      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"

      Pull timer fixes from Thomas Gleixner:
       "Two fixes for the timer wheel:
      
         - A timer which is already expired at enqueue time can set the
           base->next_expiry value backwards. As a consequence base->clk can
           be set back as well. This can lead to timers expiring early. Add a
           sanity check to prevent this.
      
         - When a timer is queued with an expiry time beyond the wheel
           capacity then it should be queued in the bucket of the last wheel
           level which is expiring last.
      
           The code adjusted the expiry time to the maximum wheel capacity,
           which is only correct when the wheel clock is 0. Aside of that the
           check whether the delta is larger than wheel capacity does not
           check the delta, it checks the expiry value itself. As a result
           timers can expire at random.
      
           Fix this by checking the right variable and adjust expiry time so
           it becomes base->clock plus capacity which places it into the
           outmost bucket in the last wheel level"
