      Introduce CONFIG_HAS_DMA · 411f0f3e
      Heiko Carstens 提交于
      Architectures that don't support DMA can say so by adding a config NO_DMA
      to their Kconfig file.  This will prevent compilation of some dma specific
      driver code.  Also dma-mapping-broken.h isn't needed anymore on at least
      s390.  This avoids compilation and linking of otherwise dead/broken code.
      
      Other architectures that include dma-mapping-broken.h are arm26, h8300,
      m68k, m68knommu and v850.  If these could be converted as well we could get
      rid of the header file.

      [S390]: Fix build on 31-bit. · cb8c181f
      David S. Miller 提交于
      Allow s390 to properly override the generic
      __div64_32() implementation by:
      
      1) Using obj-y for div64.o in s390's makefile instead
         of lib-y
      
      2) Adding the weak attribute to the generic implementation.

      [NET]: Inline net_device_stats · c45d286e
      Rusty Russell 提交于
      Network drivers which keep stats allocate their own stats structure
      then write a get_stats() function to return them.  It would be nice if
      this were done by default.
      
      1) Add a new "stats" field to "struct net_device".
      2) Add a new feature field to say "this driver uses the internal one"
      3) Have a default "get_stats" which returns NULL if that feature not set.
      4) Change callers to check result of get_stats call for NULL, not if
         ->get_stats is set.
      
      This should not break backwards compatibility with older drivers, yet
      allow modern drivers to shed some boilerplate code.
      
      Lightly tested: works for a modified lguest network driver.

      [S390] kprobes: Align probe address. · b70842df
      David Wilder 提交于
      Running a probe on s390 with a probe address that is not 4 byte aligned
      results in a Kernel BUG.  The problem is that the stura instruction used
      by swap_instruction requires the destination address to be 4 byte aligned.
      As stura only writes 4 bytes, aligning to the next 4 byte aligned address
      results in the breakpoint instruction being stored past the probe address.
      The fix is to align the address backward (to the previous 4 byte aligned
      address) and writing the two byte breakpoint instruction in the appropriate
      bytes.
