Thanks for this change. It seems that it was from linux/ptrace.h to sys/ptrace.h
in https://bugs.openjdk.java.net/browse/JDK-8046408 due to a glibc bug which has
long since been fixed. I had reports that this had broken linux-sparc a while
back, but no hardware to verify it myself. It's good to see this fixed and
I hope it can go back to 8 as well.

Thanks,
