[PATCH] m32r: fix and update for gcc-4.0
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.
