Eliminate more __must_check madness.
The return code from device_for_each_child() depends on the values

returns zero, it's utterly pointless to check the return code from
device_for_each_child().
The only code which knows if the return value should be checked is
the caller itself, so forcing the return code to always be checked
is silly. Hence, remove the __must_check annotation.

[DCCP]: Fix Oops in DCCPv6
I think I got the cause for the Oops observed in
http://www.mail-archive.com/dccp@vger.kernel.org/msg00578.html
The problem is always with applications listening on PF_INET6 sockets. Apart
from the mentioned oops, I observed another one one, triggered at irregular
intervals via timer interrupt:
The latter function is the problem and is also the last function to be called
in said kernel panic.
In any case, there is a real problem with allocating the right request_sock
which is what this patch tackles.
It fixes the following problem:
- application listens on PF_INET6
- DCCPv4 packet comes in, is handed over to dccp_v4_do_rcv, from there
to dccp_v4_conn_request
Now: socket is PF_INET6, packet is IPv4. The following code then furnishes the
connection with IPv6 - request_sock operations:
req = reqsk_alloc(sk->sk_prot->rsk_prot);
The first problem is that all further incoming packets will get a Reset since
the connection can not be looked up.
The second problem is worse:
--> reqsk_alloc is called instead of inet6_reqsk_alloc
--> consequently inet6_rsk_offset is never set (dangling pointer)
--> the request_sock_ops are nevertheless still dccp6_request_ops
--> destructor is called via reqsk_free
--> dccp_v6_reqsk_destructor tries to free random memory location (inet6_rsk_offset not set)
--> panic
I have tested this for a while, DCCP sockets are now handled correctly in all
three scenarios (v4/v6 only/v4-mapped).
Commiter note: I've added the dccp_request_sock_ops forward declaration to keep
the tree building and to reduce the size of the patch for 2.6.19,
later I'll move the functions to the top of the affected source
code to match what we have in the TCP counterpart, where this
problem hasn't existed in the first place, dumb me not to have
done the same thing on DCCP land 8)

Use valid values for ICH8 map_db. With the old values, when the
controller was in Native mode, and SCC was 1 (drives configured for
IDE), any drive plugged into a slave port was not recognized. For
Combined Mode (and SCC is still 1), 2 is a value value for MAP.map_value,
and needs to be recognized.

Found the problem, I believe: an object lesson in the need for great
caution using ++.
Since the ++ is used as post-increment, the increment is not included
in free_index, and so the added line effectively reverts the
increment. The produced_index side has an analagous bug.
The following change corrects this:
The recent commit 751ae21c6cd1493e3d0a4935b08fb298b9d89773 introduced
a bug in the producer/consumer index calculation in the ibmveth driver
- incautious use of the post-increment ++ operator resulted in an
increment being immediately reverted. This patch corrects the logic.
Without this patch, the driver oopses almost immediately after
activation on at least some machines.

[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes
changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

The reason sky2 driver was locking up on transmit on the Yukon-FE chipset
is that it was misconfiguring the internal RAM buffer so the transmitter
and receiver were sharing the same space.
The code assumed there was 16K of RAM on Yukon-FE (taken from vendor driver
sk98lin which is even more f*cked up on this). Then it assigned based on that.
The giveaway was that the registers would only hold 9bits so both RX/TX
had 0..1ff for space. It is a wonder it worked at all!
This patch addresses this, and fixes an easily reproducible hang on Transmit.
Only the Yukon-FE chip is Marvell 88E803X (10/100 only) are affected.

[PATCH] x86-64: Revert timer routing behaviour back to 2.6.16 state
By default route the 8254 over the 8259 and only disable
it on ATI boards where this causes double timer interrupts.
This should unbreak some Nvidia boards where the timer doesn't
seem to tick of it isn't enabled in the 8259. At least one
VIA board also seemed to have a little trouble with the disabled
8259.
For 2.6.20 we'll try both dynamically without black listing, but I think
for .19 this is the safer approach because it has been already well tested
in earlier kernels. This also makes the x86-64 behaviour the same
as i386.
Command line options can change all this of course.

o Now all the vsyscall related sections are placed after data and after
that mostly init data sections are placed. To avoid physical overlap

- Place vsyscall sections also in data phdrs instead of user
- move vsyscal sections after init data in bss.
- create another phdrs say data.init and move all the sections

[PATCH] x86-64: Put more than one cpu in TARGET_CPUS
TARGET_CPUS is the default irq routing poicy. It specifies which cpus the
kernel should aim an irq at. In physflat delivery mode we can route an irq to
a single cpu. But that doesn't mean our default policy should only be a
single cpu is allowed.
By allowing the irq routing code to select from multiple cpus this enables
systems with more irqs then we can service on a single processor to actually
work.
I just audited and tested the code and irqbalance doesn't care, and the
io_apic.c doesn't care if we have extra cpus in the mask. Everything will use
or assume we are using the lowest numbered cpu in the mask if we can't use
them all.
So this should result in no behavior changes except on systems that need it.
Thanks for YH Lu for spotting this problem in his testing.

While reviewing YH's patch I also noticed that this function was missing
