commit 28207615d3f3d639a71df51be9ceed3033bb17c6
Author: John Baldwin <jhb@FreeBSD.org>
Date: Tue Mar 22 12:05:43 2022 -0700
fbsd-nat: Add a low_prepare_to_resume virtual method.
This method can be overridden by architecture-specific targets to
perform additional work before a thread is resumed.
(cherry picked from commit a3627b54280ba306766f2689fb35442f24c4c313)
