Hi,
I have reviewed the code and in my opinion the line
last_tx_bd = fep->tx_bd_base + (fpi->tx_ring *
sizeof(cbd_t));
should be replaced with
last_tx_bd = fep->tx_bd_base + ((fpi->tx_ring-1) *
sizeof(cbd_t));

Although call_rtas_display_status() does actually want to use the
regular RTAS locking, it doesn't want the extra logic that is in
rtas_call(), so currently it open codes the logic.
Instead we can use rtas_call_unlocked(), after taking the RTAS lock.

There are no longer any users of enter_rtas() outside of rtas.c, so make
it "private", by moving the declaration inside rtas.c. Hopefully this
will encourage people to use one of the wrappers which takes the sharp
edges off the RTAS calling sequence.

I was looking for an error on MPC8270 processor 100 Mbps Ethernet FCC port.
The port may become locked if it is set to AUTO, while the peer is forced to
100 Mbs full duplex (non AUTO).
I was looking for an error in the area of collision handling of the driver.
It looks like I found the problem.

TRACE_EVENT_FN can't be used in some circumstances
like invoking trace functions from offlined CPU due
to RCU usage.
This patch adds the TRACE_EVENT_FN_COND macro
to make such trace points conditional.

The ml command in xmon currently only works for 32-bit values and so fails

Currently if you are in xmon without an oops etc. to view the kernel version
you have to type "d $linux_banner" - not necessarily obvious. As this is useful

The STD_EXCEPTION_PSERIES macro takes both a vector number, and a
location (memory address). However both are always identical, so combine
them to save repeating ourselves.
This does mean an exception handler must always exist at the location in
memory that matches its vector number. But that's OK
On BMC machines, console output is controlled by the OPAL firmware and is
only flushed when its pollers are called. When the kernel is in a panic
state, it no longer calls these pollers and thus console output does not
completely flush, causing some output from the panic to be lost.
