From: Dave Jones <davej@suse.de>
  kernel builds and boots with patch (with CONFIG_BLK_DEV_INITRD disabled).

(Trivial because CONFIG_BLK_DEV_RAM is Y if CONFIG_BLK_DEV_INITRD is Y)

	New helper:
path_lookup(name, flags, nd)
{
	int err = 0;
	if (path_init(name, flags, nd))
		err = path_walk(name, nd);
	return err;
}

Places doing that by hand converted to calling it.

Actually, quite a few of them were doing equivalent of __user_walk()
(getname() and if it was successful - call path_lookup() and putname()).
Converted to calling __user_walk().

	LOOKUP_POSITIVE is not needed anymore.  All callers of path_walk()
treat -ENOENT and negative dentry the same way.  If you want a proof of
correctness - I'll send it, but it's a couple of pages of induction, basically
boiling down to "let's show that for any N we can replace the
               if (lookup_flags & (LOOKUP_POSITIVE|LOOKUP_DIRECTORY))
                       break;
in link_path_walk() with
               if ((lookup_flags & (LOOKUP_POSITIVE|LOOKUP_DIRECTORY)) ||
		   current->link_count <= N)
                       break;
without changing behaviour of the system".  Pretty straightforward for
N = 0, then we look for places that can lead to call link_path_walk()
with current->link_count equal to N and show that if result of the test
changes, behaviour of callers doesn't.  Since the depth of recursion is
limited, we had shown that test in question can be replaced with if (1).
And that's the only place in tree the ever checks for LOOKUP_POSITIVE.

	The real reason behind that is very simple - indeed, suppose
we get a negative dentry out of path_walk().  What the hell could we
do with it?  Its parent isn't locked, so both the name and parent can
change at any moment (could have changed already).  There used to be
places that tried to play "let's get a negative dentry, lock its parent
and start doing something".  All of them racy and all of them fixed
in 2.3.  Fixed by switching to LOOKUP_PARENT...

	More cleanups (getblk() use, etc.) in reiserfs (again, cleaning
up after merge).

into penguin.transmeta.com:/home/penguin/torvalds/repositories/kernel/linux

	* stat() variants on ppc64 converted to use of vfs_stat() and its ilk.
	* missing LFS checks added.

* minor cleanup in jffs (passing superblock instead of ->[si]_dev).

* in intermezzo a bunch of places where we are comparing ->s_dev
  are replaced with comparing pointers to superblocks.

* in reiserfs: a new caller of getblk() converted to sb_getblk() +
  a bunch of places converted to use of ->s_id.

* write_some_buffers(), write_unlocked_buffers(), wait_for_buffers(),
  wait_for_locked_buffers() and wait_for_some_buffers() converted
  from kdev_t to struct block_device *.

* sync_buffers() split in two functions (sync_buffers() and
  sync_all_buffers()).  Callers of sync_buffers(NODEV) are
  using the latter, those who actually pass a device - the former.
* sync_buffers() switched from kdev_t to struct block_device *.

* all remaining callers of sync_inodes() and sync_supers() pass
  NODEV as an argument, so we can make them void(void).  Dead
  code removed.

* new function - fsync_bdev() (analog of fsync_dev(), but takes
  struct block_device * instead of kdev_t.  Callers of fsync_dev()
  that have struct block_device in question are using fsync_bdev()
  now.
* old code for fsync_dev(NODEV) had been moved to sys_sync().
  Other callers of fsync_dev(NODEV) are calling sys_sync() now.
* fsync_dev() became a wrapper fro fsync_bdev().
* sync_dev() (not used anywhere in the tree) is gone.
* i2oblock.c had fsync_dev() called in ->release().  Removed.
* s390/block/xparm.c was doing fsync_dev() on its devices in
  cleanup_module().  Removed.

	Pettersson.
	* drivers/parport/ChangeLog: Updated.

Most importantly this patch is making ide.c use the
new automagic for module initialization lists and further
preparing the rest of the code in question here for proper
module separation. Despite this the CMOS probe has been removed
as well... *Iff*, which I don't expect, this breaks anything
it can be reintroduced easely. During this effort an actual bug
in the initialization of the main module has been uncovered as well.
a quite serious BUG has been tagged in ide-scsi.c as well, but
as far as now I just didn't get along to actually fixing it.
(The patch is big enough as it is).

Details follow:

- Kill *unused* ide_media_verbose() funciton.

- Remove the unnecessary media and supports_dma fields from
    ide_driver_t.

- Remove the global name field from ide_driver_t struct by pushing it
    down to the places where it's actually used.

- Remove the unused hwif_data field from ide_hwif_t.

- Push the supports_dsc_overlap condition up to the level where it
    belongs: disk type as well.

- Make the initialization of ide main ide.c work with the new module
    initialization auto-magic instead of calling it explicitly in
    ll_rw_block.c This prevents the ide_init() from being called twice. We
    have BTW. renamed it to ata_module_init(), since  ata is more adequate
    then ide and xxx_module_init corresponds better to the naming
    conventions used elsewhere throughout the kernel.

    This BUG was there before any ide-clean.  It was worked around by a
    magic variable preventing the second call to succeed.  We have removed
    this variable in one of the previous patches and thus uncovered it.

- Kill proc_ide_read_driver() and proc_ide_write_driver(). The drivers
    already report on syslog which drives they have taken care of.  (Or
    at least they should). In esp. the proc_ide_write_driver() was just
    too offending for me.  Beleve it or not the purpose of it was to
    *request a particular* driver for a device, by echoing some magic
    values to a magic file...
    More importantly this "back door" was getting in the way of a properly
    done modularization of the IDE stuff.

- Made some not externally used functions static or not EXPORT-ed.

- Provide the start of a proper modularization between the main module
    and drivers for particular device types. Changing the name-space
    polluting DRIVER() macro to ata_ops() showed how inconsistently the
    busy (read: module  busy!) field from ide_driver_t
    is currently used across the    different device type modules.
    This has to be fixed soon.

- Make the ide code use the similar device type ID numbers as the SCSI
    code :-).  This is just tedious, but it will help in a distant
    feature. It helps reading the code anyway.

- Mark repettitive code with /* ATA-PATTERN */ comments for later
    consolidation at places where we did came across it.

- Various comments and notes added where some explanations was missing.

This is finally moving the ide-pci.c file into a shape where
the host chip detection lists can finally be moved to where they
belong - into the particular chipset specific files.

This is accomplished, by a rather obivous removal of macro magic,
which was just making entries to the global device type
list nonfunctional, instead of making them conditional on the
corresponding CONFIG_BLHA options.

The second thing was to add a flag field to the device recognition
list, which made it possible to compress many of the
multi || chip id conditionals go away.

The only other file affected is ide.h - here is the change in the size
of the name field, which apparently slipped through ide-clean-12...

1. Add some notes to Documentation/driver-model.txt about how and
     and where to mount the driverfs.

2. Reorganize and prepare the PCI scanning code for proper device
dependant splitup. Basically tedious cleanup of macro games.

3. Use struct pci_dev name field as the name of PCI host dapaters
instead of invention ambigious IDE special names. This makes
the kernel bootup messages look a bit shifted, since those names are bit
longer, but makes up for consistance and should allow one later
to rearage things to fit into the generic PCI device initialization
mechanisms provided by the kernel.

4. Set 3. Allowed us to make the host chip specific
pci_init_xxx class functions have the proper signature of
module initializers. This will make it possible to make true
modules out of them later.

5. Make some functions in cmd64x.c static which where not used
elsewhere.

6. rename ide_special_settings to trust_pci_irq - this is reflecting
it's functionality better. And make it match the pci device vendor
as well as the device ID. It was a BUG to match only the device id!.

7. Make the chanell setup more tollerant for BIOS-es which don't
report IO and MEM bases properly. The code found previously there
tryed but was inconsistant.

8. Start to use proper terminology in ide-pci.c: host chip, channel,
drive instead of hwif, port, drive...

9. Enlarge the name field from ide_hwif_t to 64 bytes. It was only 6
previously and there where custom names there which where exceeding
this!!! But since we use the proper pci devce name there now instead,
we had to extend the size of this field anyway.

10. Add some explanatory comments and fix misguiding comments here and
there.

11. Kill the proc_ide_write_config and proc_ide_read_config brain
damage! Those where backdoors to the pci configuration registers on PCI
devices and IO registers on directly connected ISA ATA controllers.
They didn't discrement between them!

Access to both of them *simply* doesn't belong into an operating system,
which is supposed to abstract out the access to hardware! Did I mention
that access to both can be done from user land without an IDE special
interface! Any program which was using them (I hardly beleve there is
one) just deserves to loose. The programmer responsible for it
deserves to be fired immediately.

12. Move ide_map_xx and ide_unmap_xx tinny bio level wrappers away
from the "global" ide.h to where those are actually used and kill
trivial wrappers for otherwise generic bio_ routines. Just fighting
code obfuscation. The "rq->bio is used or is not there" brain
damage in ide-taskfile.c has to be fixed later. Possibly by killing
ide-taskfile.c alltogether, becouse this should be a driver for
users and not a driver for ATA disk disaster recovery companys...

13. Kill hwif->pci_devid and hwif->pci_venid. Just use the already
present hwif->pci_dev field instead.

14. Kill unused big switch ide_reinit_drive function. This silly
functon was switching upon every possible device driver cathegory
and calling the correspondng reinit function directly. This
idiocy was fortunately not used.

That's all... Most will be clear if one starts looking at the changes
in ide.h of course...

In contrast to the previous patches this one is actually fixing two
serious bugs.


The next direct step will be to kill the sigle place global PCI device
type recognition list from ide-pci.c by pushing the entries to where
they belong -> the host chips setup modules.

1. Start of driver tree usage upon suggestion from Pavel Machek.
     This still will needs a lot of further work in the future, but
     the current code doesn't hurt anything and allowa Pavel to work
     further from the base line. In esp. natively implemented
      suspend to file requires this - which I would love to see comming
     in,since I'm quite frequently using a notebook myself.

2. Kill the _IDE_C macro, which was playing games on entierly
     unnecessary declarations inside of header files in esp ide_modes.h

3. Replace the functionally totally equal system_bus_block() and
     ide_system_bus_speed() functions with one simple global
     variable: system_bus_speed. This saves quite a significatn amount of
     code. Unfortunately this is the part, which is makeing this
     patch to appear bigger then it really is...

4. Use ide_devalidate_drive() directly instead of idedisk_revalidate().

5. Kill conditional CONFIG_KMOD as well as some other minor tweaks.

Well this isn't that much in terms of functionality,  but it took me
quite q bit of time to catch up on the patch-2.5.5.gz ;-)

This is finishing the cleanup parts already started in ide-clean-9.

It kills the ide_register_module() and ide_unregister_module() as well
as associated idiosyncracies alltogether. It turns out
that this patch is actually fixing a bug which was present in the
driver before: the sub-module initialization functions where called
at least twice - which is an abundance.

Tough there is a bit of global namespace pollution caused by this
patch - but I'm aware of it and will fix it just a bit later.
(The terminology used inside the IDE code is anyway nothing common
else in the linux universum...)

The next targets will be:

1. Code obfuscation by "wrappers" around generic BIO level functions.

2. ide_hwgroup_t - which is only used to serialize multiple
discs on the same interrupt and similar. This is however a tough one.

3. There is a plenty of code waste in the chipset drivers, where there
is baroque informative code for the proc file system for static stuff,
which in fact belongs just to syslog(). In fact the default RedHat
distribution kernel is killing this gratitious abuse of the /proc
concept since a long long time...

I'm still awaiting the day of /proc/GPL, where GPL contains the
full text of it...

go ahead and free the inodes too, don't try to age them any
more (the aging has been done on a dentry level).
