      [PATCH] Misc. fixes for ALPS TDLB7 DVB frontend driver · e1bd9bfd
      Michael Hunold authored
       - applied latest changes by Juergen Peitz (great work!)
        o as a workaround for the lockup problem the data valid signal is
          checked after every channel switch.  If it is not set FEC parameters
          are set again.
        o disabled autoprobing if FEC settings are known (from sp887x). 
        o added support for FE_READ_UNCORRECTED_BLOCKS (from sp887x).
        o added support for FE_SLEEP (from sp887x).
        o bit error rate is now not only read from register 0xC07 but also
          from 0xC08 (from sp887x). 
        o I2C feedthrough to the tuner is now only enabled when needed (from
          sp887x).
        o Added FE_CAN_QAM_AUTO and FE_CAN_HIERARCHY_AUTO to
          dvb_frontend_info.
        o Removed obsolete setting of default frontend parameters in
          sp8870_init.
        o Removed obsolete module parameter 'loadcode' because changes in the
          saa7146 driver made firmware loading very fast.

      [PATCH] More barriers in module code. · fe3f6208
      Rusty Russell authored
      Paul McKenney convinced me that there's no *guarantee* that all archs
      will refuse the speculate the atomic ops above the state test, eg:
      
      CPU0 (stopref_set_state)		CPU1 (stopref)
      
       atomic_set(&ack, 0);			if (state == XXX)
       wmb();						atomic_inc(&ack);
       state = XXX;
      
      Certainly Alpha needs a rmb() inside stopref to guarantee it sees
      the same ordering.

      [PATCH] ipt_limit fix for HZ=1000 · b6e31b8e
      Rusty Russell authored
      The range that the iptables limit extension can specify depends on HZ.
      This means that rules which worked i386 2.4 (100 HZ) won't work on
      2.6.
      
      The solution is to adjust the precision based on the HZ value (keeping
      the range of possible values the same).  For extra geek cred, this is
      done by calculating a power-of-two constant below the maximum
      multiplication factor, which gcc then turns into a simple shift.

      [PATCH] Fix compile on PPC · 19d4808f
      Paul Mackerras authored
      At the moment the aty128fb and matroxfb frame buffer drivers don't
      compile on PPC.  In both cases the error is pretty trivial.  This
      patch is the minimum change to fix the problems.
      
      The _IOR() type problem fix in aty128fb.c depends on the fact that the
      size of a pointer is the same as "size_t", so we don't have to use
      _IOR_BAD() to keep the ioctl number the same.

      [PATCH] futex bug fixes · 8462805c
      Jamie Lokier authored
      This fixes two serious bugs in the futex code.
      
      One is a race condition which results in list corruption when
      FUTEX_REQUEUE is used.  It is due to the split locks change introduced
      in 2.6.0-test6, and oopses when triggered.
      
      The other is a security hole.  A program can use FUTEX_FD to create
      futexes on mms or inodes which don't reference them, and when those
      structures are reused by a different mm or inode, the addresses match.
      The effect is that a malicious or flawed program can steal wakeups from
      completely unrelated tasks, causing them to block (or worse if they are
      counting on the token passing property).
      
      These are the specific changes:
      
          1. Each futex_q retains a reference to its key mm or inode.
      
          2. The condition for a futex_q to indicate that it's woken can usually
             be interrogated lock-free.
      
          3. futex_wait calls the hash function once instead of three times,
             and usually takes the per-bucket lock once too.
      
          4. When a futex is woken, the per-bucket lock is not usually taken,
             so that's one less cache line transfer during heavy SMP futex use.
      
          5. The wait condition and barriers in futex_wait are simpler.
      
          5. FUTEX_REQUEUE is fixed.  The per-bucket lock juggling is done
             in such a way that there are no race conditions against the tests
             for whether a futex is woken.
      
      
      This patch is an combination of patches previously sent to the list.  An
      equivalent patch has been in Andrew Morton's tree for a while, with no
      failure reports.  Also I have been running it on my own SMP box for a
      while.  Conversely, we have received an oops report for the 2.6.0-test6
      code, so the fix is needed.

      [PATCH] set sigio target to current->pid and only if not already set · c69f2894
      Jamie Lokier authored
      1. send_sigio() sends to a specific thread, _not_ a process.
         (It can also send to a process group, but that's not relevant here).
         This is useful, and should stay as it is.
      
         Therefore it makes _no sense_ to call f_setown() with current->tgid.
         Presently the kernel is inconsistent about it, with some places using
         current->pid and some others using current->tgid.
      
         This patch changes f_setown() calls to use current->pid.
      
      2. In some places, f_setown() is called not at the user's direct request,
         but as a side effect of another function.  Specifically: dnotify and
         file leases.
      
         It is good to allow a program the flexibility to specify a different
         pid than the default, using F_SETOWN.  Presently they can do this after
         the dnotify or lease call, but there is a small time window when it
         will be temporarily set to current->tgid (which as pointed out above,
         is not always right).
      
         The window is avoidable if the program can use F_SETOWN prior to the
         dnotify or lease call.  This is exactly what the "force" argument to
         f_setown() is for, and this patch changes it to zero in those callers.
      
         This change is not likely to affect any existing programs.

        - Support synchronous directio only. Defer asynchronous directio until

        - Ensure we revalidate stale attribute info.

      [PATCH] APIC fixes for x86-64 · 21add34f
      Andi Kleen authored
      Various APIC/ACPI fixes for x86-64. This brings us closer to working
      out of the box on the now popular VIA and NVidia Nforce3 based Athlon64
      and Opteron boards. To be really good we would need more ACPI changes
      (still waiting for that to be all merged through the usual channels).
      
      With this we mostly work with acpi=off at least.
      
      Also it syncs us up with bugfixes done in 2.4.
      
       - Disable IO-APIC by default on non SMP VIA/NVidia boards.  This is a
         bit of a hack, but needed to work around ACPI bugs.  Can be
         overwriten with "apic". 
       - Add acpi=ht, meaning run ACPI boot setup, but do not enable the
         interpreter.  Same as i386.
       - Stop MADT parsing early when local APIC or IO-APIC are disabled
       - Add more option parsing early enough to actually change the boot
         process
       - Update documentation for command line options
