In order to introduce new arch_prctls that are not 64 bit only, rename the
existing 64 bit implementation to do_arch_prctl_64(). Also rename the
second argument of that function from 'addr' to 'arg2', because it will no
longer always be an address.

The x86 specific arch_prctl() arbitrarily changed prctl's 'option' to
'code'. Before adding new options, rename it.

On recent toolchains we hit:
In file included from arch/x86/um/os-Linux/prctl.c:7:0:
/usr/include/linux/ptrace.h:58:8: error: redefinition of ‘struct
ptrace_peeksiginfo_args’ struct ptrace_peeksiginfo_args {

In file included from arch/x86/um/os-Linux/prctl.c:6:0:

struct ptrace_peeksiginfo_args

make[1]: *** [arch/x86/um/os-Linux] Error 2
make: *** [arch/x86/um] Error 2
The solution is not to include linux/ptrace.h and obtain
the arch specific ptrace command from asm/ptrace.h.
