Date: Wed, 9 Apr 2014 17:14:31 +0200 Message-Id: <1397056476-9183-4-git-send-email-tomasz.nowicki@linaro.org> X-Mailer: git-send-email 1.7.9.5 In-Reply-To: <1397056476-9183-1-git-send-email-tomasz.nowicki@linaro.org> References: <1397056476-9183-1-git-send-email-tomasz.nowicki@linaro.org> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Currently APEI depends on x86 architecture. It is because of NMI hardware error notification of GHES which is currently supported by x86 only. However, many other APEI features can be still used perfectly by other architectures. This commit adds ACPI_APEI_NMI which will be used in next patches to isolate NMI related code in ghes.c file. Only NMI error notification feature depends on x86 and it is selected by default for x86 arch.
