      efi/fdt: Avoid FDT manipulation after ExitBootServices() · c8f325a5
      Ard Biesheuvel authored
      Some AArch64 UEFI implementations disable the MMU in ExitBootServices(),
      after which unaligned accesses to RAM are no longer supported.
      
      Commit:
      
        abfb7b68 ("efi/libstub/arm*: Pass latest memory map to the kernel")
      
      fixed an issue in the memory map handling of the stub FDT code, but
      inadvertently created an issue with such firmware, by moving some
      of the FDT manipulation to after the invocation of ExitBootServices().
      
      Given that the stub's libfdt implementation uses the ordinary, accelerated
      string functions, which rely on hardware handling of unaligned accesses,
      manipulating the FDT with the MMU off may result in alignment faults.
      
      So fix the situation by moving the update_fdt_memmap() call into the
      callback function invoked by efi_exit_boot_services() right before it
      calls the ExitBootServices() UEFI service (which is arguably a better
      place for it anyway)
      
      Note that disabling the MMU in ExitBootServices() is not compliant with
      the UEFI spec, and carries great risk due to the fact that switching from
      cached to uncached memory accesses halfway through compiler generated code
      (i.e., involving a stack) can never be done in a way that is architecturally
      safe.

      Pull networking fixes from David Miller:
      
       1) Fix handling of interrupt status in stmmac driver. Just because we
          have masked the event from generating interrupts, doesn't mean the
          bit won't still be set in the interrupt status register. From Alexey
          Brodkin.
      
       2) Fix DMA API debugging splats in gianfar driver, from Arseny Solokha.
      
       3) Fix off-by-one error in __ip6_append_data(), from Vlad Yasevich.
      
       4) cls_flow does not match on icmpv6 codes properly, from Simon Horman.
      
       5) Initial MAC address can be set incorrectly in some scenerios, from
          Ivan Vecera.
      
       6) Packet header pointer arithmetic fix in ip6_tnl_parse_tlv_end_lim(),
          from Dan Carpenter.
      
       7) Fix divide by zero in __tcp_select_window(), from Eric Dumazet.
      
       8) Fix crash in iwlwifi when unregistering thermal zone, from Jens
          Axboe.

          Khoroshilov.
