From dac288f7b38a7439502b77dabcdf8a9a5c4ae721 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Tue, 14 May 2013 12:11:37 +0100 Subject: [PATCH] ARM: KVM: use phys_addr_t instead of unsigned long long for HYP PGDs HYP PGDs are passed around as phys_addr_t, except just before calling into the hypervisor init code, where they are cast to a rather weird unsigned long long. Just keep them around as phys_addr_t, which is what makes the most sense.
