I've revised the patch from the review comments (thank you) and
is attached.
Regtested on x86_64 and powerpcle64.
OK for trunk?
What is the goal? Do you want this to return the correct value or only
the value for the supported 64 bit PPC64LE system?
Thanks, David
The goal is to support both 32-bit and 64-bit. There was some
confusion on my part, my apologies.
Attached is the corrected patch.
Thanks!
