We have calculated VMLINUZ_LOAD_ADDRESS in shell, which is indecipherable. This
patch rewrites it in C.

The compressed vmlinux.bin is only a temp file so it's ok to use the same
suffix .z for them (.gz,.lzo,.lzma...) to remove several lines and simpify
the maintenance (no need to add the "suffix_$(xxx) := suffix" line).

Nvram_getenv should behave like cfe_getenv. cfe_getenv returns 0 on
success and -9 if the value was not found. If the input was wrong -8
will be returned by cfe_getenv. Change nvram_getenv to do the same.

We reserve the 3.75GB - 4GB region of PCIe address space for device to
device transfers, making the corresponding physical memory under
direct mapping unavailable for DMA.
To allow for PCIe DMA to all physical memory we map this chunk of
physical memory with BAR1. Because of the resulting discontinuity in
the mapping function, we remove a page of memory at each end of the
range so multi-page DMA buffers can never be allocated that span the
range.

The sixth argument of notify_die() is a signal number, the fifth is a
trap number.
Instead of passing a signal number in a randomly selected argument,
pass it in the sixth. Extract the exception code from regs and pass
that as the trap number.
Get rid of redundant cast, and remove some gratuitous spaces.
Nobody actually does anything with the signal number or trap number,
but we might as well populate them with sensible values.

This patch is based on previous work by Sony and Himanshu Chauhan.
I have done some cleanup and implemented JProbes and KRETPROBES. The
KRETPROBES part is pretty much copied verbatim from powerpc. A possible
future enhance might be to factor out the common code.

On FuLoong-2F IP6 is shared by the performance counter overflow interrupt
and the Bonito northbridge interrupt. To reduce overhead only call
do_IRQ() when oprofile is enabled to reduce overhead.
This patch adds an inline function do_perfcnt_IRQ() to hide the #if's ,
which can be shared by the other Loongson machines, i.e. gdium.

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.
