In order to support some new taskfile protocols, particularly ATAPI,
the setup-and-start-DMA hook needs to be split into its component
pieces, 'setup' and 'start'.

For PCI IDE-style controllers, most of the code is moved into the
'setup' portion, with the 'start' portion only flipping a single
bit in hardware.

* bug fix: make sure 'nsect' member of struct ata_queued_cmd is
initialized each time a cmd is re-used.  Only affects PIO data xfers,
which nobody uses.
* slightly change the way a device's flags are printed out.  currently
the only flag is 'lba48', but soon 'wcache' will appear also.
* add WB-cache-related constants and macros to linux/ata.h

This fixes a corruption problem with overlapping copyarea()'s
in the radeon driver.

At the moment, on PPC64, the instruction we use for wmb() doesn't
order cacheable stores vs. non-cacheable stores.  (It does order
cacheable vs. cacheable and non-cacheable vs. non-cacheable.)  This
causes problems in the sort of driver code that writes stuff into
memory, does a wmb(), then a writel to the device to start a DMA
operation to read the stuff it has just written to memory.

This patch solves the problem by adding a sync instruction before the
store in the write* and out* macros.  The sync is a full barrier that
orders all loads and stores, cacheable or not.  The patch also moves
the eieio instruction that we had after the store to before the load
in the read* and in* macros.  With the sync before the store, we don't
need an eieio as well in a sequence of stores, but we still need an
eieio between a store and a load.

I think it is better to do this than to turn wmb() into a full memory
barrier (a sync instruction) because the full barrier is slow and
isn't needed with the sync in the write*/out* macros.  This way,
write*/out* are fully ordered with respect to preceding loads and
stores, which is what driver writers expect, and we avoid penalizing
users of wmb() who are only doing cacheable stores.

	ntfs_fill_super() and ntfs_read_inode_mount() cleaned up.  Removed
the kludges around the first iget() on NTFS.  Instead of playing with
(re)setting ->s_op we have the MFT_FILE inode set up by explicit new_inode()/
set ->i_ino/insert_inode_hash()/call ntfs_read_inode_mount() directly.
That kills the need of second super_operations and it allows to return
error from ntfs_read_inode_mount() without resorting to ugly "poisoning"
tricks.

Ok, well there aren't too many folks using an QLA2100 in a fabric
topology, if there were, they wouldn't have gotten very far in the
driver load sequence.  I've been able to scrape-up a QLA2100, 1Gig
switch, and an JBOD.  Upon loading the 8.00.00b12k driver, the
firmware successfully logs into the switch, the driver receives a
LOOP_UP event, but, the kernel panics due to NULL pointer dereference
while trying to perform an RFT_ID  -- the attached patch against
current scsi-misc-2.6 fixes that problem.

The patch to close all the open/close/hotplug races in sr left the
module refcounting broken so that the ULD housing the CD device now
can't be removed until the device itself is removed.

This patch (structurally identical to the one for sd.c to perform the
same function) fixes the module refcounting.

This fixes a situation where the handler can exit too early.

Set up SMT for the domain scheduler on x86-64.  This way the scheduling
works better on HyperThreading aware systems; in particular it will use
both physical CPUs before sharing two virtual CPUs on the same package. 
This improves performance considerably in some cases.

From: Rusty Russell <rusty@rustcorp.com.au>

PowerPC64 ABI has ".funcname" (the actual function) and "funcname" (the
function descriptor) and we strip off the dots in "dedotify" called from
module_frob_arch_sections().  We need to also de-dotify the corresponding
names in the __version section.

Actually has nothing to do with __down, it's just that we only print the
first symbol whose version is missing.

From: Paul Mackerras <paulus@samba.org>

It turns out that we are not handling the TABDLY bits of the termios
c_oflag field correctly on PPC, PPC64 and Alpha.  These three architectures
have a value for XTABS that is different from the TAB3 value.  POSIX
specifies that setting the TABDLY field to TAB3 should result in tabs being
expanded to spaces.  In n_tty.c:opost() we check for O_TABDLY(tty) ==
XTABS, which is fine on most architectures because they have XTABS == TAB3.

I think the right thing to do is just to change the definition of XTABS to
be the same as TAB3 on these architectures.  The patch below does this for
PPC and PPC64 (and I suggest the Alpha maintainer should do the same).  At
the moment, applications using either the XTABS or TAB3 values won't get
the expected behaviour.  With this patch, apps that use TAB3 will get the
expected behaviour.  Apps that use XTABS will need to be recompiled (but
note that the POSIX-specified name to use is TAB3 not XTABS).

    I would just like to say that I have no difficulties with intermezzo
    being rm -rf'd.  There are probably only a handful of users.  

    In the past 4 years nobody has supported InterMezzo sufficiently for
    it to become successful.  I have been fortunate to get really good support
    for the Lustre project.  So I have focussed on that.  Lustre 1.X has
    become really solid.

    The disconnected operation, caching and mirroring functionality of
    InterMezzo will become available in Lustre as a new feature in version 2. 

     So I see no point in keeping InterMezzo if it is a nuisance.
