Handle going-away devices.

This patch fixes an incorrect MCA check as well as a leak on probe
failure in at1700.

This patch frees the netdev on failure in mc32_probe in 3c527.

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.

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.

proc_resetdevice is called with dev->serialize held.
usb_reset_device takes dev->serialize and then calls
__usb_reset_device.  To avoid deadlock, proc_resetdevice
should call __usb_reset_device directly.

The attached patch enables the pwc driver included with kernel 2.6.7-rc2

It also removes the warnings during compilation.
However, note that I blindly duplicated the release approach used by
other usb camera drivers, replacing the current no-op.

The driver works for me with a Logitech QuickCam Notebook Pro and
GnomeMeeting.

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

When handling FBIOPUTCMAP_SPARC, sbusfb fails to initialize cmap.transp,
which quickly leads to an oops when fb_set_cmap() dereferences it.

First encountered in Aurora Wombat kernels and seems to afflict mainline
as well. Patch is against 2.6.7-rc2. xorg still fails to actually get
anything to display on my CG6, but at least it no longer oopses the kernel.

This entry in the DMI blacklist table is missing it's NO_MATCH
tags, which means the struct gets padded instead of filled with
the desired NO_MATCH data which is {255, NULL}

Usually not fatal it seems, but there have been numerous cases
in Red Hat bugzilla where this did get tripped up, and caused
an immediate reset on these boards. Not fun to track down.

Adds a dummy flush_tlb_page_nohash() called by ptep_set_access_bits(),

ARGH. Missed one file. Here is an additional patch (missed tlbflush.h patch)

Sorry.

This adds the definiction of flush_tlb_page_nohash() that was missing
from the previous patch fixing SW-TLB loaded PPCs

The recent introduction of ptep_set_access_flags() with the optimisation
of not flushing the TLB unfortunately broke ppc32 CPUs with no hash
table.

The data access exception code path in assembly for these doesn't
properly deal with the case where the TLB entry is present with the
wrong PAGE_RW and will just call do_page_fault again instead of just
replacing the TLB entry.

Fixing the asm code for all the different CPU types affected (yah,
embedded PPCs all have different MMUs =P) is painful and need testing I
can't do at the moment, so here's a fix that will just flush the TLB
page when changing the access flags on non-hash based machines.  Please
apply.

The scheduler changes had another thing missing: the appreciation of
sync wakeups.  (I had this in one of the earlier sched-domains cleanup
patches before but it got lost in the shuffle.)

When a sync waker is waking, we should subtract its load from the
current load - it will schedule away for sure in the near future. 
That's what the "sync" bit means.

This change is necessary because with the sched-domains balancer we have
a much more sensitive cpu-load estimator, and in this particular context
of try_to_wake_up() the sync waker's effect will always be part of the
load.  Patch against your patch attached. 

In my testing there's an additional increase in bw_pipe numbers on a
dual P2 box, it went from 110-120 MB/sec to 120-130 MB/sec.

watchdog.h is using __u8 and __u32 from linux/types.h, so it needs to
