From: Marc Zyngier Date: Sun, 3 Dec 2017 20:04:51 +0000 (+0000) Subject: KVM: arm/arm64: Demote HYP VA range display to being a debug feature X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b4ef04995d33a1ecfec3bdfb7776c1ac36dbe87d;p=openwrt%2Fstaging%2Fblogic.git KVM: arm/arm64: Demote HYP VA range display to being a debug feature Displaying the HYP VA information is slightly counterproductive when using VA randomization. Turn it into a debug feature only, and adjust the last displayed value to reflect the top of RAM instead of ~0.
