x86: Update copyright statement 
Commit d0ccf2f96f contains the makecontext
fix from Adélie commit aaeb73ea701388e55b7640e32509a5f6a57f6350[1], as
seen at AdelieLinux/libucontext@aaeb73ea – but it didn't include the
addition of my author line.

The full commit text, for future documentation/reference, was:

```
x86: Write link pointer at correct stack offset

It must come *after* the parameters, not *before*.
```

Fixes: d0ccf2f96f ("x86: modernize")

Bobby Bingham 2610c7faa7 ppc32/64: rewrite get/set/swapcontext in assembly 
getcontext cannot be correctly implemented in C.

If this calls another function, as it does to call syscall, it needs to
first spill its return address to the stack.  If, after getcontext returns,
its caller then calls other functions, this saved return address can be
clobbered.  When the context saved by getcontext is later restored, the
(now clobbered) return address will be reloaded from the stack, and the
second return from getcontext will return to the wrong location.

Because the powerpc swapcontext syscall allows either the old context or
new context pointers to be null, it is usable for implementing all of
get/set/swapcontext.

We therefore rewrite swapcontext in assembly, and get/setcontext as simple
assembly function wrappers around swapcontext.

The one piece we keep in C is the code to check the return value of the
system call and to set errno.  This code was actually unnecessary before --
libc does this within syscall.  However, now that the system call is made
directly in assembly, bypassing libc, it is truly necessary.  Because errno
is thread-local and the details of how to set it can vary by libc, this
code remains written in C.

Bobby Bingham 40d07758a5 ppc32/64: correct signature of function parameter to makecontext 
Because makecontext can pass a set of integer arguments to the provided
function, it is incorrect to require that this function accept no
parameters.

Bobby Bingham a00a05ce29 ppc64: fix incorrect position of parameters within stack frame 
On PPC64, there are 4 register-sized stack slots below the parameter save
area, which is different from the 2 stack slots on PPC32.
