From 6e3bfbb22c51bd1f121ca5c4bce6b51dc6cdceae Mon Sep 17 00:00:00 2001 From: Andrew Scull Date: Tue, 15 Sep 2020 11:46:30 +0100 Subject: KVM: arm64: nVHE: Use separate vector for the host The host is treated differently from the guests when an exception is taken so introduce a separate vector that is specialized for the host. This also allows the nVHE specific code to move out of hyp-entry.S and into nvhe/host.S. The host is only expected to make HVC calls and anything else is considered invalid and results in a panic. Hyp initialization is now passed the vector that is used for the host and it is swapped for the guest vector during the context switch.
