Paolo
Paolo & Radim, Immediately after I sent my previous pull request, I saw that Suraj had posted a patch that advertises a new mitigation for one of the spectre vulnerabilities to userspace. The code for the host to know about and use this new mitigation went into 4.19. Since the patch is low-risk and security-related, I would like to get it into 5.1. With this patch and a related QEMU patch, guests will be able to use this new mitigation on machines that support it. So, please do a pull from my kvm-ppc-next-5.1-3 tag to get this commit. (If you haven't already pulled the 5.1-2 tag then you will get the compile fix as well, of course.) Thanks, Paul.
