      ====================
      Add basic ACPI support to the Qualcomm Technologies EMAC driver
      
      This patch series adds support to the EMAC driver for extracting addresses,
      interrupts, and some _DSDs (properties) from ACPI.  The first two patches
      clean up the code, and the third patch adds ACPI-specific functionality.
      
      The first patch fixes a bug with handling the platform_device for the
      internal PHY.  This phy is treated as a separate device in both DT and
      ACPI, but since the platform is not released automatically when the
      driver unloads, managed functions like devm_ioremap_resource cannot be
      used.
      
      The second patch replaces of_get_mac_address with its platform-independent
      equivalent device_get_mac_address.
      
      The third patch parses the ACPI tables to obtain the platform_device for
      the primary EMAC node ("QCOM8070") and the internal phy node ("QCOM8071").

      net: qcom/emac: initial ACPI support · 5f3d3807
      Timur Tabi authored
      Add support for reading addresses, interrupts, and _DSD properties
      from ACPI tables, just like with device tree.  The HID for the
      EMAC device itself is QCOM8070.  The internal PHY is represented
      by a child node with a HID of QCOM8071.
      
      The EMAC also has some complex clock initialization requirements
      that are not represented by this patch.  This will be addressed
      in a future patch.

      net: qcom/emac: use device_get_mac_address · 0de709ac
      Timur Tabi authored
      Replace the DT-specific of_get_mac_address() function with
      device_get_mac_address, which works on both DT and ACPI platforms.  This
      change makes it easier to add ACPI support.

      net: qcom/emac: do not use devm on internal phy pdev · 54e19bc7
      Timur Tabi authored
      The platform_device returned by of_find_device_by_node() is not
      automatically released when the driver unprobes.  Therefore,
      managed calls like devm_ioremap_resource() should not be used.
      Instead, we manually allocate the resources and then free them
      on driver release.

      bpf: allow access into map value arrays · 48461135
      Josef Bacik authored
      Suppose you have a map array value that is something like this
      
      struct foo {
      	unsigned iter;
      	int array[SOME_CONSTANT];
      };
      
      You can easily insert this into an array, but you cannot modify the contents of
      foo->array[] after the fact.  This is because we have no way to verify we won't
      go off the end of the array at verification time.  This patch provides a start
      for this work.  We accomplish this by keeping track of a minimum and maximum
      value a register could be while we're checking the code.  Then at the time we
      try to do an access into a MAP_VALUE we verify that the maximum offset into that
      region is a valid access into that memory region.  So in practice, code such as
      this
      
      unsigned index = 0;
      
      if (foo->iter >= SOME_CONSTANT)
      	foo->iter = index;
      else
      	index = foo->iter++;
      foo->array[index] = bar;
      
      would be allowed, as we can verify that index will always be between 0 and
      SOME_CONSTANT-1.  If you wish to use signed values you'll have to have an extra
      check to make sure the index isn't less than 0, or do something like index %=
      SOME_CONSTANT.

      Since commit 900f65d3 ("tcp: move duplicate code from
      tcp_v4_init_sock()/tcp_v6_init_sock()") we no longer need
      to export sk_stream_write_space()
