d582799fe5 um/arch_prctl: Fix fallout from x86 arch_prctl() rework 
The recent arch_prctl rework added a bracket instead of a comma. Fix it.

Fixes: 17a6e1b8e8 ("x86/arch_prctl/64: Rename do_arch_prctl() to do_arch_prctl_64()")

17a6e1b8e8 x86/arch_prctl/64: Rename do_arch_prctl() to do_arch_prctl_64() 
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.

dd93938a92 x86/arch_prctl: Rename 'code' argument to 'option' 
The x86 specific arch_prctl() arbitrarily changed prctl's 'option' to
'code'. Before adding new options, rename it.

d2ce4e92fa um: kill thread->forking 
we only use that to tell copy_thread() done by syscall from that
done by kernel_thread().  However, it's easier to do simply by
checking PF_KTHREAD in thread flags.

Merge sys_clone() guts for 32bit and 64bit, while we are at it...
