>> Hi, This is also needed for riscv-port-jdk11u repo where we have full-reatured linux-riscv port for the same reason as jdk17u backport. The backport is not clean because the sparc architecture related code still exists. Risk is low as this is a small change prefering using `PTRACE_GETREGSET` instead of `PTRACE_GETREGS`. Tested on linux-aarch64 and linux-x86_64 platforms.
