        sys/arch/sparc64/sparc64/vm_machdep.c: revision 1.88
Deja Vu: when preparing the initial trap frame for a new forked lwp,
explicitly clear condition code. Otherwise we might catch a signal
(handlers are inherited from the parent) before we ever return to
userland. The current trapframe is converted into a ucontext and after
the signal handler returns, the lwp stays in userland and directly
uses the ucontext to return to the fork call.
Fixes PR 41302.
