On SMP systems, preempt_count is erroneously set to 1 for idle task's on
all CPU besides CPU0.  This patch sets preempt_count properly.

	Robert Love

I see that this is fixed now in 2.2 and 2.4, but 2.5 still has broken
BSD partition handling.  Here a fix.

Andries

 - Fix bug in tw_aen_complete() where aen's could be lost.
   Fix tw_aen_drain_queue() to display useful info at init.
   Set tw_host->max_id for 12 port cards.
   Add ioctl support for raw command packet post from userspace
   with sglist fragments (parameter and io).
 - Fix read capacity to under report by 1 sector to fix get
   last sector ioctl.
 - Fix bug where more AEN codes weren't coming out during
   driver initialization.
   Improved handling of PCI aborts.
 - Fix bug in tw_findcards() where AEN code could be lost.
   Increase timeout in tw_aen_drain_queue() to 30 seconds.
 - Re-write raw command post with data ioctl method.
   Remove raid5 bounce buffers for raid5 for 6XXX for kernel 2.5
   Add tw_map/unmap_scsi_sg/single_data() for kernel 2.5
   Replace io_request_lock with host_lock for kernel 2.5
   Set max_cmd_len to 16 for 3dm for kernel 2.5
 - Set host->max_sectors back up to 256.
 - Modified pci parity error handling/clearing from config space
   during initialization.
 - Better handling of request sense opcode and sense information
   for failed commands.  Add tw_decode_sense().
   Replace all mdelay()'s with scsi_sleep().
 - Revert mdelay's and scsi_sleep's, this caused problems on
   some SMP systems.
 - Add pci_set_dma_mask(), rewrite kmalloc()/virt_to_bus() to
   pci_alloc/free_consistent().

 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).

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

Added files:

it's too big for kmalloc.

    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.

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 *)
