        src/sys/arch/sparc64/sparc64: vm_machdep.c
 
 Log Message:
 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.
