Fix bug in bnx2_interrupt() that caused an unnecessary register read.
The BNX2_PCICFG_MISC_STATUS should only be read when the status tag
has not changed.

Add prefetch of the status block in bnx2_msi() similar to tg3_msi().
The status block is not touched in bnx2_msi() and prefetching it will
speed up bnx2_poll() that will run on the same CPU that received the
MSI.

Update version.

A UDP packet may contain extra data that needs to be trimmed off.
But when doing so, UDP forgets to fixup the skb checksum if CHECKSUM_HW
is being used.

I think this explains the case of a NFS receive using skge driver
causing 'udp hw checksum failures' when interacting with a crufty
settop box.

When we copy 32bit ->msg_control contents to kernel, we walk the same
userland data twice without sanity checks on the second pass.

Second version of this patch: the original broke with 64-bit arches
running 32-bit-compat-mode executables doing sendmsg() syscalls with
unaligned CMSG data areas

Another thing is that we use kmalloc() to allocate and sock_kfree_s()
to free afterwards; less serious, but also needs fixing.

ICH6 spec defines the PORT_ bits as:

PORT_ENABLED (R/W):

  0 = Disabled.  The port is in the off state and cannot detect any
  devices.

  1 = Enabled.  The port can transition between the on, partial, and
  slumber states and can detect devices.

PORT_PRESENT  (R/O)

  The status of this bit may change at any time.  This bit is cleared
  when the port is disabled via PORT_ENABLED.  This bit is not cleared upon
  surprise removal of a device.

So from a textual view it is not necessary that PORT_PRESENT _must_ be set,
especially if a device detection has to be done anyway.  And, in fact, this
is the view that ACER has been taken with its new Laptops (e.g.  Travelmate
4150).

And the definition of PORT_ENABLED / PORT_PRESENT is mixed up, btw.

With the previous commit that introduces the klist enhancements, we can
now re-do 2b7d6a8c again.

The problem is that klists claim to provide semantics for safe traversal of
lists which are being modified.  The failure case is when traversal of a
list causes element removal (a fairly common case).  The issue is that
although the list node is refcounted, if it is embedded in an object (which
is universally the case), then the object will be freed regardless of the
klist refcount leading to slab corruption because the klist iterator refers
to the prior element to get the next.

The solution is to make the klist take and release references to the
embedding object meaning that the embedding object won't be released until
the list relinquishes the reference to it.

(akpm: fast-track this because it's needed for the 2.6.13 scsi merge)
