Rename the variable "sum" in the __range_ok macros to avoid name collisions
causing lots of "symbol shadows an earlier one" warnings by sparse.

Update {get,put}_user macros for m32r kernel.
- Modify get_user to use __get_user_asm macro, instead of __get_user_x macro.
- Remove arch/m32r/lib/{get,put}user.S.
- Some cosmetic updates.
I would like to thank NIIBE Yutaka for his reporting about the m32r kernel's
security problem in {get,put}_user macros.
There were no address checking for user space access in {get,put}_user macros.

Fix and update for gcc-4.0.
- arch/m32r/kernel/signal.c:
Change type of the 8th parameter of sys_rt_sigsuspend() from
'struct pt_regs' to 'struct pt_regs *'.
This functions make use of the 'regs' parameter to return status value,
but gcc-4.0 optimizes and removes it as a dead code.
Functions, sys_sigaltstack() and sys_rt_sigreturn(), have also modified.
- arch/m32r/lib/usercopy.c, include/asm-m32r/uaccess.h:
Add early-clobber constraints('&') to output values of asm statements;
these constraints seems to be required for gcc-4.0 register assignment.

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!
