Log Message:
Pull up following revision(s) (requested by pgoyette in ticket #770):
sys/compat/netbsd32/netbsd32_mod.c: revision 1.19
If a syscall requires a module to be autoloaded, the initial invocation
of that syscall will return ERESTART. For amd64's netbsd32_syscall()
that means we need to back up the PC saved in the trap frame so we can
re-issue the syscall instruction. For "normal" syscall traps, we saved
the instruction length in the trap frame, but this was missing for the
oosyscall/lcall path. Since the PC was not backed up, the kernel-only
value ERESTART was returned to userland, causing all sort of grief for
old compat_netbsd32 executables!
