/* $NetBSD: aoutm68k_exec.c,v 1.12 2002/11/10 20:59:04 jdolecek Exp $ */
Initial cut of COMPAT_AOUT_M68K. This gets most existing m68k a.out binaries working with m68k ELF kernels. There are still some remaining ABI issues to track down; most notably, some ioctl(2) calls are affected by the change.

- Introduce a e_fault field in struct proc to provide emulation specific memory fault handler. IRIX uses irix_vm_fault, and all other emulation use NULL, which means to use uvm_fault. - While we are there, explicitely set to NULL the uninitialized fields in struct emul: e_fault and e_sysctl on most ports - e_fault is used by the trap handler, for now only on mips. In order to avoid intrusive modifications in UVM, the function pointed by e_fault does not has exactly the same protoype as uvm_fault: int uvm_fault __P((struct vm_map *, vaddr_t, vm_fault_t, vm_prot_t)); int e_fault __P((struct proc *, vaddr_t, vm_fault_t, vm_prot_t)); - In IRIX share groups, all the VM space is shared, except one page. This bounds us to have different VM spaces and synchronize modifications to the VM space accross share group members. We need an IRIX specific hook to the page fault handler in order to propagate VM space modifications caused by page faults.

m68k syscall rototill: - Switch all m68k-based ports over to __HAVE_SYSCALL_INTERN. - Add systrace glue. - Define struct mdproc in <m68k/proc.h> instead of <machine/proc.h>. (They were all defined exactly the same anyway, other than a couple of the MDP_* flags.)

#ifndef __HAVE_MINIMAL_EMUL
Introduce 2 new flags in types.h: * __HAVE_SYSCALL_INTERN. If this is defined, e_syscall is replaced by e_syscall_intern, which is called at key places in the kernel. This can be used to set a MD syscall handler pointer. This obsoletes and replaces the *_HAS_SEPARATED_SYSCALL flags. * __HAVE_MINIMAL_EMUL. If this is defined, certain (deprecated) elements in struct emul are omitted.
