In commit 4e8a5201506423e0241202de1349422af4260296 ("[PKT_SCHED] netem:
Orphan SKB when adding to queue.") Davem mistakenly also included a
temporary diff in his tree that disabled the pci_fixup_video VGA quirk,
which broke sparc64.
This reverts that part of the commit. Sayeth Davem:
"Greg KH has a patch coming to you soon which will move that VGA code
back into x86/x86_64/IA64 specific areas and will fix the sparc64
problem properly."
Special thanks to Claudio Martins <ctpm@ist.utl.pt> for noticing the
error in the first place.

Eliminate more __must_check madness.
The return code from device_for_each_child() depends on the values
which the helper function returns. If the helper function always
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.

Otherwise we get a ton of unaligned exceptions, for cases such
as compat_sys_msgrcv() which go:
p = compat_alloc_user_space(second + sizeof(struct msgbuf));
and here 'second' can for example be an arbitrary odd value.

The networking emulator can queue SKBs for a very long
time, so if you're using netem on the sender side for
large bandwidth/delay product testing, the SKB socket
send queue sizes become artificially larger.
Correct this by calling skb_orphan() in netem_enqueue().

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:
run_timer_softirq -> dccp_keepalive_timer
-> inet_csk_reqsk_queue_prune
-> reqsk_free
-> dccp_v6_reqsk_destructor
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)

The current implementation uses a sequence of a cacheflush and a copy.
This is racy in case of a multithreaded debuggee and renders GDB
virtually unusable.
Aside this fixes a performance hog rendering access to /proc/cmdline very
slow and resulting in a enough cache stalls for the 34K AP/SP programming
model to make the bare metal code on the non-Linux VPE miss RT deadlines.

CCISS was producing warnings about shifts being greater than the size of
the type and pointers being of incompatible type. Turns out this is
because it's calling do_div on a 32-bit quantity. Upon further
investigation, the sector_t total_size is being assigned to an int, and
then we're calling do_div on that int. Obviously, sector_div is called for
here, and I took the chance to refactor the code a little.

Mistyped an ifdef CONFIG_CPUSETS - fixed.
I doubt that anyone ever noticed. The impact of this typo was
that if someone:
1) was using MPOL_BIND to force off node allocations
2) while using cpusets to constrain memory placement
3) when that cpuset was migrating that jobs memory
4) while the tasks in that job were actively forking
then there was a rare chance that future allocations using
that MPOL_BIND policy would be node local, not off node.

The zonelist may contain zones of nodes that have not been bootstrapped and
we will oops if we try to allocate from those zones. So check if the node
information for the slab and the node have been setup before attempting an
allocation. If it has not been setup then skip that zone.
Usually we will not encounter this situation since the slab bootstrap code
avoids falling back before we have setup the respective nodes but we seem
to have a special needs for pppc.

The change from __setup() to module_param_named() requires users to prefix

This patch re-adds the __setup() additionally to the module_param_named().
Usually it would make sense getting rid of such an obsolete __setup() at
some time, but considering that drivers/ide/ is slowly approaching a RIP
status it's already implicitely scheduled for removal.
