This patch removes the archdata and driver_data members of struct vio_dev
and uses the platform_data and driver_data members of the embedded struct
device instead.  I also declared a couple of routines static.

This is part of a work in progress.

Fix a problem discovered by Jeff Mahoney <jeffm@suse.com>, based on an initial
patch from Chris Mason <mason@suse.com>.

journal_get_descriptor_buffer() is used to obtain a regular old buffer_head
against the blockdev mapping.  The caller will populate that bh by hand and
will then submit it for writing.

But there are problems:

a) The function sets bh->b_state nonatomically.  But this buffer is
   accessible to other CPUs via pagecache lookup.

b) The function sets the buffer dirty and then the caller populates it and
   then it is submitted for I/O.  Wrong order: there's a window in which the
   VM could write the buffer before it is fully populated.

c) The function fails to set the buffer uptodate after zeroing it.  And one
   caller forgot to mark it uptodate as well.  So if the VM happens to decide
   to write the containing page back __block_write_full_page() encounters a
   dirty, not uptodate buffer, which is an illegal state.  This was generating
   buffer_error() warnings before we removed buffer_error().

   Leaving the buffer not uptodate also means that a concurrent reader of
   /dev/hda1 could cause physical I/O against the buffer, scribbling on what
   we just put in it.

   So journal_get_descriptor_buffer() is changed to mark the buffer
   uptodate, under the buffer lock.

I considered changing journal_get_descriptor_buffer() to return a locked
buffer but there doesn't seem to be a need for this, and both callers end up
using ll_rw_block() anyway, which requires that the buffer be unlocked again.

Note that the journal_get_descriptor_buffer() callers dirty these buffers with
set_buffer_dirty().  That's a bit naughty, because it could create dirty
buffers against a clean page - an illegal state.  They really should use
mark_buffer_dirty() to dirty the page and inode as well.  But all callers will
immediately write and clean the buffer anyway, so we can safely leave this
optimising cheat in place.

The ioctl to ethtool change broke that little detail...


I made the changes, Jeff agreed in principle, Red Hat owns them and I know
no reason they can't be contributed under the GPL v2 or later.

Requires: ethtool change

Several ethernet drivers have been broken by the ethtool support because
the ioctl code used to power the interface up and down as needed. Rather
than add this to each driver call Jeff Garzik suggested we add hooks
for before/after ethtool processing.

This patch implements them which makes fixing the PM stuff easier,
as the epic100 patch to follow will show. It also cleans up the
via-velocity driver pm/ethtool logic a great deal. As per Jeff's
request the before handler is allowed to fail the operation.

Adrian Bunk noticed that the tda1004x DVB frontend driver was broken and
sent a small patch that at least made the driver work again.

There was a discussion afterwards about the kernel syscall interface,
but at the end, the tda1004x DVB frontend driver is still non-functional.

This re-applies the temporary band-aid.

The paca struct contains a pointer to the current task, which is used
for the `current' macro.  For some reason, this field is a u64, and
every time we use it we need a cast, because it is really a pointer.
This patch cleans things up a little by making it a pointer to struct
task_struct and removing the casts.  It also removes a now-incorrect
comment which said that r13 contains current (it now holds
&paca[smp_processor_id()]).

Occasionally the ppc64 kernel emulates a usermode instruction, for
example in the alignment exception handler.  Kumar Gala pointed out
(in the context of the ppc32 kernel) that if the instruction was being
single-stepped, and we end up emulating the instruction, we should
then send the process a SIGTRAP as if it had not been emulated and the
process had then taken a single-step exception.  This patch implements
this for ppc64.

Ok, here you are! :)
Attached is a patch for linux-2.6.7-rc2. (though the patch hasn't changed
since -rc1)

Again a short description:
(the patch removes most of the changes done in linux-2.6.2)
1. Removed the local buffer of cyberjack_write, because something goes wrong
upon a write-request bigger than the buffer. Without this, a write-request
stalls with error -3.
2. Removed some usb_clear_halt() lines. Without this, the device doesn't even
open and returns -7.

It works for my cyberjack pinpad USB card reader on
- nforce2 chipset
- VIA KM266 chipset
- AMD Irongate chipset
