      sysctl: Remove the sysctl system call · 61a47c1a
      Eric W. Biederman 提交于
      This system call has been deprecated almost since it was introduced, and
      in a survey of the linux distributions I can no longer find any of them
      that enable CONFIG_SYSCTL_SYSCALL.  The only indication that I can find
      that anyone might care is that a few of the defconfigs in the kernel
      enable CONFIG_SYSCTL_SYSCALL.  However this appears in only 31 of 414
      defconfigs in the kernel, so I suspect this symbols presence is simply
      because it is harmless to include rather than because it is necessary.
      
      As there appear to be no users of the sysctl system call, remove the
      code.  As this removes one of the few uses of the internal kernel mount
      of proc I hope this allows for even more simplifications of the proc
      filesystem.

      dma-direct: provide mmap and get_sgtable method overrides · 34dc0ea6
      Christoph Hellwig 提交于
      For dma-direct we know that the DMA address is an encoding of the
      physical address that we can trivially decode.  Use that fact to
      provide implementations that do not need the arch_dma_coherent_to_pfn
      architecture hook.  Note that we still can only support mmap of
      non-coherent memory only if the architecture provides a way to set an
      uncached bit in the page tables.  This must be true for architectures
      that use the generic remap helpers, but other architectures can also
      manually select it.
