This patch fixes a false-positive from debug_smp_processor_id().

The processor ID is only used to look up crypto_tfm objects.
Any processor ID is acceptable here as long as it is one that is
iterated on by for_each_cpu().

Change operations on rif_lock from spin_{un}lock_bh to
spin_{un}lock_irq{save,restore} equivalents.  Some of the

The DM9000 driver is responding to ioctl() calls it should not be. This
can cause problems with the wireless tools incorrectly indentifying the
device as wireless capable, and crashing under certain operations.

This patch also moves the version printk() to the init call, so that
you only get it once for multiple devices, and to show it is loaded
if there are no defined dm9000s

Fix DM9000 driver usage of spinlocks, which mainly came to light
when running a kernel with spinlock debugging. These come down to:

1) Un-initialised spin lock

2) Several cases of using  spin_xxx(lock) and not spin_xxx(&lock)

3) move the locking around the phy reg for read/write to only
   keep the lock when actually reading or writing to the phy.

... otherwise we might try to load a bitmap from an array which hasn't one.

The bug is that if you create an array with an internal bitmap, shut it down,
and then create an array with the same md device, the md drive will assume it
should have a bitmap too.  As the array can be created with a different md
device, it is mostly an inconvenience.  I'm pretty sure there is no risk of
data corruption.

Down the road we want to eliminate the use of the global kernel lock entirely
from the NFS client.  To do this, we need to protect the fields in the
nfs_inode structure adequately.  Start by serializing updates to the
"cache_validity" field.

Note this change addresses an SMP hang found by njw@osdl.org, where processes
deadlock because nfs_end_data_update and nfs_revalidate_mapping update the
"cache_validity" field without proper serialization.

Test plan:
 Millions of fsx ops on SMP clients.  Run Nick Wilson's breaknfs program on
 large SMP clients.

Introduce atomic bitops to manipulate the bits in the nfs_inode structure's
"flags" field.

Using bitops means we can use a generic wait_on_bit call instead of an ad hoc
locking scheme in fs/nfs/inode.c, so we can remove the "nfs_i_wait" field from
nfs_inode at the same time.

The other new flags field will continue to use bitmask and logic AND and OR.
This permits several flags to be set at the same time efficiently.  The
following patch adds a spin lock to protect these flags, and this spin lock
will later cover other fields in the nfs_inode structure, amortizing the cost
of using this type of serialization.

Certain bits in nfsi->flags can be manipulated with atomic bitops, and some
