#     powerpc/64: remove support for kernel-mode syscalls
#     
#     There is support for the kernel to execute the 'sc 0' instruction and
#     make a system call to itself. This is a relic that is unused in the
#     tree, therefore untested. It's also highly questionable for modules to
#     be doing this.
