      [PATCH] fix scsi oops on failed sg table allocation · 7dbe32be
      Jens Axboe authored
      This patch fixes the deliberate BUG_ON() on failed sgtable allocations.
      I left that in because I was too lazy to fix it at the time...
      
      Basically make scsi_init_io() return 0 on failure (like before) but this
      time allow us to recover. scsi_init_io() will end_request on a fatal
      condition. So now just mark the device/host as starved if needed, and
      leave the request at the front of the queue for next service.

      [PATCH] Micro Memory battery backed RAM card driver · 76e7b902
      Neil Brown authored
      New driver for Micro Memory NVRAM module
      
      This driver handles up to 16 PCI based NVRAM cards
      from MicroMemory.
      Each card appears like a block device, and can be partitioned
      using any standard partitioning tool.  Upto 15 partitions are
      supported.
      
      This driver needs its own major device number and so allocates
      one using register_blkdev.

         between PCI and non PCI host code.
      
      - pdc202xxx updates from Thierry Vignaud.

      Martin Dalecki authored
      - Propagate the queue handling changes to pmac as well.
      
      - Move set_transfer to ide-taskfile.c this is the only place where it's used
         and it can be made static there. Same applies to ide_ata66_check().
      
      - Move ide_auto_reduce_xfer to ide.c.
      
      - Make ide_cmd() local to the only place where it's used. Rename it to
         drive_cmd(). Don't pass drive_cmd_intr() as parameter.
      
      - Remove ide_next command completion type. Nobody is using it.
      
      - Move ide_do_drive_cmd to ide-taskfile. It's used there and in sub-drivers.
         Not in ide.c. The usage inside the device type drivers is entirely bogus
         inconsistent and so on...
      
      - Kill bogus IRQ masking code. The kernel is supposed to handle this properly.
         We should not try to work against possible bugs in the overall irq handling
         code. Wow this is increasing the systems overall responsibility by a
         significant margin.
      
      - Remove disfunctional pdcadma code. It is only misleading to the user.

      [PATCH] 2.5.15 IDE 62a · 5ff49f70
      Martin Dalecki authored
      - Streamline device detection reporting to always use ->slot_name.
      
      - Apply 64 bit sector size fixes to the overall code.
      
      - Push ->handler down to the struct ata_channel.
      
      - Introduce channel group based locking instead of a single global lock for all
         operations. There are still some places where we have preserved the ide_lock.
         We can't lock for queues during device probe and we protect global data
         structures during device registration and unregistration in ide.c with it.
      
      - Start replacement of serialized access to the registers of
         channels which share them with proper host chip driver specific locking.
         This affects the following host chip drivers:
      
         cmd640.c, rz1000, ... ?
      
         Seems some are setting the serialize flag just in case. So better let's do it
         gradually over time.
      
         Well, I still have to think whatever we really need to put channels sharing
         an IRQ line in the same locking group.
      
         From now on the sick concept of a hw group is gone now. We have full blown
         per channel request queues! Hopefully I will be able soon to get my hands on
         a dual Athlon machine to check how this all behaves on a multi SMP machine.
      
      - Move the whole SUPPORT_VLB_SYNC stuff to the only place where it is used: the
         pdc4030 host chip driver.  Eliminate it from the global driver part.
      
      - Eliminate pseudo portability macros from pdc4030. This is a host chip firmly
         based on VLB.

      - Don't disable interrupts during ide_wait_stat(). I see no reason too.

      This patch further cleans up and separates the code in an effort to
      allow setting (a) a larger maximum real-time priority than default and
      (b) a maximum kernel RT priority that is separate than the maximum
      priority exported to user-space.

      [PATCH] USB-UHCI-HCD · a96a4b53
      Georg Acher authored
      After maturing for more than a month, I decided that it's enough...
      So here's the patch for the HCD-version of usb-uhci, I called it
      usb-uhci-hcd. For me, the usual devices work (TM).
      
      Since the internals haven't changed much, I don't expect much difference to
      usb-uhci in functionality and performance.
      
      There is one major improvement: I've added a (preliminary) watchdog, that
      regularly checks whether UHCI interrupts are coming through. If they are
      "missing", ie. the HC halted without saying so, the HC is "re-animated" by a
      real and clean restart, which is (internally) equivalent to a module-reload.
      This is especially for VIA-chips which get comatose quite easily by babble
      or other incorrect transfers.
      
      The side effect is, of course, disconnects for all connected devices, but
      they re-appear after a few seconds and were dead before anyway. So keyboard
      and mouse work again, which is IMO a _very_ useful thing :-)
      
      Another point: The watchdog (currently with moderate 8 interrupts/s) detects
      IRQ-problems, so the misleading "device doesn't accept new device"-message
      is replaced by an immediate error.
      
      More comments and the separation into multiple files (I've taken ohci-hcd as
      an example) should make the code more concise...
      
      A few things are still on the todo-list and will come later:
      - A few watchdog modifications (fewer interrupts, better diagnostics)
      - Support for module "tune"-parameters for breadth/depth search, debug etc.
      - interval support for ISO
      - More SMP-tests
      - maybe changes for reference counting when it is clear what survives :-)

      [PATCH] 2.4.19-pre8 uhci.c incorrect bit operations · 448c86dd
      Johannes Erdfelt authored
      This fixes up a couple of problems I came across while working on
      uhci-hcd. There are a couple of places where shifts are used where they
      shouldn't be and others where should be.
      
      This cleans up a couple of cases and tidys it up.
      
      The patch is relative to 2.4.19-pre8 and my other patches, but it's
      alright to wait for 2.4.20. It should also be applied to 2.5.

      [PATCH] uhci-hcd for 2.5.15 · 7ed10dbc
      Johannes Erdfelt authored
      So I finally hunkered down and got uhci-hcd working. I was surprised how
      easy it was to make the modifications for hcd.c.
      
      This patch has received a moderate amount of testing so far. I've played
      with various devices and haven't had any problems. I won't claim it's
      bug free yet and I'll continue doing more testing.
      
      The patch includes a small change to hcd.c to not call free_config if
      the HCD doesn't implement it.
      
      There are some other messages that get printed such as:
      
      hcd.c: usb_hcd_pci_remove 00:10.0, count != 1
      
      but it appears from the code that this is just a soft warning that all
      of the references to the bus aren't freed yet. This isn't a bug.
      
      Differences from usb-uhci/usb-uhci-hcd:
      - Cleaner code. uhci-hcd is based off of uhci, so it maintains the same
        look and feel as well as readability.
      - Faster. The tests I've run so far show that uhci-hcd is faster in
        every case than usb-uhci-hcd
      - It does not have the watchdog type feature for VIA chipsets. It's
        something that is definately possible to implement, but I'd like to
        find out what Windows does first.
      
      Differences from uhci:
      - Modified to use the hcd.c framework. This removed a significant amount
        of code and nesessitated lots of little changes.
      - Big endian support. I haven't been able to test it on a big endian
        machine yet, but atleast 90+% of the work should be done. Once I get
        my PowerPC working again, I'll test this and submit any appropriate
        patches. This was the biggest functional change between uhci.c.
      - No more urb->next processing. Completely ripped out.
      - urb->interval support for Isochronous pipes.
      - A couple of bug fixes for some problems I noticed while working on the
        code. These will be submitted for uhci.c in a seperate email.

      [PATCH] USB device reference counting api cleanup changes · 04adba5a
      Greg Kroah-Hartman authored
      This patch replaces the awkwardly named usb_inc_dev_use() and
      usb_dec_dev_use() with usb_get_dev() and usb_put_dev() to match the
      naming convention of the rest of the kernel's reference counted
      structures.  It also does away with the special case of usb_free_dev(),
      and has usb_put_dev() be the same thing (through a #define, just like
      usb_free_urb() works.)
      
      Now when the last person calls usb_put_dev() or usb_free_dev() the
      structure is cleaned up.  This allows the different host controller
      drivers to implement their logic differently if they want to (as they
      do), and everyone can be happy and stop arguing about the "proper" way
      to write their host controller drivers :)

      [PATCH] USB device reference counting fix for uhci.c and usb core · 25f04c13
      Johannes Erdfelt authored
      Earlier in the 2.5 development cycle a patch was applied that changed
      the reference counting behaviour for USB devices.
      
      There are a couple of problems with the change:
      - It made the USB code more complicated as a whole with the introduction
        of an additional cleanup path for devices. Using the traditional method
        of reference counting, cleanup is handled implictly
      - It reduces functionality by requiring a callback for all references to
        the device, but doesn't provide a method of providing callbacks for
        references. It relies on the hardcoded device driver ->disconnect and
        HCD ->deallocate method for callbacks
      
      The traditional method of using reference counting supports as many
      reference users as needed, without complicating it with mandatory
      callbacks to cleanup references.
      
      The change in 2.5 also only helps catch one subset of programming
      problem in device drivers, the case where it decrements too many times.
      That is of dubious debugging value.
      
      So, this patch reverts the change and makes the reference counting
      behave like it does in the rest of the kernel as well as how the USB
      code does in 2.4.
      
      This patch doesn't remove all of the superfluous code. Some drivers,
      like usb-ohci, ohci-hcd and ehci-hcd have some code that is no longer
      needed. I wanted to spend some more time with those drivers since the
      changes weren't as trivial as uhci.c and usb-uhci.c.
      
      I've tested with uhci and usb-ohci with no adverse effects.
