Make ZBus tracing generic - moving it to a common direcotry under
arch/mips/sibyte, add bcm1480 support and fix some wait related
bugs (thanks to Ralf for assistance on that).

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.

Gcc major version number is in __GNUC__. As side effect fix checking
with sparse if sparse was built with gcc 4.1 and mips cross-compiler
is 3.4.
Sparse will inherit version 4.1, __GNUC__ won't be filtered from
"-dM -E -xc" output, sparse will pick only new major, effectively becoming
gcc version 3.1 which is unsupported.

This is a patch to load 64-bit modules to CKSEG0 so that can be
compiled with -msym32 option. This makes each module ~10% smaller.
* introduce MODULE_START and MODULE_END
* custom module_alloc()
* PGD for modules
* change XTLB refill handler synthesizer
* enable -msym32 for modules again
(revert ca78b1a5c6a6e70e052d3ea253828e49b5d07c8a)
New XTLB refill handler looks like this:

On 64-bit kernel, modules are loaded into XKSEG for now. While XKSEG
address is not a sign-extended 32-bit address, we can not use -msym32
option.

Certain gcc versions upto gcc 4.1.1 (probably 4.2-subversion as of
2006-10-10 don't properly change the the predefined symbols if -EB / -EL
are used, so we kludge that here. A bug has been filed at
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29413.

This commit breaks sparse for 64bit kernel. The -m64 option is
required. Also, some macro values (such as _MIPS_TUNE, etc.) contain
double-quote characters so it would be better quoting arguments by
single-quote characters.

This fixes kernel builds with gcc 3.2 (not 64-bit, that is looking like
it is beyond recovery) and 3.3. With these bugs fixed we now also can
get undo 3b4c4996a0c24da9e6f8be764e3950b756b18cc0 and similar bits for
SMTC that were added in 79cc8007b93838a670b164b8a55ab3e735a12a8b.

Adding -mmad is not usable since over half a decade in gcc and when
fixed the proper -march option values should enable the use of the
mad, madu and mul instructions of the R5500, RM5200, RM7000 and RM9000
families.

This was a stop gap meassure for gcc 3.3 and newer sometimes not inlining
inline functions in the 2.4 days. Starting we pass the always_inline
attribute, so -finline-limit is no longer necessary and it's been shown
to problematic on Sparc.
