[PATCH v4 18/28] gdbstub: Remove watchpoint dead code in gdbserver_fork(

Subject: [PATCH v4 18/28] gdbstub: Remove watchpoint dead code in gdbserver_fork()
Date: Wed, 3 Mar 2021 22:46:58 +0100

gdbserver_fork() is only used in user emulation where we can not
use watchpoints because we need the softmmu slow path to detect
accesses to watchpointed memory. This code doesn't do anything as
declared as stubs in "hw/core/cpu.h". Drop it.
