We shouldn't ever get into ->handler() if drive is busy so
just call ->error() unconditionally if status check fails.

Setup handler and output first data block directly from ->prehandler()
instead of calling ->handler().  The only change in functionality is that
we no longer check DRIVE_READY status bits (there is no need to do it).

 - in task_out_intr() fix off-by-1 bug and (stat & DRQ_STAT) check,
   previously "if" was always true for rq->current_nr_sectors == 1
 - fail request if DRQ_STAT is not set and rq->current_nr_sectors != 0
   (instead of setting handler and waiting for the next IRQ) or if DRQ_STAT
   is set but !rq->current_nr_sectors (in task_mulout_intr() this was OK)
 - in task_mulout_intr() check also DRIVE_READY and WRERR_STAT status bits

The hardware vendor, in their infinite wisdom, make the combined
mode configuration register different between ICH5 and ICH6.

Take this into account.

Obvious bug.  Fixes highmem oops.

Bugzilla #2905

During receive processing, the tg3 card updates rx_producer (the
hardware position in the receive ring) and the opaque cookie. Due to PCI
rules the stores happen in order. However the cpu may reorder the reads.

In these sort of cases there is usually a data dependency between
reading the index and looking up the data (since we use the index to
load the data). I think all cpus except alpha guarantee the reads
happen in order in this case.

However in this particular case we load hw_idx, compare it to sw_idx and
then use sw_idx to locate the opaque cookie. There is no data dependency
in this case. We need a read memory barrier between the read of
rx_producer and the opaque cookie to enforce ordering.

Thanks to Olof Johansson, Michael Chan and Broadcom for their assistance
in finding this bug.

airo creates /proc/driver/aironet/<device name> on device activation.
However, the device can be renamed - then on teardown it tries to remove
the wrong directory.  The removal of /proc/driver/aironet then runs afoul
of the BUG_ON() in remove_proc_entry.

This fixes it by keeping a copy of the name of the directory it created.

(It doesn't actually solve the problem of the stats directory still being
/proc/driver/aironet/eth0 when you rename the device to, say, 'joe'.  But
that patch would be a little less trivial.)

* The OID type for BSSID was incorrectly set to type SSID.
  It should be type RAW. This lead to interesting reporting
  by "iwpriv ethX g_bssid".
  (Which caused garbage output and possibly an out of bound)

* Be ultra-cautious in reporting SSID by changing the "%s"
  to "%.*s" and passing the length. (Prompted by the false
  type above, whereby length = 0 and a %s on a garbage field)

It's tulip driver, and tulip driver performs better than dmfe

Here it is.  The patch fixes all compile errors and warnings in
pci-skeleton.c.  The "debug" parameter lacks corresponding variable,
so I removed it to avoid a warning on module load.  Obsolete
pci_power_on() and pci_power_off() have been replaced with the new
code using pci_set_power_state(), pci_save_state() and
pci_restore_state().  The driver has been tested by compiling it as
module and as part of the kernel.

Using "-W" found a few places that should probably use signed
variables since they can contain (and check for) negative error
values.

While reading code, I found this buglet.  If the TIOCGWINSZ fails,
mconf.c assumes 24/80 as screen size, without honoring the LINES and
COLUMNS environment variables.  This is the shorter and IMHO more
correct version.

mcdx has different IRQ numbers for all drives; irq handler needs a
pointer to structure describing the drive in question.  However, instead
of passing such pointer at request_irq() time and having it passed to
mcdx_intr() for free, mcdx.c sticks the pointer in question into an
array indexed by IRQ number and has mcdx_intr() go look it up there. 

Cleaned up, array killed.

	Trivial annotations + typo fix in _snd_ioctl32_hwdep_dsp_image()
(we want to copy 32bit structure from userland, convert it to native one
and do normal ioctl on it; see the first changed line below for what's
really happening...)

	Missing '=' in C99 initializer

	Usual "inline used before definition" fixes in nsp32.c and sg.c

	Almost all are trivial, aacraid/linit.c annotations had caught a bug -
copy_from_user() where copy_in_user() should've been.

	Extraction of int from pointer is slightly broken in several places.

	Casts from __user to address-space-agnostic in amd64 and i386
made explicit (__force added; in these places we pass userland pointer
to arch-specific code that handles kernel and userland pointers the
same way).
	csum_partial_copy_*() annotated properly

	this basically repeats the stuff done to fs/binfmt_aout.c for amd64
and sparc64 aout32.

	(no, it still doesn't fix sparc32-smp - just partial compile
fixes ;-/)

We have a fun situation with read_descriptor_t - all its instances end
up passed to some actor; these actors use desc->buf as their private
data; there are 5 of them and they expect resp:

        struct lo_read_data *
        struct svc_rqst *
        struct file *
        struct rpc_xprt *
        char __user *

IOW, there is no type safety whatsoever; the field is essentially untyped,
we rely on the fact that actor is chosen by the same code that sets ->buf
and expect it to put something of the right type there.

Right now desc->buf is declared as char __user *.  Moreover, the last
argument of ->sendfile() (what should be stored in ->buf) is void __user *,
even though it's actually _never_ a userland pointer.

If nothing else, ->sendfile() should take void * instead; that alone removes
a bunch of bogus warnings.  I went further and replaced desc->buf with a
union of void * and char __user *.

Rename PCDP_TABLE_GUID back to HCDP_TABLE_GUID to get the file to compile
again.  This change is against current 2.6 BK and is under
