device structure
Link the net_device structure of the wireless part to the
corresponding device structure.
Without this, the sysfs node for this net_device would not have
'device' link.

It is obviously wrong to use an enum in a little endian struct,

The recent patch named:
[SCSI] gdth: !use_sg cleanup and use of scsi accessors
has done a bad job in handling internal commands issued by gdth_execute().
Internal commands are issued with device gdth_cmd_str ready made directly
to the card, without any mapping or translations of scsi commands. So here
I added a gdth_cmd_str pointer to the gdth_cmndinfo private structure which
is then copied directly to host.
following this patch is a cleanup that removes the home cooked accessors
and reverts them to regular scsi_cmnd accessors. Since they are not used
anymore. After review maybe the 2 patches should be squashed together.
FIXME: There is still a problem with gdth_get_info(). as reported there
is a WARN_ON trigerd in dma_free_coherent() when doing:
$ cat /proc/sys/gdth/0

gdth_exit would first remove all cards then stop the timer
and would not sync with the timer function. This caused a crash
in gdth_timer() when module was unloaded.
So del_timer_sync the timer before we delete the cards.
also the reboot notifier function would crash. So clean
that up and fix the crashes.

At present, we have a situation where a context with no owner is
re-scheduled by spu_forget:
Thread 1: reading regs file Thread 2: context owner
spu_forget()
- ctx->owner = NULL
- set SPU_SCHED_WAS_ACTIVE
spu_acquire_saved()
- context is in saved state
spu_release_saved()
- SPU_SCHED_WAS_ACTIVE is set,
so spu_activate() the context,
which now has no owner
In spu_forget(), we shouldn't be requesting a re-schedule by setting
SPU_SCHED_WAS_ACTIVE. This change removes the set_bit in spu_forget(),
so that spu_release_saved() doesn't reinsert this destroyed context on
to the run queue.

Properly add parens around the macro argument. This is not needed by
the kernel but the macro is exported to userspace, so it shouldn't
make any assumptions.
Also use NF_VERDICT_BITS instead of NF_VERDICT_QBTIS for the left-shift
since thats whats logically correct.

Iff the parent has TIF_DEBUG set, _and_ clone_flags includes
CLONE_PTRACE we should set the TIF_DEBUG flag for the child and
increment the ocd refcount. Otherwise, the TIF_DEBUG flag must be
unset.
Currently, the child inherits TIF_DEBUG from the parent before
copy_thread is called, so TIF_DEBUG may be already be set before we
determine whether the child is supposed to inherit debugging
capabilities from the parent or not. This means that ocd_enable()
won't increment the refcount, because TIF_DEBUG is already set, and
that TIF_DEBUG will be set for processes that aren't being debugged.
This leads to a refcounting asymmetry, which may show up as
------------[ cut here ]------------
Badness at arch/avr32/kernel/ocd.c:73
PC is at ocd_disable+0x34/0x60
LR is at put_lock_stats+0xa/0x20
as reported by David Brownell. Happens when strace'ing a process that
forks a new child process, e.g. "strace mount -tjffs2 mtd1 /mnt", and
subsequently killing the child process (e.g. "umount /mnt".)

Four tunnel drivers (ip_gre, ipip, ip6_tunnel and sit) can receive a
pre-defined name for a device from the userspace. Since these drivers
call the register_netdevice() (rtnl_lock, is held), which does _not_
generate the device's name, this name may contain a '%' character.
Not sure how bad is this to have a device with a '%' in its name, but
all the other places either use the register_netdev(), which call the
dev_alloc_name(), or explicitly call the dev_alloc_name() before
registering, i.e. do not allow for such names.
This had to be prior to the commit 34cc7b, but I forgot to number the
patches and this one got lost, sorry.

We have a small window where a spu context may be destroyed while
we're servicing a page fault (from another thread) to the context's
problem state mapping.
After we up_read() the mmap_sem, it's possible that the context is
destroyed by its owning thread, and so the later references to ctx
are invalid. This can maifest as a deadlock on the (now free()-ed)
context state mutex.
This change adds a reference to the context before we release the
mmap_sem, so that the context cannot be destroyed.

To make sure the procfs visibility occurs after the ->proc_fs ops are
setup, use proc_net_fops_create() and proc_net_remove().
This also fixes an OOPS after module unload in that the name string
for remove was wrong, so it wouldn't actually be removed. That bug
was introduced by commit 61145aa1a12401ac71bcc450a58c773dd6e2bfb9

This bug did bite at least one user, who did have to resort to rebooting
the system after an "ifconfig eth0 127.0.0.1" typo.
Deleting the address and adding a new is a less intrusive workaround.
But I still beleive this is a bug that should be fixed. Some way or
another.
Another possibility would be to remove the scope mangling based on
address. This will always be incomplete (are 127/8 the only address
space with host scope requirements?)
We set the scope to RT_SCOPE_HOST if an IPv4 interface is configured
with a loopback address (127/8). The scope is never reset, and will
remain set to RT_SCOPE_HOST after changing the address. This patch
resets the scope if the address is changed again, to restore normal
functionality.

Some parts of the kernel now do things like do *_user() accesses while
set_fs(KERNEL_DS) that fault on purpose.
See, for example, the code added by changeset
a0c1e9073ef7428a14309cba010633a6cd6719ea ("futex: runtime enable pi
and robust functionality").
That trips up the ASI sanity checking we make in do_kernel_fault().
Just remove it for now. Maybe we can add it back later with an added
conditional which looks at the current get_fs() value.

In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that
involved converting !x & y to !(x & y). The code below shows the same
pattern, and thus should perhaps be fixed in the same way.
This is not tested and clearly changes the semantics, so it is only
something to consider.
The semantic patch that makes this change is as follows:
