Subject: [PATCH 03/15] arm64: Add ARM64_HYP_OFFSET_LOW capability
Date: Tue, 7 Jun 2016 11:58:23 +0100 [thread overview]
Message-ID: <1465297115-13091-4-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1465297115-13091-1-git-send-email-marc.zyngier@arm.com>
As we need to indicate to the rest of the kernel which region of
the HYP VA space is safe to use, add a capability that will
indicate that KVM should use the [VA_BITS-2:0] range.
