I'd suggest sending this direct to Linus as I've been doing with the other fixes for Spectre BHB. Trying to fit it now into a pull request is just going to be very messy.

-- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
