MIPS: Two-level pagetables for 64-bit kernels with 64KB pages.
For 64-bit kernels with 64KB pages and two level page tables, there are
42 bits worth of virtual address space This is larger than the 40 bits of
virtual address space obtained with the default 4KB Page size and three
levels, so there are no draw backs for using two level tables with this
configuration.

MIPS: Use PAGE_SIZE in assembly instead of _PAGE_SIZE.
Now that PAGE_SIZE is available to assembly directly, there is no need
to separately expose it as _PAGE_SIZE through asm-offsets.
In addition, remove _PAGE_SHIFT from asm-offsets, since it was never
needed, and is not used anywhere.

MIPS: Add hibernation support
[Ralf: SMP support requires CPU hotplugging which MIPS currently doesn't
support. As implemented in this patch cache and tlb flushing will also be
invoked with interrupts disabled so smp_call_function() will blow up in
charming ways. So limit to !SMP.]

pageflags: standardize comment inclusion in asm-offsets.h and fix MIPS
Add the ability to pass comments into asm-offsets.h by generating asm
output like
-># comment line
Mips needs this feature to preserve the comments that are in
asm-mips/asm-offsets.h right now.
Then remove the special handling for mips from Kbuild and convert mips to use
the new string to include the comments.

rename thread_info to stack
This finally renames the thread_info field in task structure to stack, so that
the assumptions about this field are gone and archs have more freedom about
placing the thread_info structure.
Nonbroken archs which have a proper thread pointer can do the access to both
current thread and task structure via a single pointer.
It'll allow for a few more cleanups of the fork code, from which e.g. ia64
could benefit.

[MIPS] Add basic SMARTMIPS ASE support
This patch adds trivial support for SMARTMIPS extension. This extension
is currently implemented by 4KS[CD] CPUs.
Basically it saves/restores ACX register, which is part of the SMARTMIPS
ASE, when needed. This patch does *not* add any support for Smartmips MMU
features.
Futhermore this patch does not add explicit support for 4KS[CD] CPUs since
they are respectively mips32 and mips32r2 compliant. So with the current
processor configuration, a platform that has such CPUs needs to select
both configs:
CPU_HAS_SMARTMIPS
SYS_HAS_CPU_MIPS32_R[12]
This is due to the processor configuration which is mixing up all the
architecture variants and the processor types.
The drawback of this, is that we currently pass '-march=mips32' option to
gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This
can lead to a kernel image a little bit bigger than required.

[MIPS] signal32: no need to save c0_status register in setup_sigcontext32()
All the information in the MIPS c0_status register is priviledged.
Nothing that would constitute part of the thread context.
The one flag one could possibly argument about might be c0_status.fr
but none of the ABIs or tools or application software can make use
of it.
So for consistency with restore_sigcontext32(), which does not
restore c0_status register, this patch remove the saving part.
