Every time a new syscall gets added, a BUILD_BUG_ON in
arch/powerpc/platforms/cell/spu_callbacks.c gets triggered.
Since the addition of a new syscall is rather harmless,
the error should just be removed.
While we're here, add sys_tee to the list and add a comment
to systbl.S to remind people that there is another list
on powerpc.

The new i2c implementation for PowerMac has a regression that causes the
hardware to go out of state when probing non-existent devices. While
fixing that, I also found & fixed a couple of other corner cases. This
fixes booting with a pbbuttons version that scans the i2c bus for an LMU
controller among others. Tested on a dual G5 with thermal control (which
has heavy i2c activity) with no problem so far.

Turn on the DART already at 1GB. This is needed because of crippled
devices in some systems, i.e. Airport Extreme cards, only supporting
30-bit DMA addresses.
Otherwise, users with between 1 and 2GB of memory will need to manually
enable it with iommu=force, and that's no good.
Some simple performance tests show that there's a slight impact of
enabling DART, but it's in the 1-3% range (kernel build with disk I/O
as well as over NFS).
iommu=off can still be used for those who don't want to deal with the
overhead (and don't need it for any devices).

I've just realised that the RtNetlink code does not check the
permission for SIOCGIWENCODE and SIOCGIWENCODEEXT, which means that
any user can read the encryption keys. The fix is trivial and should
go in 2.6.17 alonside the two other patch I sent you last week.

The room for the names in bcm43xx_priv_wx_args[] are IFNAMSIZ long and
IFNAMSIZ is defined as 16, so the names in bcm43xx_priv_wx_args should
be 15 characters (16 including the trailing \0). This patch fixes that
for the "set_shortpreambl", "get_shortpreambl", "set_swencryption", and
"get_swencryption" private calls. Patch is against 2.6.17-rc1.

This fixes a spinlock recursion on receiving a reassoc request.
On reassoc, the softmac calls back into the driver. This results in a
driver lock recursion. This schedules the assoc workqueue, instead
of calling it directly.
Probably, we should defer the _whole_ management frame processing
to a tasklet or workqueue, because it does several callbacks into the driver.
That is dangerous.
This fix should go into linus's tree, before 2.6.17 is released, because it
is remote exploitable (DoS by crash).

2.6.17-rc1 changed the title for the entry CONFIG_NET_RADIO. I
personally disagree with this change and want it reverted. Patch for
2.6.17-rc1.
Rationale : WIRELESS_EXT is an invisible option. Therefore,
the only way for a user to enable it is via NET_RADIO. Some users need
to do that for out-of-tree drivers. Therefore it should be mentionned
in the title of the option.
Rationale2 : the option just below is called "Wireless
Extension API over RtNetlink". Some users may confuse this option for
the main "Wireless Extension" option. Therefore reverting this change
help disambiguate the relation between those two options.

Airo firmware versions >= 5.30.17 send re-association events to the
driver that are currently unrecognized, causing spurious disassociation
events to be sent to user space. Loss of sync due to scan requests also
results in disassociation events sent to user space. This patch traps
those two events; suppressing sync-loss on scan, and sending the correct
association event on re-association notifications.

Add some sanity checking. truesize should be at least sizeof(struct

seriously mangled and deserves a kernel log message.

But we can add checks to more spots over time.

for_each_cpu() actually iterates across all possible CPUs. We've had mistakes
in the past where people were using for_each_cpu() where they should have been
iterating across only online or present CPUs. This is inefficient and
possibly buggy.

future.

Patch from Lennert Buytenhek
The irq2gpio array was recently converted from an array of ints to an
array of chars (by patch 3368/1.) However, this array contains elements
that are -1, and on ARM, the char type is unsigned by default, so this
patch broke the GPIO check in ixp4xx_set_irq_type.
Change the 'char' to be a 'signed char' to fix this.
