Subject: [PATCH] KVM: selftests: Assert that MPIDR_EL1 is unchanged across vCPU reset
Date: Fri, 21 Jun 2024 22:50:45 +0000 [thread overview]
Message-ID: <20240621225045.2472090-1-oliver.upton@linux.dev> (raw)
commit 606af8293cd8 ("KVM: selftests: arm64: Test vCPU-scoped feature ID
registers") intended to test that MPIDR_EL1 is unchanged across vCPU
reset but failed at actually doing so.
Add the missing assertion.
