69a6c312e5 [MIPS] Move some kernel globals from asm file to C file. 
This get rid of some undesirable hole in BSS section due to random
order of placement.

c25c79d80e [MIPS] Qemu now has an ELF loader. 
So nuke kludge for flat binaries.

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:

1da177e4c3 Linux-2.6.12-rc2 
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
