Get rid of warning in case of race with ring full and lockless
tx on the skge driver. It is possible to be in the transmit
routine with no available slots and already stopped.

The CSR contains garbage after a coldboot on RS/6000.
One some systems (like my 44p 270) the MAC address is all FF,
on others (like my B50) it is ff:ff:ff:fd:ff:6b.
It can eventually be fixed by loading pcnet32, set the interface
into the UP state, rmmod pcnet32 and load it again. But this worked
only on the 270.
Only netbooting after a cold start provides the correct MAC address
via prom and CSR. This makes it very unreliable.
I dont know why the MAC is stored in two different places. Remove
the special case for powerpc, which was added in early 2.4 development.

drivers/char/watchdog/mpcore_wdt.c write function contains a check for
(ppos != &file->f_pos). Such check used to make sense when a pointer to
file->f_pos was handed by vfs_write(), not a copy of it as it stands
now.

There is a double free in the scsi scan code if a LLDD's slave_alloc()
call fails. There is a direct call to scsi_free_queue and then the
following put_device calls the release function, which also frees the
queue.
Remove the redundant scsi_free_queue.

In e1000_free_desc_rings, zero-out pointers after the memory they
point to is freed. The test rings are static and get re-used, and
failures during subsequent test setups can cause e1000_free_desc_rings
to get called with dirty pointers. Dirty pointers can cause oopses
or crashes...

This reverts commit 1b0997f561bf46689cc6e0903f342e9bf2506bf1, which in
turn reverted 34ea80ec6a02ad02e6b9c75c478c18e5880d6713 (which is thus
re-instated).
Quoth James Bottomley:
"All it's doing is deferring the device_put() from the
scsi_put_command() to after the scsi_run_queue(), which doesn't fix
the sleep while atomic problem of the device release method. In both
cases we still get the semaphore in atomic context problem which is
caused by scsi_reap_target() doing a device_del(), which I assumed
(wrongly) was valid from atomic context."

The raid5 stripe cache was recently changed from fixed size (NR_STRIPES) to
variable size (conf->max_nr_stripes). However there are two places that still
use the constant and as a result, reducing the size of the stripe cache can
result in a deadlock.
