19bb3506e2 [BRIDGE]: Unaligned access when comparing ethernet addresses
compare_ether_addr() implicitly requires that the addresses
passed are 2-bytes aligned in memory.

This is not true for br_stp_change_bridge_id() and
br_stp_recalculate_bridge_id() in which one of the addresses
is unsigned char *, and thus may not be 2-bytes aligned.

0304ff8a2d [SCTP]: Unmap v4mapped addresses during SCTP_BINDX_REM_ADDR operation.
During the sctp_bindx() call to add additional addresses to the
endpoint, any v4mapped addresses are converted and stored as regular
v4 addresses.  However, when trying to remove these addresses, the
v4mapped addresses are not converted and the operation fails.  This
patch unmaps the addresses on during the remove operation as well.

ea2bc483ff [SCTP]: Fix assertion (!atomic_read(&sk->sk_rmem_alloc)) failed message
In current implementation, LKSCTP does receive buffer accounting for
data in sctp_receive_queue and pd_lobby. However, LKSCTP don't do
accounting for data in frag_list when data is fragmented. In addition,
LKSCTP doesn't do accounting for data in reasm and lobby queue in
structure sctp_ulpq.
When there are date in these queue, assertion failed message is printed
in inet_sock_destruct because sk_rmem_alloc of oldsk does not become 0
when socket is destroyed.

c2ecba7171 [NET]: Set a separate lockdep class for neighbour table's proxy_queue
Otherwise the following calltrace will lead to a wrong
lockdep warning:

  neigh_proxy_process()
    `- lock(neigh_table->proxy_queue.lock);
  arp_redo /* via tbl->proxy_redo */
  arp_process
  neigh_event_ns
  neigh_update
  skb_queue_purge
    `- lock(neighbor->arp_queue.lock);

This is not a deadlock actually, as neighbor table's proxy_queue
and the neighbor's arp_queue are different queues.

Lockdep thinks there is a deadlock as both queues are initialized
with skb_queue_head_init() and thus have a common class.

5a6d41b32a NFS: Ensure PG_writeback is cleared when writeback fails
If the writebacks are cancelled via nfs_cancel_dirty_list, or due to the
memory allocation failing in nfs_flush_one/nfs_flush_multi, then we must
ensure that the PG_writeback flag is cleared.

Also ensure that we actually own the PG_writeback flag whenever we
schedule a new writeback by making nfs_set_page_writeback() return the
value of test_set_page_writeback().
The PG_writeback page flag ends up replacing the functionality of the
PG_FLUSHING nfs_page flag, so we rip that out too.

6e3b2bbb19 [SCSI] 3w-xxxx: fix oops caused by incorrect REQUEST_SENSE handling
3w-xxxx emulates a REQUEST_SENSE response by simply returning nothing.
Unfortunately, it's assuming that the REQUEST_SENSE command is
implemented with use_sg == 0, which is no longer the case.  The oops
occurs because it's clearing the scatterlist in request_buffer instead
of the memory region.

This is fixed by using tw_transfer_internal() to transfer correctly to
the scatterlist.

d791d413fd DVB: dvb-usb-remote - fix oops when changing keymap
DVB USB remotes do not support changing keycode maps but set
input_dev->keycodesize and input_dev->keycodemax without setting
input_dev->keycode. This causes kernel oops when user tries to
look up (or change) current keymap.

While the proper fix would be to make remotes handle keymap changes
we'll just remove keycodemax and keycodesize initialization so
EVIOCGKEYCODE and EVIOCSKEYCODE will simply return -EINVAL.

279e172a58 [VLAN]: Allow VLAN interface on top of bridge interface
When a VLAN interface is created on top of a bridge interface and 
netfilter is enabled to see the bridged packets, the packets can be 
corrupted when passing through the netfilter code. This is caused by the 
VLAN driver not setting the 'protocol' and 'nh' members of the sk_buff 
structure. In general, this is no problem as the VLAN interface is mostly 
connected to a physical ethernet interface which does not use the 
'protocol' and 'nh' members. For a bridge interface, however, these 
members do matter.

c3724b129b [PATCH] autofs4: fix race in unhashed dentry code
Commit f50b6f8691 introduced a race in
autofs4 between autofs_lookup_unhashed() and autofs_dentry_release().

autofs_dentry_release() ends up clearing the ->dentry and ->inode members
of autofs_info before removing it from the rehash list.  The list is
protected by the rehash lock in both functions, but since
autofs_dentry_release() starts tearing the autofs_info struct down before
removing it from the list, autofs_lookup_unhashed() can get a autofs_info
with a NULL dentry.

This patch moves the clearing of ->dentry and ->inode after the removal
from the rehash list.

1d51c69fb6 [SPARC]: avoid CHILD_MAX and OPEN_MAX constants
I don't figure anyone really cares about SunOS syscall emulation, and I
certainly don't.  But I'm getting rid of uses of the OPEN_MAX and CHILD_MAX
compile-time constant, and these are almost the only ones.  OPEN_MAX is a
bogus constant with no meaning about anything.  The RLIMIT_NOFILE resource
limit is what sysconf (_SC_OPEN_MAX) actually wants to return.

The CHILD_MAX cases weren't actually using anything I want to get rid of,
but I noticed that they are there and are wrong too.  The CHILD_MAX value
is not really unlimited as a -1 return from sysconf indicates.  The
RLIMIT_NPROC resource limit is what sysconf (_SC_CHILD_MAX) wants to return.

2f3a2efd85 [SPARC64]: Fix SBUS IOMMU allocation code.
There are several IOMMU allocator bugs.  Instead of trying to fix this
overly complicated code, just mirror the PCI IOMMU arena allocator
which is very stable and well stress tested.

I tried to make the code as identical as possible so we can switch
sun4u PCI and SBUS over to a common piece of IOMMU code.  All that
will be need are two callbacks, one to do a full IOMMU flush and one
to do a streaming buffer flush.

This patch gets rid of a lot of hangs and mysterious crashes on SBUS
sparc64 systems, at least for me.
