apparently the original kernel commit's i386 version of siginfo.h defined this field as unsigned int, but the asm-generic file always had void *. unsigned int is obviously not a suitable type for an address, in a non-arch-specific file, and glibc also has void * here, so I think void * is the right type for it. also fix redundant type specifiers.
