Subject: [PATCH v3 13/26] KVM: arm64: Always populate the trap configuration xarray
Date: Mon, 5 Feb 2024 10:34:18 +0000 [thread overview]
Message-ID: <20240205103431.1104133-14-maz@kernel.org> (raw)
In-Reply-To: <20240205103431.1104133-1-maz@kernel.org>
As we are going to rely more and more on the global xarray that
contains the trap configuration, always populate it, even in the
non-NV case.
