do_IRQ() when oprofile is enabled to reduce overhead.

This patch adds an inline function do_perfcnt_IRQ() to hide the #if's ,

The OCTEON is a MIPS64 based SOC family with an on chip watchdog unit.

The driver is split into two source files one for the C code and one
for assembly.  Assembly is needed to handle the NMI and then print the
machine state before the reboot is triggered.

A 'select EXPORT_UASM' in Kconfig will cause the uasm to be exported
for use in modules.  When it is exported, all the uasm data and code
cease to be __init and __initdata.

Also daddiu_bug cannot be __cpuinitdata if uasm is exported.  The
cleanest thing is to just make it normal data.

The JZ4740 UART interface is almost 16550 compatible.
The UART module needs to be enabled by setting a bit in the FCR register
and it has support for receive timeout interrupts.  Instead of adding yet
another machine specific quirk to the 8250 serial driver we provide a
serial_out implementation which sets the required additional flags.
