With the help of script/checkpatch.pl, i have cleaned up the coding
style.

1. remove un-needed header files and tune some comments.
2. remove some un-needed { }

add a new header file loongson.h:

3. move some common header files to loongson.h
4. move some common extern declartions to loongson.h

and this new header file is needed for future loongson2f support.

This patch split the old initilization and setup implementation to
several file, one file one logic function.

the other main changes include:

	1. as the script/checkpatch.pl suggests, use strict_strtol instead
	of simple_strtol in arch/mips/lemote/lm2e/cmdline.c

	2. use the existed macros in asm/mips-boards/bonito64.h as the
	arguments of set_io_port_base() and remove the un-needed ones in
	asm/mach-lemote/pci.h

Removes the existing implementation of early_printk for fulong.  The old
implementation was based on the outdated board-specific dbg_io.c.

Since commit 8d60a903 dbg_io.c is not longer
needed; it will be removed by the next patch, and a new implementation of
early_printk will be added later.

The current code only checks CCA of 0 when deciding if a dummy read is
needed.  Since the kernel can (and does) use other CCAs we need to
mask out the CCA bits from the address.  Since the address constant
now fits in 16 bits, there is an added benefit that smaller code is
generated.

If we reach the test just below the loop with a `timeout' value of 0,
this does not mean that the timeout caused the loop to end, but rather
the `smi_rd.s.pending', in the last iteration. If timeout caused the
loop to end, then `timeout' is -1, not 0.

Since this can occur only in the last iteration, it is not very likely
to be a problem. By changing the post- to prefix decrement we ensure
that a timeout of 0 does mean it timed out.

The mcount support that was finally added to the Blackfin gcc port isn't
exactly the same as what ftrace was developed against.  Now that the final

While updating this, fix the swapped arguments to the tracer (signature is
(ip, parent_ip) while we were passing (parent_ip, ip)).

The elf_fpregset_t type relied on an empty struct in the asm/user.h, but
the transition to asm-generic/user.h dropped that empty struct.  Rather
than restore this useless struct, define the only user (elf_fpregset_t)
as an empty struct itself.  This fixes building when ELF dump support is
enabled.
