      i2c-core: Fix for lockdep validator · 390946b1
      Jean Delvare authored
      If kernel is compiled with CONFIG_PROVE_LOCKING the
      validator raises an error when a multiplexer is removed
      via sysfs and sub-clients are connected to it. This is a
      false positive.
      Documentation/lockdep-design.txt recommends to handle this
      via calls to mutex_lock_nested().
      
      Based on an earlier fix from Michael Lawnick.
      
      Note that the extra code resolves to nothing unless
      CONFIG_DEBUG_LOCK_ALLOC=y.

      i2c-designware: Fix build error if CONFIG_I2C_DESIGNWARE_PLATFORM=y && CONFIG_I2C_DESIGNWARE_PCI=y · e68bb91b
      Axel Lin authored
      This patch adds config I2C_DESIGNWARE_CORE in Kconfig, and let
      I2C_DESIGNWARE_PLATFORM and I2C_DESIGNWARE_PCI select I2C_DESIGNWARE_CORE.
      
      Because both I2C_DESIGNWARE_PLATFORM and I2C_DESIGNWARE_PCI can be built as
      built-in or module, we also need to export the functions in i2c-designware-core.
      
      This fixes below build error when CONFIG_I2C_DESIGNWARE_PLATFORM=y &&
      CONFIG_I2C_DESIGNWARE_PCI=y:

       "Another set of fixes for ARM dma-mapping subsystem.
      
        Commit e9da6e99 replaced custom consistent buffer remapping code
        with generic vmalloc areas.  It however introduced some regressions
        caused by limited support for allocations in atomic context.  This
        series contains fixes for those regressions.
      
        For some subplatforms the default, pre-allocated pool for atomic
        allocations turned out to be too small, so a function for setting its
        size has been added.
      
        Another set of patches adds support for atomic allocations to
        IOMMU-aware DMA-mapping implementation.
      
        The last part of this pull request contains two fixes for Contiguous
        Memory Allocator, which relax too strict requirements."

      xen/pciback: Fix proper FLR steps. · 80ba77df
      Konrad Rzeszutek Wilk authored
      When we do FLR and save PCI config we did it in the wrong order.
      The end result was that if a PCI device was unbind from
      its driver, then binded to xen-pciback, and then back to its
      driver we would get:

      This fixes it by first saving the PCI configuration space, then
      doing the FLR.

      Fix order of arguments to compat_put_time[spec|val] · ed6fe9d6
      Mikulas Patocka authored
      Commit 644595f8 ("compat: Handle COMPAT_USE_64BIT_TIME in
      net/socket.c") introduced a bug where the helper functions to take
      either a 64-bit or compat time[spec|val] got the arguments in the wrong
      order, passing the kernel stack pointer off as a user pointer (and vice
      versa).
      
      Because of the user address range check, that in turn then causes an
      EFAULT due to the user pointer range checking failing for the kernel
      address.  Incorrectly resuling in a failed system call for 32-bit
      processes with a 64-bit kernel.
      
      On odder architectures like HP-PA (with separate user/kernel address
      spaces), it can be used read kernel memory.

      drm: use drm_compat_ioctl for 32-bit apps · 804d74ab
      Keith Packard authored
      Most of the DRM drivers appear to be missing the .compat_ioctl file
      operation entry necessary for 32-bit application compatibility.
      
      This patch  uses drm_compat_ioctl for all drivers which don't have
      their own, and which are using drm_ioctl for .unlocked_ioctl.
      
      This leaves drivers/gpu/drm/psb/psb_drv.c unchanged; it has a custom
      .unlocked_ioctl and will presumably need a custom .compat_ioctl as
      well.

      xen: Use correct masking in xen_swiotlb_alloc_coherent. · b5031ed1
      Ronny Hegewald authored
      When running 32-bit pvops-dom0 and a driver tries to allocate a coherent
      DMA-memory the xen swiotlb-implementation returned memory beyond 4GB.
      
      The underlaying reason is that if the supplied driver passes in a
      DMA_BIT_MASK(64) ( hwdev->coherent_dma_mask is set to 0xffffffffffffffff)
      our dma_mask will be u64 set to 0xffffffffffffffff even if we set it to
      DMA_BIT_MASK(32) previously. Meaning we do not reset the upper bits.
      By using the dma_alloc_coherent_mask function - it does the proper casting
      and we get 0xfffffffff.
      
      This caused not working sound on a system with 4 GB and a 64-bit
      compatible sound-card with sets the DMA-mask to 64bit.
      
      On bare-metal and the forward-ported xen-dom0 patches from OpenSuse a coherent
      DMA-memory is always allocated inside the 32-bit address-range by calling
      dma_alloc_coherent_mask.
      
      This patch adds the same functionality to xen swiotlb and is a rebase of the
      original patch from Ronny Hegewald which never got upstream b/c the
      underlaying reason was not understood until now.

      xen: fix logical error in tlb flushing · ce7184bd
      Alex Shi authored
      While TLB_FLUSH_ALL gets passed as 'end' argument to
      flush_tlb_others(), the Xen code was made to check its 'start'
      parameter. That may give a incorrect op.cmd to MMUEXT_INVLPG_MULTI
      instead of MMUEXT_TLB_FLUSH_MULTI. Then it causes some page can not
      be flushed from TLB.
      
      This patch fixed this issue.

      udf: Fix data corruption for files in ICB · 9c2fc0de
      Jan Kara authored
      When a file is stored in ICB (inode), we overwrite part of the file, and
      the page containing file's data is not in page cache, we end up corrupting
      file's data by overwriting them with zeros. The problem is we use
      simple_write_begin() which simply zeroes parts of the page which are not
      written to. The problem has been introduced by be021ee4 (udf: convert to
      new aops).
      
      Fix the problem by providing a ->write_begin function which makes the page
      properly uptodate.

      xen/p2m: Fix one-off error in checking the P2M tree directory. · 50e90041
      Konrad Rzeszutek Wilk authored
      We would traverse the full P2M top directory (from 0->MAX_DOMAIN_PAGES
      inclusive) when trying to figure out whether we can re-use some of the
      P2M middle leafs.
      
      Which meant that if the kernel was compiled with MAX_DOMAIN_PAGES=512
      we would try to use the 512th entry. Fortunately for us the p2m_top_index
      has a check for this:
      
       BUG_ON(pfn >= MAX_P2M_PFN);

      powerpc: Don't use __put_user() in patch_instruction · 636802ef
      Benjamin Herrenschmidt authored
      patch_instruction() can be called very early on ppc32, when the kernel
      isn't yet running at it's linked address. That can cause the !
      is_kernel_addr() test in __put_user() to trip and call might_sleep()
      which is very bad at that point during boot.
      
      Use a lower level function instead for now, at least until we get to
      rework ppc32 boot process to do the code patching later, like ppc64
      does.
