      [PATCH] SMP signal latency fix · 0db87bc9
      Ingo Molnar authored
      The code that sends a signal needs to "kick" the target process if it
      runs on another CPU and wasn't woken up by the signal to let it know
      that it has a new event.
      
      Otherwise it might take a long time until the target actually notices
      and acts on the signal.

      [PATCH] Fix oops in x86-64 strace path · ae40e4b5
      Andi Kleen authored
      Fix a nasty typo found by Albert Cahalan.
      
      This lead to an oops when a invalid syscall was called under strace in 2.6.

      [PATCH] Fix TSS limit on x86-64 · 954caecd
      Andi Kleen authored
      The limit of the TSS segment was incorrectly set to a too big value
      on x86-64. This lead to the CPU reading random memory behind the main
      TSS when iopl was >0, but there was no ioperm bitmap set. This caused
      random failures in port accesses in this state.
      
      Set the correct limit.

      Don't fold nanosleep() into clock_nanosleep(). · 35d64a33
      Linus Torvalds authored
      The latter has buggy restart functionality and is a lot
      more complicated anyway.

      [PATCH] fix reference count bug with class devices · 59ccfc46
      Greg Kroah-Hartman authored
      When a kobject is associated with a kset, the kset MUST be set before
      the kobject is initialized (by either a call to kobject_register() or
      kobject_init()).  This patch fixes the class code which improperly set
      the kset after the kobject was initialized, which would cause improper
      reference counts on the kset.
      
      Thanks to Mike Anderson for locating the source of this bug.

      [PATCH] Fix IP checksum for SuSE 9.0 compiler · 6077b1d3
      Andi Kleen authored
      The hammer branch based gcc 3.3 in SuSE 9.0 has a more aggressive
      optimizer. ip_send_check has this code:
      
      	iph->check = 0;
      	iph->check = ip_fast_csum((unsigned char *)iph, iph->ihl);
      
      The new gcc optimizes the first store away because it doesn't know
      that ip_fast_csum reads its input memory. This leads to occassionally
      packets with wrong IP header checksum getting sent; this happens especially
      with NFS. Fixing it in the constraints would have been ugly and probably
      not future proof, so this patch just adds a memory clobber to ip_fast_csum.
      
      For some reason the issue only hits in 2.6, we haven't seen it in 2.4.
      Problem occurs on both i386 and x86-64.
      
      Credit goes to Olaf Kirch for tracking this down.

      [PATCH] USB: usb ignores 64bit dma · 4f428f01
      David Brownell authored
      The dma hooks whereby EHCI can pass 64bit DMA support
      up the driver stack (to avoid buffer copies) turn out
      to broken on most architectures(*).  This patch just
      disables them all, since it looks like those mechanisms
      won't get fixed before 2.6.0-final.  For now it'd only
      matter on a few big Intel boxes anyway.
      
      Please merge.
      
      - Dave
      
      (*) On x86, mips, and arm dma_supported() doesn't
           even compare with the device's mask.  On several
           other architectures (reported on ppc, alpha,
           and sparc64), asking that question for non-PCI
           devices will just BUG() -- even though all info
           needed to answer the question is right at hand.

      [PATCH] Fix cramfs metadata races · 0aef2868
      Alexander Viro authored
      There's a few places that use incorrect exclusion for the cramfs raw
      data access buffers.  The proper lock is "read_mutex" (and BKL does
      nothing).
      
       - fix mount-time read and block number initialization without the mutex
         held. 
       - cramfs_readdir() needs to copy the name and inode information into a
         separate buffer since it can't hold the semaphore over the
         (potentially blocking) user mode access
       - cramfs_lookup() needs to hold the access lock over the whole
         function, not just the read itself
       - use generic_file_llseek on directories to get i_sem exclusion on
         readdir/lseek
