      dmaengine: hsu: Fix memory leak when stopping a running transfer · 42977082
      Peter Ujfalusi 提交于
      The vd->node is removed from the lists when the transfer started so the
      vchan_get_all_descriptors() will not find it. This results memory leak.

      x86/asm/irq: Stop relying on magic JMP behavior for early_idt_handlers · 425be567
      Andy Lutomirski 提交于
      The early_idt_handlers asm code generates an array of entry
      points spaced nine bytes apart.  It's not really clear from that
      code or from the places that reference it what's going on, and
      the code only works in the first place because GAS never
      generates two-byte JMP instructions when jumping to global
      labels.
      
      Clean up the code to generate the correct array stride (member size)
      explicitly. This should be considerably more robust against
      screw-ups, as GAS will warn if a .fill directive has a negative
      count.  Using '. =' to advance would have been even more robust
      (it would generate an actual error if it tried to move
      backwards), but it would pad with nulls, confusing anyone who
      tries to disassemble the code.  The new scheme should be much
      clearer to future readers.
      
      While we're at it, improve the comments and rename the array and
      common code.
      
      Binutils may start relaxing jumps to non-weak labels.  If so,
      this change will fix our build, and we may need to backport this
      change.

      Revert "iommu/amd: Don't allocate with __GFP_ZERO in alloc_coherent" · 2d0ec7a1
      Joerg Roedel 提交于
      This reverts commit 5fc872c7.
      
      The DMA-API does not strictly require that the memory
      returned by dma_alloc_coherent is zeroed out. For that
      another function (dma_zalloc_coherent) should be used. But
      all other x86 DMA-API implementation I checked zero out the
      memory, so that some drivers rely on it and break when it is
      not.
      
      It seems the (driver-)world is not yet ready for this
      change, so revert it.
