The new FW improves the packets per second rate. It required a lot of change in
the FW which implies many changes in the driver to support it. It is now also
possible for the driver to use a separate MSI-X vector for Rx and Tx - this also
add some to the complicity of this change.
All things said - after this patch, practically all performance matrixes show
improvement.
Though Vladislav Zolotarov is not signed on this patch, he did most of the job
and deserves credit for that.

Improve myri10ge parity error detection and recovery:
1) Don't restore PCI config space to a rebooted NIC until AFTER the
host is quiescent.
2) Let myri10ge_close() know the NIC is dead, so it won't waste time
waiting for a dead nic to respond to MXGEFW_CMD_ETHERNET_DOWN
3) When the NIC is quiet (link down, or otherwise idle link) use
a pci config space read to detect a rebooted NIC. Otherwise
we might never notice that a NIC rebooted

In general in this file, it is the status field, not the state field, that
contains values like OPEN and CLOSED. Indeed, in the first error case, it
is the field status that is initialized. I have thus assumed that all of
the error handling code should be the same, and moved it to the end of the
function to emphasize its commonality.

In all rx'd SKB cases, atalk_rcv() either eventually jumps to or falls through
to the label out:, which returns numeric 0. Numeric 0 corresponds to
NET_RX_SUCCESS, which is incorrect in failed SKB cases.
This patch makes atalk_rcv() provide the correct returns by:
o explicitly returning NET_RX_SUCCESS in the two success cases
o having the out: label return NET_RX_DROP, instead of numeric 0
o making the failed SKB labels and processing more consistent with other
_rcv() routines in the kernel, simplifying validation and removing a
backwards goto

Instead of a large (physically) linear buffer, we generate a set of
paged sk_buff, so no extra memory copy is involved. This removes
high-order allocations and saves quite a bit of memory. Phonet MTU is
65541 bytes, so the two buffers were padded to 128 kilo-bytes each.
Now, we create 17 page buffers, almost a 75% memory use reduction.

Convert the processor platform device setup
functions from __initcall() and sometimes
device_initcall() to arch_initcall().
This makes sure that the platform devices are
registered a bit earlier so the devices are
available when drivers register using initcall
levels earlier than device_initcall().
A good example is platform devices needed by
i2c-sh_mobile.c which registers a bit earlier
using subsys_initcall().

Normally we only allow the upper limit for a reshape to be decreased
when the array not performing a sync/recovery/reshape, otherwise there
could be races. But if an array is part-way through a reshape when it
is assembled the reshape is started immediately leaving no window
to set an upper bound.
If the array is started read-only, the reshape will be suspended until
the array becomes writable, so that provides a window during which it
is perfectly safe to reduce the upper limit of a reshape.
So: allow the upper limit (sync_max) to be reduced even if the reshape
thread is running, as long as the array is still read-only.
