[PATCH 15/18] KVM: arm/arm64: Demote HYP VA range display to being a debug feature

[Marc Zyngier]

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.
