From 169cd0f8238f2598b85d2db2e15828e8f8da18e5 Mon Sep 17 00:00:00 2001 From: Quentin Perret Date: Thu, 10 Nov 2022 19:02:57 +0000 Subject: KVM: arm64: Don't unnecessarily map host kernel sections at EL2 We no longer need to map the host's '.rodata' and '.bss' sections in the stage-1 page-table of the pKVM hypervisor at EL2, so remove those mappings and avoid creating any future dependencies at EL2 on host-controlled data structures.
