I found this in latest 2.6.24-rc2:
--
Cscope tag: dump_thread
# line filename / context / line
1 324 arch/alpha/kernel/process.c <<dump_thread>>
dump_thread(struct pt_regs * pt, struct user * dump)

void dump_thread(struct pt_regs * regs, struct user * dump)

void dump_thread(struct pt_regs *regs, struct user *dump)
