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.

This is the Richard Henderson-approved, cleaner, brighter per-cpu patch.

Ok, I found it.  The problem was in the decompression code.

In inflate.c, in the routine zlib_inflate(), it reuses the passed-in "f"
parameter as a return value, but the PPP packet compression stuff needs
that return value later.

This patch adds two intermediate general cache sizes, 96 and 192 bytes.
On my system this saves about 34k.

size-256              63    180    256    5   12    1
size-192              95    120    192    5    6    1
size-128             213    240    128    8    8    1
size-96             1080   1120     96   28   28    1

During 2.5.5-pre schedule_tail was optimized away under UP.  We need it
for preempt-kernel, too, since it decrements the preempt_count to 0
coming off do_fork.

Without this patch, CONFIG_PREEMPT + !CONFIG_SMP does not gain one very
much.

	Below is a followup to bd_claim patch - it is the last one
from the current series.  Removes SWP_BLOCKDEV flag - it isn't needed
anymore.

*	new functions - bd_claim(bdev, holder) and bd_release(bdev).
	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.

	1.	moves a bunch of generic ioctls from sr_dev_ioctl() to
		cdrom_ioctl().
	2.	switches blk_ioctl() to struct block_device *
	3.	ditto for blkpg_ioctl()

	Missing export for dparent_lock.

This patch adds PCMCIA/CF support for the
PT Digital Board (CONFIG_SA1100_PT_SYSTEM3).

2nd try .... :)

Changed files:
linux/drivers/pcmcia/Makefile
linux/drivers/pcmcia/sa1100.h
linux/drivers/pcmcia/sa1100_generic.c
Added files:
linux/drivers/pcmcia/sa1100_system3.c

    Use vmalloc for ppp_deflate workspace. It's 400KiB, and kmalloc strangely
    doesn't seem to work very well for that :)
    
    Use schedule_task to do a delayed cleanup, because the z_comp_free routine
    is called with spinlocks held, hence we can't just call vfree().
    
    Fix double MOD_DEC_USE_COUNT when allocation fails, for both compression
    and decompression workspaces.
    
    Change licence text to one that insmod likes.

	- bug fix for lockup on SMP machines

This patch allow for no MSDOS partition manager for the ARM. There are many arm

2.5.x IRQ changes for PT Digital Board.
Also some code cleanups.

This is a minimal "get it working again" patch; there are plans a
foot to re-jig the page table code to work better with Ingo Molnar's
changes.  These same plans also allow the ARM page tabkes to fit
into Rik van Riel's rmap significantly better.

(We're currently abusing the struct page * returned from pte_alloc_one,
treating it as if it were the same as a pte_t *)

Major SA1100 generic DMA cleanup.
Fix suspend/resume bugs.
Provide and use new SA1111 generic driver for SA1111-based devices.

Thought I should add myself for the
"ehci-hcd" and "usbnet" drivers.

This is against 2.5.5 ...

Here is a batch of accumulated bugfixes and cleanups for the Coda kernel
module. Patch is against 2.5.6-pre2, I could also send these as separate
patches.

bugfix: Fix coda_dentry_revalidate bug

    Due to a bad test, coda_dentry_revalidate was forcing revalidation
    of cacheable inodes, and allowed caching of non-cacheable inodes.

bugfix: Corrected i_mtime/i_ctime setting

    i_mtime and i_ctime were not always updated when writing to a file,
    or when modifying inode attributes.

cleanup/optimization: Avoid getattr upcalls

    We can use coda_iget directly instead of coda_cnode_make when an
    upcall returns attributes and avoid the getattr upcall altogether.

cleanup: Removed debugging messages

    CDEBUG macros haven't been useful ever since the initial development
    when they were introduced. They are too verbose for debugging
    purposes. Removing these saves about a third of the compiled size of
    the module.

    Removed print_entry variable that was used by ENTRY/EXIT macros
    which are already gone.

cleanup/optimization: Readdir simplification

    Relying on the fact that the pagecache is already buffering far more
    efficiently, simplified coda_readdir implementation. We can now fill
    the complete userbuffer instead of returning after reading only 2KB.

    Passing dir entry types that are present in the venus_dirent
    structure to the user as well.

cleanup: Removed redundant permissions statistics counters.

    The permission check count is about identical to the 'permission'
    field in the VFS stats, and the permission hit counter can trivially
    be derived from upcall_stats.access - vfs_stats.permission. Removed
    these redundant counters.

cleanup: Removed useless test for c_flags in coda_revalidate_inode.

    We already know c_flags is set due to earlier tests.

as intended.

This implements ptes-in-highmem for PPC, removes the quicklist
and zero-page stuff.  PTEs in highmem on SMP turned out to need
some significant changes to avoid deadlocks on the hash_table_lock
(now renamed to mmu_hash_lock).  The PMDs now contain the physical
address of the PTE page rather than the virtual address.
Anything that takes the mmu_hash_lock now operates with the DMMU
off to avoid MMU hash-table misses.
