In light of the recent discussion about sk_buff, I think we need
the following patch for dst_entry.  This adds a memory barrier
before dst_release drops the refcnt, and a read memory barrier
before dst_destroy starts destroying the entry.

Also kill kfree_skb_fast(), that is a relic from fast switching
which was killed off years ago.

The bug is that in the case where we do the atomic_read()
optimization, we need to make sure that reads of skb state
later in __kfree_skb() processing (particularly the skb->list
BUG check) are not reordered to occur before the counter
read by the cpu.

Thanks to Olaf Kirch and Anton Blanchard for discovering
and helping fix this bug.

- Fix capacitive coupling detection by reading the correct offset in sram
- Add support for different signal pre-emphasis on 5704S (used in some blade
servers)
- Improve 5704S link parallel detection. When autonegotiation fails, we only
detect link-up if we have PCS_SYNC and we are not receiving config code
words. This will prevent false link-up when only the rx cable is attached.

Netfilter conntrack can defragment locally generated
packets before they hit ip_fragment().  In this case
the fragments have skb->dst set already, so we have to
release that existing reference before overwriting
skb->dst.

This is the third of 4 patches which factor out common code in
the ARM exception entry assembly code, aiming towards a reduction
in the size of the changes required here for SMP support.  These
patches are low impact, and will be merged over the coarse of the
next few days.

This patch addresses the code handling exception entry from user
modes.

Thanks to Russell King for some excellent debugging.

This patch addresses the code handling exception entry from
invalid (irq, fiq, abort) modes.  However, in converting to a
macro, a minor bug has been fixed which would merely cause a
misleading register dump.

The special case for the Sharp LH processors is unnecessary.  A macro
override makes it cleaner and concentrates the change where it ought
to be.  The default in include/asm-arm/numnodes.h means that only
platforms that care to change the default need to do anything.
