Alexey Dobriyan 48c35b2d24 [MIPS] There is no __GNUC_MAJOR__
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.

Atsushi Nemoto 656be92f9a [MIPS] Load modules to CKSEG0 if CONFIG_BUILD_ELF64=n
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:

Atsushi Nemoto 236d333c3c [MIPS] Do not use -msym32 option for modules.
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

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.
