      af_packet: de-inline some helper functions · eea49cc9
      Olof Johansson authored 
      This popped some compiler errors due to mismatched prototypes. Just
remove most manual inlines, the compiler should be able to figure out
what makes sense to inline and not.

      net: Add back alignment for size for __alloc_skb · bc417e30
      Tony Lindgren authored 
      Commit 87fb4b7b (net: more
accurate skb truesize) changed the alignment of size. This
can cause problems at least on some machines with NFS root:

Here PC is at __alloc_skb and &shinfo->dataref is unaligned because
skb->end can be unaligned without this patch.

As explained by Eric Dumazet <eric.dumazet@gmail.com>, this happens
only with SLOB, and not with SLAB or SLUB:

      net: add missing bh_unlock_sock() calls · 918eb399
      Eric Dumazet authored 
      Simon Kirby reported lockdep warnings and following messages :

[104661.897577] huh, entered softirq 3 NET_RX ffffffff81613740
preempt_count 00000101, exited with 00000102?

[104661.923653] huh, entered softirq 3 NET_RX ffffffff81613740
preempt_count 00000101, exited with 00000102?

Problem comes from commit 0e734419
(ipv4: Use inet_csk_route_child_sock() in DCCP and TCP.)

If inet_csk_route_child_sock() returns NULL, we should release socket
lock before freeing it.

Another lock imbalance exists if __inet_inherit_port() returns an error
since commit 093d2823 ( tproxy: fix hash locking issue when using
port redirection in __inet_inherit_port()) a backport is also needed for
>= 2.6.37 kernels.

      l2tp: fix race in l2tp_recv_dequeue() · e2e210c0
      Eric Dumazet authored 
      Misha Labjuk reported panics occurring in l2tp_recv_dequeue()

If we release reorder_q.lock, we must not keep a dangling pointer (tmp),
since another thread could manipulate reorder_q.

Instead we must restart the scan at beginning of list.

      edac: Only build sb_edac on 64-bit · f04c045f
      Josh Boyer authored 
      The sb_edac driver is marginally useful on a 32-bit kernel, and
currently has 64-bit divide compile errors when building that config.
For now, make this build on only for 64-bit kernels.

      Linus Torvalds authored 
      This reverts commit 144060fe.

It causes a resume regression for Andi on his Acer Aspire 1830T post
3.1.  The screen just stays black after wakeup.

Also, it really looks like the wrong way to suspend and resume perf
events: I think they should be done as part of the CPU suspend and
resume, rather than as a notifier that does smp_call_function().
