d9e651bc06 netxen: cut-through rx changes
NX3031 supports cut-through operation where ingress packets are
directly dma'ed into host buffers to reduce latency.

This requires larger dma buffers (2kb) and different alignemnt.

The buffer posting logic is changed a bit. The free rx buffers
are maintained in linked list, since the received reference
handles can be out of order. However rx descriptors are still
posted sequentially, indexed by producer.

768aec0b5b serial: 8250: fix shared interrupts issues with SMP and RT kernels
With SMP kernels _irqsave spinlock disables only local interrupts, while
the shared serial interrupt could be assigned to the CPU that is not
currently starting up the serial port.

This might cause issues because serial8250_startup() routine issues
IRQ-triggering operations before registering the port in the IRQ chain
(though, this is fine to do and done explicitly because we don't want to
process any interrupts on the port startup).

With RT kernels and preemptable hardirqs, _irqsave spinlock does not
disable local hardirqs, and the bug could be reproduced much easily:

$ cat /dev/ttyS0 &
$ cat /dev/ttyS1

Disabling IRQ #42

After this, all serial ports on the given IRQ are non-functional.

To fix the issue we should explicitly disable shared IRQ before
issuing any IRQ-triggering operations.

I also changed spin_lock_irqsave to the ordinary spin_lock, since it
seems to be safe: chain does not contain new port (yet), thus nobody
will interfere us from the ISRs.

88e882497d Fix the epca driver to permit epca_setup() to be invoked from the kernel cmdline
Fix the epca driver to call epca_setup() if digiepca=xxx is included on the
command line and the epca driver is built in.

epca_setup() used to be called from init/main.c in 2.2 kernels, but somewhere
along the way that call was removed but not replaced.

4a56122297 Fix the (i)Stallion driver's putchar() and break_ctl() ops
Fix the Stallion driver's putchar() and break_ctl() ops and iStallion's
putchar() to return values.

Is it actually possible for putchar() or break_ctl() to be called with tty ==
NULL or can the check be discarded?

Should stl_write() be returning 0 if tty->driver_data is NULL or tx.buf is
NULL?  Is this even possible?

I've made Stallion's functions return -EINVAL as stli_breakctl() if the checks
fail.
