compared with sock_i_ino return value of type
      unsigned long, ino is sign extended to signed long, and this results
      to incorrect comparison on 64-bit architectures for inode numbers
      greater than INT_MAX.
