      [PATCH] More wh patches · a0992864
      Stuart MacDonald authored
      Inlined are a few more patches to 2.5.43 that fix problems that
      were discovered during QA.
      
      1-firm4.07 :: I've moved to the bottom since it's huge
      
      Updates the firmware to 4.07. Fixes a bug introduced in 4.05 where
      RTS is high after boot. Also fixes a bug where the whiteheat would
      allow data reception after boot when no ports were open.
      
      2-fix-dtr-rts
      
      I didn't know this, but the firmware open command also handles
      raising the signals for me. This code is superflous.
      
      3-fix-read-urb
      
      Read polling was started right away in whiteheat_open(). Coupled
      with the firmware bug fixed above where data could be received
      by a port that wasn't open, this caused the whiteheat_read_callback
      to fire before open() was finished, and in some cases this caused
      harm to the tty layer. I didn't track down the exact mechanism
      because either moving the read polling to the last operation of open()
      or using the fixed firmware caused the crash to stop happening. I
      have stack traces if you'd like to have a look; it looks like something
      scribbles on the stack, but I couldn't figure out what eactly, as the
      scribbled data didn't match anything in the whiteheat driver or the
      test applications.
      
      4-fix-ixoff
      
      RELEVANT_IFLAG masks off the software flow control bits, so that
      a change that is restricted to the soft flow bits will be ignored. This
      is the email I sent earlier; I've decided to just not use the macro for
      now, but I'd still like to know if the macro should be fixed,.

      [PATCH] usb: problem clearing halts · 236d8160
      David Brownell authored
      This is a slightly cleaned up version of that earlier patch:
      
      - Makes both copies of the clear_halt() logic know that
         usb_pipein() returns boolean (zero/not) not integer (0/1).
         This resolves a problem folk have had with usb-storage.
         (I looked at kernel uses of usb_pipein and it really was
         only the clear_halt logic that cares.)
      
      - Removes some code from the "standard" version; no point
         in Linux expecting devices to do something neither Microsoft
         nor Apple will test for.

      [PATCH] usbnet, preliminary zaurus support · 2c6bb9c0
      David Brownell authored
      This is Pavel's patch, with some cleanups and re-sorting of
      the various SA-1100 cases.  According to Pavel this works
      as well as his earlier version ... which is to say, maybe
      not yet, he saw a uhci "very bad" error (on 2.5.43).
      
      I'm sending it along since it's clearly the right way to
      support the Zaurus, and it can't be that far off given the
      code I've seen.

      [PATCH] ohci-hcd, longer bios handshake timeout · d8bf5435
      David Brownell authored
      This should resolve the problems Nicolas Mailhot reported,
      where an old BIOS seemed reluctant to release the controller
      and the dbg() message delayed things enough to work.  At
      worst, it'll eliminate dbg() messages as a factor.

      [PATCH] device removal · a49c4f6a
      Patrick Mochel authored
      The problem was that when the refcount hit 0, it was unconditionally
      assuming that it had been added, which is wrong.  The patch below
      corrects that, and fixes the Oops when loading the floppy driver.

      [PATCH] add linux/ioctl32.h header for 2.5.43 · 1a19232d
      Andi Kleen authored
      Several ports (x86-64,ppc64,sparc64) which do 32bit ioctl emulation
      have functions for drivers to let them define their own translation
      handlers. So far it was a bit complicated to use because there
      was no standard include file that declares the prototypes for this
      stuff. Then drivers and other subsystems can start to declare their own
      ioctl translation handlers.
      
      This patch add include/linux/ioctl32.h to fix this.
      
      The actual implementation is in arch specific code. It has been coordinated
      with DaveM and Anton.
      
      This patch is needed for the x86-64 merge I sent in separate mail.
      
      There is currently no preprocessor symbol that the drivers can test
      to see if they should use this. So far they have to check arch symbols.
      This will be fixed later when all 64bit ports that need it add the dynamic
      ioctl registration API too (that's ia64,s390x,mips64)

      Andi Kleen authored
      This fixes a few files that got lost with the last merge and merges
      with 2.5.43/i386.  Only changes architecture specific files.
      
      It depends on one other patch (for linux/ioctl32.h) which I'm sending
      separately.
      
      Changes:
      - Include missing files (pageattr.c) and Makefile changes
      - Update IA32 subsystem. Various small fixes and a big merge
        with sparc64.
      - Change HZ to 1000
      - Merge some of the 2.5.43/i386 profiling changes. No full oprofile yet.
      - Fix many warnings
      - Update defconfig
      - Various other smaller cleanups and bugfixes.

      [PATCH] RCU helper patchset 2/2 · a0b6c9c1
      Dipankar Sarma authored
      This adds a set of list macros that make handling of list protected
      by RCU simpler. The interfaces added are -
      
      list_add_rcu
      list_add_tail_rcu
      	- Adds an element by taking care of memory barrier (wmb()).
      
      list_del_rcu
      	- Deletes an element but doesn't re-initialize the pointers in
      	  the element for supporting RCU based traversal.
      
      list_for_each_rcu
      __list_for_each_rcu
      	- Traversal of RCU protected list - takes care of memory barriers
      	  transparently.

      [PATCH] RCU helper patchset 1/2 · 0ec69870
      Dipankar Sarma authored
      This first RCU helper patch adds a read_barrier_depends() primitive
      to all archs which is NOP for archs that doesn't require an rmb()
      for data dependent reads when writes are ordered using a wmb().
      In reality, only alpha requires an rmb(), the rest are NOPs.
      It is likely to be necessary in most situations that would use RCU.
      Please apply.
      
       Description :
      
      Sometime ago, during a discussion on lock-free lookups, it was
      agreed that an additional memory barrier interface,
      read_barrier_depends() that is lighter than an rmb(),
      is necessary to make sure that data-dependent reads are not
      re-ordered over this barrier. For many processors, data-dependency
      enforces order, so this interface is a NOP, but for those that don't
      (like alpha), it can be a rmb().
      
      For example, the following code would force ordering (the initial
      value of "a" is zero, "b" is one, and "p" is "&a"):
      
          CPU 0                           CPU 1
      
          b = 2;
          memory_barrier();
          p = &b;                         q = p;
                                          read_barrier_depends();
                                          d = *q;
      
      because the read of "*q" depends on the read of "p" and these
      two reads should be separated by a read_barrier_depends().  However,
      the following code, with the same initial values for "a" and "b":
      
          CPU 0                           CPU 1
      
          a = 2;
          memory_barrier();
          b = 3;                          y = b;
                                          read_barrier_depends();
                                          x = a;
      
      does not enforce ordering, since there is no data dependency between
      the read of "a" and the read of "b".  Therefore, on some CPUs, such
      as Alpha, "y" could be set to 3 and "x" to 0.  rmb()
      needs to be used here, not read_barrier_depends().

      [PATCH] PnP Rewrite V0.9 - 2.5.43 · f72e5c5c
      Adam Belay authored
      The included patch is essentially a Linux Plug and Play Support rewrite.  It
      contains many significant improvements, including the following:
      
      
      1.)  A Global Plug and Play Layer
          - Now drivers do not have to worry about which plug and play
            protocol they are using.  Calls are made directly to the Linux
            Plug and Play Layer and then forwarded to the appropriate
            protocol.
          - This will make it very easy to integrate ACPI PnP support when
            it's ready
      
      
      2.)  A complete Plug and Play BIOS driver
          - The Plug and Play BIOS now supports reading and writing of
            resource configurations.
          - It is now possible to enable disabled PNPBIOS devices.  Therefore
            the user can safely enable PnP OS support in their BIOS.
      
      
      3.)  Driver Model Integration
          - The entire plug and play layer is integrated into the driver model
          - The user interface is housed here
          - PnP protocols are listed under the bus "pnp"
      
      
      4.)  A powerful global resource configuration interface
          - The user can use this to activate PnP devices for legacy and
            user-level drivers
          - See the documentation for how to configure devices.
      
      5.)  Automatic resource allocation for needed devices
      
      
      6.)  A PnP device name database
      
      And many more improvements.
      
      This patch also adds me to the maintainers list, considering the current
      PnP maintainer has been inactive for over 2 years now.
