Log Message:
vax: explicitly zero AP and FP in the CALLS frame in cpu_lwp_fork()
This prevents a recursive panic when ddb(4) tries to trace the stack
back across cpu_lwp_bootstrap(). The CALLS frame in question is put
in place by cpu_lwp_fork() to make it look as if cpu_lwp_bootstrap()
was called from sret, which is detected by db_dump_stack() but only
if the FP of the frame is also 0.
