Expand CONFIG_DEBUG_LIST to several other list operations

debugging code in them to do some basic validation of the list entries.
However, "list_del_init()" and "list_move[_tail]()" ended up avoiding

IB/qib: Prevent double completions after a timeout or RNR error
There is a double completion associated with error handling for RC QPs.
The sequence is:
- The do_rc_ack() routine fields an RNR nack and there are 0
rnr_retries configured on the QP.
- qib_error_qp() stops the pending timer
- qib_rc_send_complete() is called from sdma_complete()
- qib_rc_send_complete() starts the timer because the msb of the psn
just completed says an ack is needed.
- a bunch of flushes occur as ipoib posts WQEs to an error'ed QP
- rc_timeout() calls qib_restart_rc()
- qib_restart_rc() calls qib_send_complete() with a
IB_WC_RETRY_EXC_ERR on a wqe that has already been completed in the
past

arrive.

netfilter: tproxy: do not assign timewait sockets to skb->sk
Assigning a socket in timewait state to skb->sk can trigger
kernel oops, e.g. in nfnetlink_log, which does:
if (skb->sk) {
read_lock_bh(&skb->sk->sk_callback_lock);
if (skb->sk->sk_socket && skb->sk->sk_socket->file) ...
in the timewait case, accessing sk->sk_callback_lock and sk->sk_socket
is invalid.
Either all of these spots will need to add a test for sk->sk_state != TCP_TIME_WAIT,
or xt_TPROXY must not assign a timewait socket to skb->sk.
This does the latter.
If a TW socket is found, assign the tproxy nfmark, but skip the skb->sk assignment,
thus mimicking behaviour of a '-m socket .. -j MARK/ACCEPT' re-routing rule.
The 'SYN to TW socket' case is left unchanged -- we try to redirect to the

It turns out that the change breaks a bunch of kernel code that opens

Because strict checking for read-only opens of block devices was not
done before this, the code that opens the devices was opening them

be _after_ dropping RCU, since the dentry isn't necessarily stable

So complete the code movement in that commit, and move the BUG_ON() into
do_follow_link() too. This means that we need to pass in 'inode' as an
argument (just for this one use), but that's a small thing. And
eventually we may be confident enough in our path lookup that we can
just remove the BUG_ON() and the unnecessary inode argument.

Remove it and use the kernels standard memcmp() implementation.
This also goes part of the way to fixing a regression caused by commit
ea61bc461d09e8d331a307916530aaae808c72a2 ("m68k/m68knommu: merge MMU and
non-MMU string.h"), which breaks non-coldfire non-mmu builds (which is
the 68x328 and 68360 families). They currently have no memcmp() function
defined, since there is none in the m68knommu/lib functions.

thp: prevent hugepages during args/env copying into the user stack
Transparent hugepages can only be created if rmap is fully
functional. So we must prevent hugepages to be created while
is_vma_temporary_stack() is true.
This also optmizes away some harmless but unnecessary setting of
khugepaged_scan.address and it switches some BUG_ON to VM_BUG_ON.

sparc64: Fix NMI startup bug which also breaks perf.
Doing NMI startup as an early initcall doesn't work because we need
to have SMP started up by then.
So we'd only NMI startup one cpu, which causes perf PMU grab to
BUG because the nmi_active count isn't what it's supposed to be.
This also points out that we don't have proper CPU up/down notifiers
for the NMI code which will need to be fixed at some point.

spi/pxa2xx pci: fix the release - remove race
Right now the platform device and its platform data is included in one big
struct which requires its custom ->release function. The problem with the
release function within the driver is that it might be called after the
driver was removed because someone was holding a reference to it and it
was not called right after platform_device_unregister(). So we also free
the platform device memory to which one might hold a reference.
This patch uses the normal pdev functions so this kind of race does not
occur.

isdn: hisax: Use l2headersize() instead of dup (and buggy) func.
There was a bug in my commit

One of the l2->flag checks is wrong.
Even worse it turns out I'm duplicating an existing function,
so use that instead.
