The implementation is optimal for UltraSPARC-III and later.
It will work, however suboptimally, on UltraSPARC-II and
be treated as a NOP on UltraSPARC-I.
It is not worth code patching this thing as the highest cost
is the code space, and code patching cannot eliminate that.

Here's a much smaller patch to simply disable devfs from the build. If
this goes well, and there are no complaints for a few weeks, I'll resend
my big "devfs-die-die-die" series of patches that rip the whole thing

Sit tunnel logging is currently broken:

Apart from the broken IP address, MAC addresses are printed differently
for sit tunnels than for everything else.

Here is a simplified version of the patch to fix a bug in IPv6
multicasting. It:
1) adds existence check & EADDRINUSE error for regular joins
2) adds an exception for EADDRINUSE in the source-specific multicast
join (where a prior join is ok)
3) adds a missing/needed read_lock on sock_mc_list; would've raced
with destroying the socket on interface down without
4) adds a "leave group" in the (INCLUDE, empty) source filter case.
This frees unneeded socket buffer memory, but also prevents
an inappropriate interaction among the 8 socket options that
mess with this. Some would fail as if in the group when you
aren't really.
Item #4 had a locking bug in the last version of this patch; rather than
removing the idev->lock read lock only, I've simplified it to remove
all lock state in the path and treat it as a direct "leave group" call for
the (INCLUDE,empty) case it covers. Tested on an MP machine. :-)

Essentially netlink at the moment always reports a pid and sequence of 0
always for v6 route activities.
To understand the repurcassions of this look at:
http://lists.quagga.net/pipermail/quagga-dev/2005-June/003507.html
While fixing this, i took the liberty to resolve the outstanding issue
of IPV6 routes inserted via ioctls to have the correct pids as well.
This patch tries to behave as close as possible to the v4 routes i.e
maintains whatever PID the socket issuing the command owns as opposed to
the process. That made the patch a little bulky.
I have tested against both netlink derived utility to add/del routes as
well as ioctl derived one. The Quagga folks have tested against quagga.
This fixes the problem and so far hasnt been detected to introduce any
new issues.

Finally (phew!) this patch demonstrates how to adapt the adm1026 to
take advantage of the new callbacks, and the i2c-sysfs.h defined
structure/macros. Most of the other sensor/hwmon drivers could be
updated in the same way. The odd few exceptions (bmcsensors for
example) however might be better off with their own custom attribute
structure.

Based on the discussion about spufs attributes, this is my suggestion
for a more generic attribute file support that can be used by both
debugfs and spufs.
Simple attribute files behave similarly to sequential files from
a kernel programmers perspective in that a standard set of file
operations is provided and only an open operation needs to
be written that registers file specific get() and set() functions.
These operations are defined as
void foo_set(void *data, u64 val); and
u64 foo_get(void *data);
where data is the inode->u.generic_ip pointer of the file and the
operations just need to make send of that pointer. The infrastructure
makes sure this works correctly with concurrent access and partial
read calls.
A macro named DEFINE_SIMPLE_ATTRIBUTE is provided to further simplify
using the attributes.
This patch already contains the changes for debugfs to use attributes
for its internal file operations.

This patch is intended for your "driver" tree. It fixes several subtle
races in driver_detach() and device_release_driver() in the driver-model
core.
The major change is to use klist_remove() rather than klist_del() when
taking a device off its driver's list. There's no other way to guarantee
that the list pointers will be updated before some other driver binds to
the device. For this to work driver_detach() can't use a klist iterator,
so the loop over the devices must be written out in full. In addition the
patch protects against the possibility that, when a driver and a device
are unregistered at the same time, one may be unloaded from memory before
the other is finished using it.
