      mei: Avoid the use of one-element arrays · 3c3b7dde
      Gustavo A. R. Silva authored
      One-element arrays are being deprecated[1]. Replace the one-element
      arrays with a simple value type u8 reserved, once this is just a
      placeholder for alignment.
      
      Also, while there, use the preferred form for passing a size of a struct.
      The alternative form where struct name is spelled out hurts readability
      and introduces an opportunity for a bug when the variable type is changed
      but the corresponding sizeof that is passed as argument is not.

      mei: Replace HTTP links with HTTPS ones · 74b04fae
      Alexander A. Klimov authored
      Rationale:
      Reduces attack surface on kernel devs opening the links for MITM
      as HTTPS traffic is much harder to manipulate.
      
      Deterministic algorithm:
      For each file:
        If not .svg:
          For each line:
            If doesn't contain `\bxmlns\b`:
              For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
      	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
                  If both the HTTP and HTTPS versions
                  return 200 OK and serve the same content:
                    Replace HTTP with HTTPS.

      mei: hdcp: Replace one-element array with flexible-array member · c56967d6
      Gustavo A. R. Silva authored
      There is a regular need in the kernel to provide a way to declare
      having a dynamically sized set of trailing elements in a structure.
      Kernel code should always use “flexible array members”[1] for these
      cases. The older style of one-element or zero-length arrays should
      no longer be used[2].
      
      Also, make use of the array_size() helper instead of the open-coded
      version in memcpy(). These sorts of multiplication factors need to
      be wrapped in array_size().
      
      And while there, use the preferred form for passing a size of a struct.
      The alternative form where struct name is spelled out hurts readability
      and introduces an opportunity for a bug when the pointer variable type is
      changed but the corresponding sizeof that is passed as argument is not.

      FPGA Manager changes for 5.9-rc1
      
      Here is the (slightly larger than usual) patch set for the 5.9-rc1 merge
      window.
      
      DFL:
      - Xu's changes add support for AFU interrupt handling and puts them to
        use for error handling.
      - Xu's other change also adds another device-id for the Intel FPGA PAC N3000.
      - John's change converts from using get_user_pages() to
        pin_user_pages().
      - Gustavo's patch cleans up some of the allocation by using
        struct_size().
      
      Xilinx:
      - Luca's changes clean up the xilinx-spi and xilinx-slave-serial drivers
        and updates the comments and dt-bindings to reflect the fact it also
        supports 7 series devices.
      
      Core:
      - Tom cleaned up the fpga-bridge / fpga-mgr core by removing some
        dead-stores.
      
      All patches have been reviewed on the mailing list, and have been in the
      last few linux-next releases (as part of my for-next branch) without issues.

      Pull x86 fixes from Thomas Gleixner:
       "A pile of fixes for x86:
      
         - Fix the I/O bitmap invalidation on XEN PV, which was overlooked in
           the recent ioperm/iopl rework. This caused the TSS and XEN's I/O
           bitmap to get out of sync.
      
         - Use the proper vectors for HYPERV.
      
         - Make disabling of stack protector for the entry code work with GCC
           builds which enable stack protector by default. Removing the option
           is not sufficient, it needs an explicit -fno-stack-protector to
           shut it off.
      
         - Mark check_user_regs() noinstr as it is called from noinstr code.
           The missing annotation causes it to be placed in the text section
           which makes it instrumentable.
      
         - Add the missing interrupt disable in exc_alignment_check()
      
         - Fixup a XEN_PV build dependency in the 32bit entry code
      
         - A few fixes to make the Clang integrated assembler happy
      
         - Move EFI stub build to the right place for out of tree builds
      
         - Make prepare_exit_to_usermode() static. It's not longer called from
           ASM code"
