Supporting non-x86 archs needs more than just some glue code. First the target arch would need support for changing syscall numbers with ptrace(), or even better PTRACE_SYSEMU support. UML also depends on mcontext of SIGSEGV to get the faulting address. On ARM for example VIVT caches could be a problem too. Al has all the glory details...
