The code after the vmalloc_fault: label in do_page_fault() modifies

By combining swapper_pg_dir and module_pg_dir, several if conditions
can be eliminated from the tlb exception handler. The reason they
can be combined is that, the effective virtual address of vmalloc
returned is at the bottom, and of module_alloc returned is at the
top. It also fixes the bug in vmalloc(), which happens when its
return address is not covered by the first pgd.

Eliminate the 'allow_au1k_wait' variable.  MIPS kernel installs the
Alchemy-specific wait code before timer initialization;  if the C0
timer must be used for timekeeping the wait function is set to NULL
which means no wait implementation is available.

As a sideeffect, the 'wait instruction available' output in
/proc/cpuinfo now correctly indicates whether 'wait' is usable.

Run-tested on DB1200.

On some CPUs, it is more efficient to disable and enable interrupts in the
kernel rather than use ll/sc for atomic operations.  But if we were to set
cpu_has_llsc to false, we would break the userspace futex interface (in
asm/futex.h).

We separate the two concepts, with a new predicate kernel_uses_llsc, that
lets us disable the kernel's use of ll/sc while still allowing the futex
code to use it.

Also there were a couple of cases in bitops.h where we were using ll/sc
unconditionally even if cpu_has_llsc were false.

Because only gcc >=4.4 have loongson-specific support, we need to choose
the suitable -march argument for gcc <= 4.3 and gcc >= 4.4, and here, we
use -march=loongson2e for loongson2e.

Thanks goes to Arnaud Patard <apatard@mandriva.com> for suggestion of
using cc-options(Documentation/kbuild/makefiles.txt). and thanks Zhang
Le for introducing the new CPU_LOONGSON2E kernel option.

The difference between some loongson-based machines is very small, so, if
there is no necessary to add new kernel config options to cope with this
difference, it will be better to share the same kernel image file between
them, benefit from this, the linux distribution developers only have a need
to compile the kernel one time.

This machtype kernel command line argument will be used later to share the
same kernel image file between two different machines(menglong & yeeloong)
made by lemote.

Thanks very much to Zhang Le for cleaning up the machtype implementation.

To share common loongson source code between all of the loongson-based
machines. there is a need to split it out of the fuloong-2e/ directory.
at the same time, other according tuning is needed. the machine-specific

To make source code of loongson sharable to the machines(such as gdium)
made by the other companies, we rename arch/mips/lemote to
arch/mips/loongson, asm/mach-lemote to asm/mach-loongson, and rename lm2e
to the name of the machine: fuloong-2e. accordingly, FULONG are renamed to
FULOONG2E to make it distinguishable to the future FULOONG2F.  and also,
some other relative tuning is needed.

This kernel support is needed by the user-space tool:oprofile to profile
linux kernel or applications via loongson2 performance counters. you can
enable this driver via CONFIG_OPROFILE = y or m.

On Loongson2 there are two performance counters, each one can count 16
events respectively. when anyone of the performance counter overflows, an
interrupt will be generated and is routed to the IRQ MIPS_CPU_IRQ_BASE + 6.

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.
