Logics around "if not ready, schedule the same step again" taken
out of ps_tq_intr() and into the steps that need it.

Removed junk (see the analysis in the previous patch), removed
ps_set_intr() arguments.

Preparation to crapectomy - expanded include of pseudo.h, split
the part of pd_do_request() into pd_do_request1(), leaving in pd_do_request()
only the check that FSM is not running and call of pd_do_request1().
Added locking analysis - it's in drivers/block/paride/Transition-notes
and it will be used on the next step.  Even though the subsequent steps are
small, they rely on properties of the damn thing and proof of these properties
is hairy.  Amazing perversions people manage to produce when writing a trivial
FSM - the code is very convoluted for no good reason...

* new helper: pi_schedule_claimed() - pi_do_claimed() sans the call
  of continuation if we don't have to wait; returns 1 if we don't
  have to wait and 0 otherwise.

	daisy.c used to access the topology list with no locking whatsoever.
Protected by spinlock, fixed numerous bugs in handling of the single-linked
list (I'm not kidding - just take a look at the old parport_daisy_fini()
and weep; it is supposed to go through a simple list and remove all entries
that satisfy a condition).

	bw-qcam.c turned into proper parport driver.  Instead of (racy)
scanning the list of ports we use ->attach() and ->detach().

	parport_gsc.c turned into proper parisc driver; instead of scanning
the list of ports upon rmmod in search of ones that had been created by us,
we do cleanup where it belongs - in parisc driver ->remove().

	A bunch of parport_enumerate() users was duplicating parport_find_...()
without proper locking.  Replaced with use of appropriate helpers, races closed.

	We use a new mutex to protect all additions/removals of drivers and
ports.  That cures a lot of insanity:
	* driver removals can't hit us in the middle of attach_driver_chain().
Old code simply dies on that.
	* port removals can't hit us in the middle of driver registration.
Again, old code dies on that.
	* driver ->detach() is allowed to block now.
	* we are guaranteed that by the time when parport_unregister_driver()
returns, all ->detach() calls are finished.  Old code did _not_ guarantee
that (read: was inherently racy since rmmod of driver could race with port
removal and get driver->detach(port) called after the module was gone).
	* we are guaranteed that driver->attach(port) won't be called
more than once.  With the old code that was a matter of luck.
	* removed piles and piles of braindead code.

	Current tree has all allocated ports on portlist.  However,
most of the portlist users assume that we only have announced ports
there and break badly if they happen to see the list after port driver
has created a port (parport_register_port()) but before it finishes
the setup (and calls parport_announce_port()).
	The only place that wants to see all allocated port is
parport_register_port() itself and only to pick the first unused
port number.
	We add a new list (all_ports) and put ports there when allocated;
that list is kept ordered by port->number.  Ports are placed on portlist
only by parport_announce_port().
	Gobs of shite in parport_register_port() removed, pile of races
closed...

	Add PCI device support - there are atmel_pci.ko and atmel_cs.ko

Hi Jes.  I really do have a Rev. 5 card, and it works much better treated
as a Tigon I than as a Tigon II.

I send these a while ago but didn't get a reply.
Can you apply these patches for the hamradio drivers?

details:

+ scc.c usage of rtnl lock and register_netdev.
+ scc.c properly initialize timers.
+ remove cli() call in 6pack.c
+ fix init of reused devices and remove cli()
+ scc.c statistics

Hi !

I didn't include that with the bitkeeper based PowerMac updates so Jeff
can assume his role as maintainer/filter of network driver updates :)

Here's my latest update to this pmac-only driver, please apply if you
are ok with it. The driver now uses the macio infrastructure for
detection & power management notifications, getting into sysfs at
the same time.

Ben.

Now that Al Viro fixed cramfs, it works beautifully as an initrd

I've been chasing a weird SELinux bug which shows up mostly when doing
installs of a dev-* rpm (ie. creating and overwriting lots of block
device inodes), but which I've also seen when doing mkinitrd.

It turned out not to be an SELinux problem at all, but a core VFS
S_ISBLK bug.  It seems that SELinux simply widens the race window.

The code at fault is fs/fs-writeback.c:__mark_inode_dirty():

		/*
		 * Only add valid (hashed) inodes to the superblock's
		 * dirty list.  Add blockdev inodes as well.
		 */
		if (!S_ISBLK(inode->i_mode)) {
			if (hlist_unhashed(&inode->i_hash))
				goto out;
			if (inode->i_state & (I_FREEING|I_CLEAR))
				goto out;
		}

The "I_FREEING|I_CLEAR" condition was added after the ISBLK/unhashed
tests were already in the source, but I can't see any reason why we'd
want the I_FREEING test not to apply to block devices.  And indeed, this
results in all sorts of inode list corruptions.  Simply moving the
I_FREEING|I_CLEAR test out of the protection of the S_ISBLK() condition
fixes things entirely.

The existing 2.6 kernel will reliably fail on me in about 2 seconds once
"rpm -Uvh --force dev*.rpm" starts its actual installation of the new
inodes.  With the patch below I can't reproduce it at all.

The #include is the part of this patch that matters, so the #ifdef below
works.

The rest of the patch removes gratuitous duplication due to some strange
aversion to concision in the presence of #ifdef, the kind that is all too
common, utterly pointless, and error prone.
