@alicefr - you could add another commit to this PR if you wish to remove those other 's's so all the entries are consistent.

Travis seems unhappy:

INFO: Checking all document URLs
No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.
Check the details on how to adjust your build configuration on: https://docs.travis-ci.com/user/common-build-problems/#Build-times-out-because-no-output-was-received
The build has been terminated

I've restarted it..

@jodh-intel I push with IBM Z as we agreed, or do you want 2 commits?

Hi @alicefr - your change is perfectly fine.

But for consistency, it might be good to drop the 's from the other architectures (as I think they all look better without it now :). That isn't strictly part of your PR, but if you wanted to do that extra bit of tidy-up, you could add a new commit for that (sed -i "s/'s//g" README.md):

Oh - could you just update that 2nd commit? Our tooling is complaining as there is no "body" to that commit:
