powerpc: Remove dead code in sycall entry
In:
commit 742415d6b66bf09e3e73280178ef7ec85c90b7ee
Author: Michael Neuling <mikey@neuling.org>
powerpc: Turn syscall handler into macros
We converted the syscall entry code onto macros, but in doing this we
introduced some cruft that's never run and should never have been added.
This removes that code.
