Call ptid_get_pid instead of get_thread_id in aarch64_linux_get_debug_reg_capacity
Commit Message
aarch64_linux_get_debug_reg_capacity is called by
aarch64_linux_child_post_startup_inferior, and argument ptid is created in
inf-ptrace.c:inf_ptrace_create_inferior,
/* On some targets, there must be some explicit actions taken after
the inferior has been started up. */
target_post_startup_inferior (pid_to_ptid (pid));
so in aarch64_linux_get_debug_reg_capacity, we can get pid by ptid_get_pid,
and don't need to use get_thread_id.
Regression tested on aarch64-linux. I'll pushed it in.
