      [PATCH] ext2_fill_super breakage · 7048ea4d
      Andrew Morton authored
      In 2.5.7 there is a thinko in the allocation and initialisation
      of the fs-private superblock for ext2.  It's passing the wrong type
      to the sizeof operator (which of course gives the wrong size)
      when allocating and clearing the memory.
      
      Lesson for the day: this is one of the reasons why this idiom:
      
      	some_type *p;
      
      	p = malloc(sizeof(*p));
      	...
      	memset(p, 0, sizeof(*p));
      
      is preferable to
      
      	some_type *p;
      
      	p = malloc(sizeof(some_type));
      	...
      	memset(p, 0, sizeof(some_type));
      
      I checked the other filesystems.  They're OK (but idiomatically
      impure).  I've added a couple of defensive memsets where
      they were missing.

      Martin Dalecki authored
      - Apply Pavel Macheks suspend resume double resume fix.
      
      - Finally remove the busy field for ata_operations and replace it with
         MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT.
      
      - Fix ali15xx chipset support by removing initialization differences,
         apparently caused by mislead interpretation of the specs or a mismatch
         between the specification and reality.
      
      - Guard calls to ide_set_handler with checks to see whatever the previously
         installed IRQ handler already served it's purpose.
      
      - Convert timeout checks on poll_timeout to the time_before() interface.
      
      - Consolidate the two different IRQ handlers for multi mode PIO writes into
         one. The problems remain the same but at least now we will only have to
         tangle one single problem.

      [PATCH] 2.5.7 IDE 27 · ff3c2cbb
      Martin Dalecki authored
      - Make for less terse error messages in ide-tape.c.
      
      - Replaced all timecomparisions done by hand with all the proper timer_after()
         commands.
      
      - Remove the drive niec1 mechanisms alltogether. There are several reasons for
         this:
      
         1. The code implementing it is nonintelliglible and therefore propably
         broken.
      
         2. If we have to invent somethig about sceduling drive IO, it should be done
         on the BIO level.
      
         3. We may in fact interleave with the IO sceduling on the upper layers and
         the results of two overlapping signal filters overlapped with each other can
         be disasterous to the overall throughput. (In fact they *are* most of the
         time.)
      
         4. It was not working if you had intermixed modes on different drives
         DMA versus PIO.
      
         5. Our goal is to have a driver which is able to share the badwidth
         properly and shouldn't needing this kind of "tuning".
      
      - Remove unused nice2 from disk struct.
      
      - Rename channel member of ata_channel to unit and device to dev to
         just prevent wrong interpretations. This prevents constructs like
         channel->channel...

      Martin Dalecki authored
      - Mark all members of structures, which get jiffies assigned or involved in
         ugly timeout calculations with the prefix PADAM_  for easy spotting. This is
         Polish for "I'm falling down" or "This brings me to the knees" or slag
         comment for "What a sh..". Please be assured that it doesn't sound vulgar.
      
         Please grep for it to see immediately why this nomenclature is justified.
      
      - Rename hwifs_s to ata_channel and eliminate ide_hwifs_t as well as the HWIF
         macro. OK this step makes this patch rather big.

      [PATCH] 2.5.7 IDE 25 · e07a6a66
      Martin Dalecki authored
      - Replace the task_io_reg_t with the simple u8. There is no need to obfuscate
         the code more then necessary.
      
      - kill some unnecessary type definitions out from hdreg.h.
      
      - Add proper attributes to register files in hdreg.h.
      
      - Don't use raw arrays for tfRegister and hobRegister in ide_task_s.  Use out
         nice global structures describing the fields in them.  This allows to kill
         the following defines:
      
           IDE_DATA_OFFSET
           IDE_FEATURE_OFFSET
           IDE_NSECTOR_OFFSET
           IDE_SECTOR_OFFSET
           IDE_LCYL_OFFSET
           IDE_HCYL_OFFSET
           IDE_SELECT_OFFSET
           IDE_COMMAND_OFFSET
      
         and many many others.
      
      - Please have a look at the following in pdc4030.c. It couldn't have worked!
         This has been fixed in one go with the above change:
      
         memcpy(args.hobRegister, NULL, sizeof(struct hd_drive_hob_hdr));
      
      - Kill the redundant *_REG_HOB definitions. They don't help readability in any
         way.

      Martin Dalecki authored
      - Push BAD_DMA_DRIVE and GOOD_DMA_DRIVE to the ide-pmac.c file, since this is
         the only place where those get used.
      
      - Kill unused fields from the ide_task_s structure. In esp. we pass a task
         attached to a request and not the other way around!
      
      - Rename hwif field to channel in struct ide_drive_s.
      
      - Move the request queue to the level where proper serialization has to happen
         anyway - the channel structure.

      Martin Dalecki authored
      - Support for additional Promise controller id's (PDC20276).
      
      - Remove code duplication between do_rw_taskfile and do_taskfile.
         This will evolve into a more reasonable ata_command() function
         finally. The ata_taskfile function has far too many arguments, but
         I favour this over having two different code paths for getting
         actual data to the drive.

      [PATCH] 2.5.7-pre2 IDE 22a · 198231a8
      Martin Dalecki authored
      - Apply more patches from Vojtech Pavlik for the handling of host chip setup.
         Hopefully they are settled now.
      
      - Kill unused CONFIG_BLK_DEV_MODES
      
      - Push register addressing down in to task_vlb_sync.
      
      - Make the taskfile parsing stuff actually readable. This is compressing the
         code by an incredible amount. We use just one function doing the whole
         scanning right now. This should make sure that the IRQ handler used by a
         particular command is always right.  I didn't introduce typos hopefully
         here.
      
      - Don't call ide_handler_parser as argument for do_taskfile() any longer. We
         have killed this function by coalescing it's functionality with
         ide_cmd_type_parser() anyway.
      
      - Kill unused SLC90E66 code, which Vojtech apparently missed in his patch.
      
      - sync up with 2.5.7-pre2
      
      Once again the actual patch is rather big mostly due to the removal of
      some default configuration variables which are not used anylonger. So time for
      the next patch stage.

      [PATCH] PATCH -- pci_pool and CONFIG_DEBUG_SLAB · b286bd16
      David Brownell authored
      I got burnt one too many time by mismatches between
      the pci_pool and "real" slabs... something changed in
      mm/slab.c and broke a driver, so I'm going for the real
      fix this time.  Having poisoning that _works_ is a huge
      help in the innards of the USB host controller drivers.
      
      This patch gets rid of some #ifdefs and makes the pci_pool
      code poison memory if CONFIG_DEBUG_SLAB is set.
      The functionality has always been there, but this makes
      it simpler to get at.

      USB serial drivers · c3cdeb68
      Ganesh Varadarajan authored
      Several functions in the serial drivers can be called from bottom
      half or interrupt context. They must use the GFP_ATOMIC flag for
      calls to kmalloc() and usb_submit_urb().
        
      Functions which must use GFP_ATOMIC:
      1. All *_callback() functions.
      2. Any code which is inside a spinlock.
      3. write(), throttle(), unthrottle(), which may be called by
         the line discipline in bottom half context.
        
      Functions which can use GFP_KERNEL:
      1. open(), close(), startup(), shutdown(), set_termios().

      USB Urefs for hid-core/hiddev · 36a9bab9
      Paul Stewart authored
        I've written a patch Vojtech and I discussed for enhancing the
      hiddev code to optionally provide more detailed output on read().
      The old functionality is still supported by default, and in
      situations where HID usage codes are unique across reports, the
      old method is still preferable due to its terseness.
          
        The new method provides the ability to determine exactly which
      value has changed, in cases where the HID usage codes are not  
      unique.  It also provides a means to optionally receive notification
      when input reports are received from the device, whether or not
      any of the values in the report have changed.
      
        The details of the changes are as follows:
        
        - All current code behaves identically
      
        - A new ioctl pair HIDIOCGFLAG/HIDIOCSFLAG gets and clears
          flags on the hiddev device.                             
      
        - If you set the flag HIDDEV_FLAG_UREF, the read() call switches
          from reading hiddev_event structures to hiddev_usage_ref
          structures.  The change takes effect immediately, even to
          already queued events that haven't been read() yet.  Here's
          an example of enabling FLAG_UREF:                          
      
          {
              int flag = HIDDEV_FLAG_UREF;
              if (ioctl(fd, HIDIOCSFLAG, &flag) != 0) {
                      perror("ioctl");
                      exit(1);
              }
          }
        
        - With the HIDDEV_FLAG_REPORT set (which is only allowed if
          HIDDEV_FLAG_UREF is also set), there is a special uref that
          will be read() in addition to the ones corresponding to
          changes in the device state: when uref.field_index is set to
          HID_FIELD_INDEX_NONE, this uref is a notification that the
          report referred to by report_type and report_id has been
          received from the device.  This can be useful in situations
          when the notification of the arrival of a report is useful
          even if there is no change in state.
