      [PATCH] Fix broken domain debugging (aka "isolcpus option broken") · bea1dc68
      Nick Piggin authored
      Fix an oops in sched_domain_debug when using the isolcpus= option.
      
      Also move a debug check for validating groups into the "for-each-group"
      loop, where it should be.

      The problem is in tcf_action_copy_stats, it assumes a->priv has
      the same layout as struct tcf_act_hdr, which is not true for
      struct tcf_police. This patch rearranges struct tcf_police to
      match tcf_act_hdr.

      [PATCH] off-by-1 libata-scsi INQUIRY VPD pages 0x80 and 0x83 · 21d3de02
      Douglas Gilbert authored
      I have some code (in sginfo) that requests the first 4 bytes
      of SCSI INQUIRY VPD pages to get their length then asks for
      that exact length in a follow up request to fetch the payload.
      Just like I saw with 36 byte standard INQUIRYs (no fixed)
      I get a buffer  full or zeroes.
      
      BTW SCSI standards dictate that in situations where the allocation
      length (in the cdb) is less than what is needed that what can be
      sent shall be sent (i.e. truncated and without any error indication
      or modification to the part of the response returned).
      In other words it is up the the application client to take remedial
      action.
      
      Changelog:

      [libata] only DMA map data for DMA commands (fix >=4GB bug) · 046de9be
      Jeff Garzik authored
      libata made the assumption that (for PIO commands in this case)
      it could modify DMA memory at the kernel-virtual address, after
      mapping this.  This is incorrect, and fails on e.g. platforms that
      copy DMA memory back and forth (swiotlb on Intel EM64T and IA64).
      
      Remove this assumption by ensuring that we only call the DMA mapping
      routines if we really are going to use DMA for data xfer.
      
      Also:  remove a bogus WARN_ON() in ata_sg_init_one() which caused
      bug reports (but no problems).

      [PATCH] dvb: documentation update · 1a6b6b96
      Michael Hunold authored
      Start of a big DVB update.
      
      
      The reasons for revamping the DVB frontend architecture:
      
      Just as analog TV cards, DVB cards need some sort of tuner to tune to the
      desired frequency of the digital transponder.  Tuning alone doesn't give you a
      digital DVB datastream, however, you need a demodulator as well.  The
      combination of tuner and demodulator is called frontend in the DVB world.
      Tuner and demodulator are both accessed via the serial i2c bus on all DVB
      cards out there.  So, technically a frontend consists of two i2c helper
      chipsets.
      
      In former times when there was only a handful of different DVB cards, the
      frontend was encapsulated in one tin box.  Some people had the idea that there
      should be one "frontend driver" instead of dedicated tuner and demodulator
      drivers.  A bad idea.
      
      As time went on, different manufacturers used the same tuner and demodulator
      combination, but used a different wiring for the tuner or did other technical
      changes.  The only possibility to support different cards with one combined
      frontend driver was to add hardware dependent tuner code inside the generic
      i2c frontend drivers.  Yuck.
      
      So there was a need for communication between the i2c frontend driver and the
      hardware depenedent driver, for example to exchange initialization code for
      the tuner.  Unfortunately, the i2c infrastructure is one way, from the i2c
      client to the i2c adapter using a non-typesafe ioctl() like interface, which
      is ugly by itself.  Greg K-H and others refused the idea to add an iotctl()
      like interface from the i2c adapter to the i2c client and instead proposed to
      use a typesafe interface instead.  We all agreed with that.
      
      The existing i2c infrastructure heavily depends on the probing facility, ie.
      clients probe for their existence on i2c busses.  This is dumb for most i2c
      busses out there that sit on dedicated hardware.  A DVB card is uniquely
      identified with pci or usb subvendor and subsystem ids, so on that particular
      bus we exactly *know* which kinds of i2c helper chipsets sit on there.
      
      Up to now this wasn't a problem, because we could fix all conflicts manually
      until half a year ago.  By that date, we found two different DVB designs which
      used different demodulators that unfortunately use the same i2c address and
      which cannot be distinguished by hardware tricks (ie.  different number of
      registers, some fixed hw dependent register,...)
      
      Getting a usable DVB card depended on the load order of the modules, because
      the i2c core probed the demodulator drivers one after another and the first
      one won the race.  Compiling all drivers statically into the kernel resulted
      in non-working cards.
      
      Our solution is as follows: we agreed to keep the basic underlying kernel i2c
      infrastructure, but we decided not to register our bussed and chipsets to the
      kernel i2c "probing" infrastructure.  Instead, we killed the tuner parts of
      the frontend drivers and put them into the dedicated hardware drivers (this is
      were they technically belong, they are highly hardware dependent) and we
      changed the frontend drivers to pure demodulator drivers (which are hardware
      independend).  There is now a type-safe functional dependency between the
      drivers and the demodulator drivers, the drivers explicitely ask the
      demodulator drivers to attach to their i2c bus.  The only negative aspect of
      that approach is that for some hardware there are now more dependencies to
      demodulator drivers than needed, ie.  a small amount of memory is wasted.

      [PATCH] restore BLKRRPART semantics · 6695ad97
      Andries E. Brouwer authored
      In 2.6.8 the code for the BLKRRPART ioctl was changed
      to return EIO when no partitions were found, such as
      on an empty disk. This breaks some partitioning programs
      and is also confusing: "Input/Output error" while in fact
      nothing was wrong with this brand new all blank disk.
      
      This restores old behaviour.

      [PATCH] PPC64 Close firmware stdin · c22df075
      Paul Mackerras authored
      We recently found a problem that was causing memory corruption during
      boot on IBM POWER5 machines.  The problem was that the if you have a
      USB keyboard and it is set to the input device for the firmware, it
      will still be active when the kernel is started.  That means that the
      OHCI controller has pointers to various memory areas that it polls for
      transfers to do.  When we start using that same memory in the kernel,
      bad things can happen.  (This isn't a problem on powermacs because the
      Apple OF implements a "quiesce" call which turns off all the devices
      it is using.)
      
      This patch fixes the problem by calling the Open Firmware "close"
      method for the input device.  Stephen Rothwell and I have verified
      that doing this fixes the problem on the POWER5 machine where we
      observed it.  I verified that this patch doesn't cause any problems on
      powermacs.
      
      I think this patch should go into 2.6.10 since it fixes a nasty memory
      corruption bug that can cause rather subtle and hard-to-diagnose
      problems during boot.  (The symptom on the POWER5 machine with the
      particular kernel that we were using was that reading /proc/net/tcp
      would oops, due to one of the pointers in tcp_ehash being corrupted.)
