+
+ * linux-low.c (wait_for_sigstop): Always switch to no thread
+ selected if the previously current thread dies.
+ * lynx-low.c (lynx_request_interrupt): Use the first thread's
+ process instead of the current thread's.
+ * remote-utils.c (input_interrupt): Don't check if there's no
+ current thread.
+ * server.c (gdb_read_memory, gdb_write_memory): If setting the
+ current thread to the general thread fails, error out.
+ (handle_qxfer_auxv, handle_qxfer_libraries)
+ (handle_qxfer_libraries_svr4, handle_qxfer_siginfo)
+ (handle_qxfer_spu, handle_qxfer_statictrace, handle_qxfer_fdpic)
+ (handle_query): Check if there's a thread selected instead of
+ checking whether there's any thread in the thread list.
+ (handle_qxfer_threads, handle_qxfer_btrace)
+ (handle_qxfer_btrace_conf): Don't error out early if there's no
+ thread in the thread list.
+ (handle_v_cont, myresume): Don't set the current thread to the
+ continue thread.
+ (process_serial_event) <Hg handling>: Also set thread_id if the
+ previous general thread is still alive.
+ (process_serial_event) <g/G handling>: If setting the current
+ thread to the general thread fails, error out.
+ * spu-low.c (spu_resume, spu_request_interrupt): Use the first
+ thread's lwp instead of the current thread's.
+ * target.c (set_desired_thread): If the desired thread was not
+ found, leave the current thread pointing to NULL. Return an int
+ (boolean) indicating success.
+ * target.h (set_desired_thread): Change return type to int.

* configure.srv (xtensa*-*-linux*): Add srv_linux_thread_db=yes.
