Module Name:    src
Committed By:   riastradh

Modified Files:
        src/sys/kern: sys_process_lwpstatus.c

Log Message:
ptrace/procfs: Take lwp lock around process_read/write_(fp)regs(32).

And verify that the lwp is in LSSTOP state before trying to read.
Otherwise, we might catch an lwp while it's still running on the CPU,
with all FPU state active, making the result unstable and tripping
assertions on some architectures.

PR port-amd64/60556: panic in process_read_fpregs_xmm
