H A D | kvm_arm.h | diff dbff124e29fa24aff9705b354b5f4648cd96e0bb Wed Jul 09 11:17:04 CDT 2014 Joel Schopp <joel.schopp@amd.com> arm/arm64: KVM: Fix VTTBR_BADDR_MASK and pgd alloc
The current aarch64 calculation for VTTBR_BADDR_MASK masks only 39 bits and not all the bits in the PA range. This is clearly a bug that manifests itself on systems that allocate memory in the higher address space range.
[ Modified from Joel's original patch to be based on PHYS_MASK_SHIFT instead of a hard-coded value and to move the alignment check of the allocation to mmu.c. Also added a comment explaining why we hardcode the IPA range and changed the stage-2 pgd allocation to be based on the 40 bit IPA range instead of the maximum possible 48 bit PA range. - Christoffer ]
