Subject: [PATCH v5 07/27] arm64: xen: Use existing helper to check interrupt status
Date:   Tue, 28 Aug 2018 16:51:17 +0100
Message-Id: <1535471497-38854-8-git-send-email-julien.thierry@arm.com>
In-Reply-To: <1535471497-38854-1-git-send-email-julien.thierry@arm.com>
References: <1535471497-38854-1-git-send-email-julien.thierry@arm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The status of interrupts might depend on more than just pstate. Use
interrupts_disabled() instead of raw_irqs_disabled_flags() to take the full
context into account.
