      [PATCH] IDE 17 (not just cleanup) · a925c40f
      Martin Dalecki authored
      This is actually an attempt to remove some stall code from
      this driver. However if some *real* users complain (Not just
      the usuall: "Hey - if someone!" but the "Hey I'm using this!")
      I'm all open to reenable it. Since I prepared this patch
      yerstoday it doesn't contain the ide_module.h fixup. This will
      follow later.
      
      - Don't use the convoluted byte type in ide-pci.c. Just use the proper
         u8instead.
      
      - Move ide_get_or_set_dma_base to the only place where it's used and
         reorganize the code there by killing the unnecessary
         CONFIG_BLK_DEV_IDEDMA_FORCED configuration option.
      
      - Remove unfunctional CONFIG_PKT_TASK_IOCTL code.
      
      - Kill unused ALTSTAT_SCREW_UP code.
      
      - Tons of dead code removed from ide-taskfile.c (#if 0 #endif and
         friends)
      
      - Remove unused IDE_DEBUG macro as well as lots of other name space
         pollution from ide.h.
      
      - Start using the ide_lock spin-lock for protecting access to data
         structures instead of the excessive interrupt disabling games.
      
      - Shorten the proc ouput of the piix initialization module.
      
      - Remove special /proc tape "name" output from ide-tape.c. This was
         redundant data which should only show up on syslog anyway.
      
      - Kill the REALLY_FAST_IO undef from the ide.h. This was a mistake
         present since far too many years in this driver. The proper way to
         deal with broken systems is to define REALLY_SLOW_IO in system
         dependent headers or particular driver files.  We can always
         reintroduce it easy if real users will complain, since OUT_BYTE() and
         similar can be used as hooks. But I don't expect anybody reporting
         about this. Even on the most broken IDE chip in the world (cmd640
         at VLB) undefining this *always* worked for me. Nearly all the code
         pieces in the ide driver code *reverted* it's effects explicitly
         anyway.
      
      - Remove the obsolete CONFIG_BLK_DEV_4DRIVES support. This was supposed
         to support 4 drivers attached at one channel on some older chipsets,
         in esp. Tekram 690CD, in the last century. They where all supposed to
         work at a register set starting at the base address 0x1f0.  Before
         complaining that this is removing functionality, please note that this
         must have been broken for already quite a long time, since the ide
         driver didn't contain the special device selection methods implicated
         by this any longer.  It didn't scan   this port too if PCI host chip
         support was enabled (as it is in all those distributions around
         there).  On the other hand this is the most prominent case of
         incoherent use of the mate member in the struct hwif_s. And please
         think about how big the probability is, that there are systems out
         there, where there are actually 4 drivers on such a channel?
      
      - Streamline module initialization code by removing one shoot functions.
      
      - Make the WAIT_READY value used in case of CONFIG_APM or
         CONFIG_APM_MODULE the default, since this is what really reflects the
         behavior of modern drives. It won't hurt any other case and finally
         removing it is reducing the necessary coverage for overall driver code
         testing/analysis.
      
      - Move the IDE_LARGE_SEEK macro to the only place where it's actually
         used. Replace the IDE_MIN() and IDE_MAX() drivers with the obvious.
         Remove unused SPLIT_WORD and MAKE WORD from the local header.
      
      - Remove CMD640_DUMP_REGS from global scope, since there is no
         development done on this any longer. Finally, the way the host chip
         initialization routines are called changed in the time between allows
         this to remain fully local to the host chip driver in question.
      
      - Some spell checking of comments in the code. (Yeep I have extended my
         Vim to do this the "Word" way with nice undercurl lines... mozilla
         remains to be fixed...)

      Alexander Viro authored
      I've found what's going on there.  Basically, we should not use
      __user_walk() with LOOKUP_PARENT - nd->last.name is set to the last
      component of the name and freeing that name before we are done is not a
      good idea.

      [PATCH] 2.4.18, 2.5.5: I/O APIC through-8259A mode IRQ 0 routing · 04a868aa
      Maciej W. Rozycki authored
       There is a problem with the through-8259A mode for IRQ 0 on I/O APIC
      systems.  Depending on correctness of an MP table, IRQ 0 routing is either
      not registered at all or registered at a wrong pin.  As a result the 8254
      timer IRQ only works by an accident (it's edge-triggered and never
      disabled/enabled so it happens to survive this incorrect configuration).
      A visible effect is you can't change the affinity for IRQ 0.
      
       Following is a patch that fixes both cases referred to above.  The code
      looks obvious but it was additionally run-time tested just in case.  The
      issue is serious -- please apply the patch ASAP.  As no changes were done
      to io_apic.c since the development fork, the patch applies cleanly both to
      2.4 and to 2.5.
      
       Credit goes to Joe for discovering the affinity problem and providing a
      fix proposal (incorporated in the final one).

      [PATCH] 2.5.6-pre2 IDE cleanup 16 · 24ae9cff
      Martin Dalecki authored
      There is no such a thing like a ide-clean-15. Never was.  But here comes
      what has been done in ide-clean-16:
      
      - Apply a patch for the initialization of the second PIIX channel.
         Found by Daniel Quinlan <quinlan@transmeta.com>
      
      - Apply a patch for the DMA initialization of the serverworks chip.
         Ken Brownfield <brownfld@irridia.com>
      
      - Make the ata_operations methods immune against device type drivers,
         which donot provide them by separating the access to them out. Audit
         them all.
      
      - Resynchronize with 2.5.6-pre1.
      
      - Remove unused IDE_DRIVE_CMD, IDE_DRIVE_TASK, IDE_DRIVE_TASK_MASK,
         IDE_DRIVE_TASKFILE macros.
      
      - Disable configuration of the task file stuff. It is going to go away
         and will be replaced by a truly abstract interface based on
         functionality and *not* direct mess-up of hardware.
      
      - Resync with 2.5.6-pre2.
      
      - Add HPT entries to the fall-back list, since otherwise the driver
         won'trecognize the drives. We will have to make this the default
         behavior for allnot recognized host chip types.
      
      - Fix compilation with no PCI host chip support enabled.
      
      - Apply the overflow fixes for HPT366 by Vojtech Pavlik.
      
      - Kill the one-shoot functions ide_wait_cmd_taks() ide_wait_cmd() by
         moving them to the places where they are actually used. Fix a
         potential buffer overflow on the way.
      
      - Fix usage of ide.c as module. Thanks to Adam J. Richter for figuring
         out what was wrong.
      
      - Various cleanups all along as well as removal of TONS of
         unfinished/dead code.
      
      I think it's sometimes better to remove stuff, which isn't there,
      instead of hoping for a "magical day" where it will be finished.

      that return value later.

      During 2.5.5-pre schedule_tail was optimized away under UP.  We need it

      	bd_claim(bdev, holder) fails is device is already claimed by
      	somebody else; bd_release(bdev) gives device up.
      
      *	get_sb_bdev() claims device for fs_type; it means that we don't need
      	to look through entire least of superblocks anymore - just through
      	the list of superblocks belonging to that type (i.e. the same thing
      	we do for non-block filesystems; that will allow to merge quite a
      	bit of code afterwards).
      
      *	sys_swapon claims device for itself;  free exclusion with mounting,
      	end of problems with bogus set_blocksize().
      
      *	is_mounted() and is_swap_partition() are gone - what we actually
      	wanted was "try to claim device for ourselves".  Which we can do
      	now - without races inherent to is_mounted()/is_swap_partition().
      
      *	RAID lock_rdev() claims device for itself.  I.e. we get rid of
      	is_mounted() in there (BTW, is_swap_partition() was missing) and
      	we get protection both ways - not only RAID won't take an already
      	mounted device, but mount won't stomp on a device claimed by RAID.
      
      There are other places that would benefit from the same (e.g. ext3 with
      external journal almost definitely wants to claim device for itself).
      
      Notice that it's a cooperative thing - neither open() nor raw device stuff
      claim the block device, so they don't care if device is mounted, etc.  So
      we don't break fsck and friends - exclusion is between those who know that
      they want that exclusion.
