- wrong status caused early break out of nand_wait()
- removed the bogus status check in nand_wait() which
is a relict of the abandoned support for interrupted
erase.
- status check moved to the correct place in read_oob
- oob support for syndrom based ecc with strange layouts
- use given offset in the AUTOOOB based oob operations

This ugly hack was long overdue to die.
It was a way to print out Sparc interrupts in a more freindly format,
since IRQ numbers were arbitrary opaque 32-bit integers which vectored
into PIL levels. These 32-bit integers were not necessarily in the
0-->NR_IRQS range, but the PILs they vectored to were.
The idea now is that we will increase NR_IRQS a little bit and use a
virtual<-->real IRQ number mapping scheme similar to PowerPC.
That makes this IRQ printing hack irrelevant, and furthermore only a
handful of drivers actually used __irq_itoa() making it even less
useful.

o hotplug slots add
When the hot-added PCI device is p2p bridge, acpiphp calls
find_p2p_bridge() to add hotplug slots.
o hotplug slots remove
When the hot-removing PCI device is p2p bridge, acpiphp
calls cleanup_p2p_bridge() to remove hotplug slots.
o notify handler exchange
When the p2p bridge is added, acpiphp changes the notify
hanlder.
If no bridge device is inserted into the hotpluggable PCI
slot, acpiphp installs the notify handler for function.
After the p2p bridge hot-add, acpiphp has to install the
notify handler for bridge. Because, the role of the

The current stack treats NETIF_F_HW_CSUM and NETIF_F_NO_CSUM
identically so we test for them in quite a few places. For the sake
of brevity, I'm adding the macro NETIF_F_GEN_CSUM for these two. We
also test the disjunct of NETIF_F_IP_CSUM and the other two in various
places, for that purpose I've added NETIF_F_ALL_CSUM.

Herbert Xu pointed out that it is unsafe to call netif_tx_disable()
from LLTX drivers because it uses dev->xmit_lock to synchronize
whereas LLTX drivers use private locks.
Convert tg3 to non-LLTX to fix this issue. tg3 is a lockless driver
where hard_start_xmit and tx completion handling can run concurrently
under normal conditions. A tx_lock is only needed to prevent
netif_stop_queue and netif_wake_queue race condtions when the queue
is full.
So whether we use LLTX or non-LLTX, it makes practically no
difference.

Remove tx_lock where it is unnecessary. tg3 runs lockless and so it
requires interrupts to be disabled and sync'ed, netif_queue and NAPI
poll to be stopped before the device can be reconfigured. After
stopping everything, it is no longer necessary to get the tx_lock.

Use CPU native page size to determine various ring sizes. This allows
order-0 memory allocations on all systems.
Added check to limit the page size to 16K since that's the maximum rx
ring size that will be used. This will prevent using unnecessarily
large page sizes on some architectures with large page sizes.

In ppp_receive_nonmp_frame, we call pskb_may_pull(skb, skb->len) if the
tailroom is >= 124. This is pointless because this pskb_may_pull is only
needed if the skb is non-linear. However, if it is non-linear then the
tailroom would be zero.
So it can be safely removed.

The linearisation operation doesn't need to be super-optimised. So we can
replace __skb_linearize with __pskb_pull_tail which does the same thing but
is more general.
Also, most users of skb_linearize end up testing whether the skb is linear
or not so it helps to make skb_linearize do just that.
Some callers of skb_linearize also use it to copy cloned data, so it's
useful to have a new function skb_linearize_cow to copy the data if it's
either non-linear or cloned.
Last but not least, I've removed the gfp argument since nobody uses it
anymore. If it's ever needed we can easily add it back.

Various drivers use xmit_lock internally to synchronise with their
transmission routines. They do so without setting xmit_lock_owner.
This is fine as long as netpoll is not in use.
With netpoll it is possible for deadlocks to occur if xmit_lock_owner
isn't set. This is because if a printk occurs while xmit_lock is held
and xmit_lock_owner is not set can cause netpoll to attempt to take
xmit_lock recursively.
While it is possible to resolve this by getting netpoll to use
trylock, it is suboptimal because netpoll's sole objective is to
maximise the chance of getting the printk out on the wire. So
delaying or dropping the message is to be avoided as much as possible.
So the only alternative is to always set xmit_lock_owner. The
following patch does this by introducing the netif_tx_lock family of
functions that take care of setting/unsetting xmit_lock_owner.
I renamed xmit_lock to _xmit_lock to indicate that it should not be
used directly. I didn't provide irq versions of the netif_tx_lock
functions since xmit_lock is meant to be a BH-disabling lock.
This is pretty much a straight text substitution except for a small
bug fix in winbond. It currently uses
netif_stop_queue/spin_unlock_wait to stop transmission. This is
unsafe as an IRQ can potentially wake up the queue. So it is safer to
use netif_tx_disable.
The hamradio bits used spin_lock_irq but it is unnecessary as
xmit_lock must never be taken in an IRQ handler.

Add recovery logic when we suspect that the system is re-ordering
MMIOs. Re-ordered MMIOs to the send mailbox can cause bogus tx
completions and hit BUG_ON() in the tx completion path.
tg3 already has logic to handle re-ordered MMIOs by flushing the MMIOs
that must be strictly ordered (such as the send mailbox). Determining
when to enable the flush is currently a manual process of adding known
chipsets to a list.
The new code replaces the BUG_ON() in the tx completion path with the
call to tg3_tx_recover(). It will set the TG3_FLAG_MBOX_WRITE_REORDER
flag and reset the chip later in the workqueue to recover and start
flushing MMIOs to the mailbox.
A message to report the problem will be printed. We will then decide
whether or not to add the host bridge to the list of chipsets that do
re-ordering.
We may add some additional code later to print the host bridge's ID so
that the user can report it more easily.
The assumption that re-ordering can only happen on x86 systems is also
removed.
