Subject: [PATCH v2 85/94] KVM: arm64: Disintegrate SPSR array
Date: Tue, 11 Feb 2020 17:49:29 +0000
Message-ID: <20200211174938.27809-86-maz@kernel.org> (raw)
In-Reply-To: <20200211174938.27809-1-maz@kernel.org>
As we're about to move SPSR_EL1 into the VNCR page, we need to
disassociate it from the rest of the 32bit cruft. Let's break
the array into individual fields.
