      [ARM] 3443/1: [S3C2410] Improve IRQ entry code · 26f91fd5
      Ben Dooks authored
      Patch from Ben Dooks
      
      Remove the old debug from the IRQ entry code,
      update the comments on the handling of the
      IRQ registers.
      
      The message "bad interrupt offset" is removed
      as it is only helpful for debugging, and can
      cause printk() flooding when under load.
      
      Make the code to deal with GPIO interrupts
      faster, and use the same path to deal with
      unexplained results from the IRQ registers.

      [ARM] 3439/2: xsc3: add I/O coherency support · 23759dc6
      Lennert Buytenhek authored
      Patch from Lennert Buytenhek
      
      This patch adds support for the I/O coherent cache available on the
      xsc3.  The approach is to provide a simple API to determine whether the
      chipset supports coherency by calling arch_is_coherent() and then
      setting the appropriate system memory PTE and PMD bits.  In addition,
      we call this API on dma_alloc_coherent() and dma_map_single() calls.
      A generic version exists that will compile out all the coherency-related
      code that is not needed on the majority of ARM systems.
      
      Note that we do not check for coherency in the dma_alloc_writecombine()
      function as that still requires a special PTE setting.  We also don't
      touch dma_mmap_coherent() as that is a special ARM-only API that is by
      definition only used on non-coherent system.

      [ARM] 3438/1: ixp23xx: add pci slave support · 532bda5d
      Lennert Buytenhek authored
      Patch from Lennert Buytenhek
      
      On the Double Espresso board, the IXP2350s are PCI slave devices and
      we skip calling pci_common_init() as that enumerates the bus.  But even
      though we are a PCI slave device, there is still some PCI-related setup
      that has to be done.
      
      Create ixp23xx_pci_common_init(), move the common initialisation bits
      there, and have this function called from both the PCI master and the
      PCI slave init path.

      [CIFS] Incorrect signature sent on SMB Read · e9917a00
      Steve French authored
      Fixes Samba bug 3621 and kernel.org bug 6147
      
      For servers which require SMB/CIFS packet signing, we were sending the
      wrong signature (all zeros) on SMB Read request.  The new cifs routine
      to do signatures across an iovec was not complete - and SMB Read, unlike
      the new SMBWrite2, did not fall back to the older routine (ie use
      SendReceive vs. the more efficient SendReceive2 ie used the older
      cifs_sign_smb vs. the disabled  cifs_sign_smb2) for calculating signatures.
      
      This finishes up cifs_sign_smb2/cifs_calc_signature2 so that the callers
      of SendReceive2 can get SMB/CIFS packet signatures.
      
      Now that cifs_sign_smb2 is supported, we could start using it in
      the write path but this smaller fix does not include the change
      to use SMBWrite2 when signatures are required (which when enabled
      will make more Writes more efficient and alloc less memory).
      Currently Write2 is only used when signatures are not
      required at the moment but after more testing we will enable
      that as well).
      
      Thanks to James Slepicka and Sam Flory for initial investigation.

      [PATCH] avoid unaligned access when accessing poll stack · 30c14e40
      Jes Sorensen authored
      Commit 70674f95:
      
        [PATCH] Optimize select/poll by putting small data sets on the stack
      
      resulted in the poll stack being 4-byte aligned on 64-bit architectures,
      causing misaligned accesses to elements in the array.
      
      This patch fixes it by declaring the stack in terms of 'long' instead
      of 'char'.
      
      Force alignment of poll and select stacks to long to avoid unaligned
      access on 64 bit architectures.

      [PATCH] Document Linux's memory barriers [try #7] · 108b42b4
      David Howells authored
      The attached patch documents the Linux kernel's memory barriers.
      
      I've updated it from the comments I've been given.
      
      The per-arch notes sections are gone because it's clear that there are so many
      exceptions, that it's not worth having them.
      
      I've added a list of references to other documents.
      
      I've tried to get rid of the concept of memory accesses appearing on the bus;
      what matters is apparent behaviour with respect to other observers in the
      system.
      
      Interrupts barrier effects are now considered to be non-existent. They may be
      there, but you may not rely on them.
      
      I've added a couple of definition sections at the top of the document: one to
      specify the minimum execution model that may be assumed, the other to specify
      what this document refers to by the term "memory".
      
      I've made greater mention of the use of mmiowb().
      
      I've adjusted the way in which caches are described, and described the fun
      that can be had with cache coherence maintenance being unordered and data
      dependency not being necessarily implicit.
      
      I've described (smp_)read_barrier_depends().
      
      I've rearranged the order of the sections, so that memory barriers are
      discussed in abstract first, and then described the memory barrier facilities
      available on Linux, before going on to more real-world discussions and examples.
      
      I've added information about the lack of memory barriering effects with atomic
      ops and bitops.
      
      I've added information about control dependencies.
      
      I've added more diagrams to illustrate caching interactions between CPUs.
