Subject: [RFC PATCH v2 15/38] KVM: arm64: Move exception macros and enums to a common file
Date: Tue, 18 Jul 2017 11:58:41 -0500	[thread overview]
Message-ID: <1500397144-16232-16-git-send-email-jintack.lim@linaro.org> (raw)
In-Reply-To: <1500397144-16232-1-git-send-email-jintack.lim@linaro.org>

These macros and enums can be reused to inject exceptions
for nested virtualization.
