Subject: [PATCH 01/07] i386: srat non acpi
Date: Fri, 30 Sep 2005 16:33:21 +0900 (JST) [thread overview]
Message-ID: <20050930073237.10631.27035.sendpatchset@cherry.local> (raw)
In-Reply-To: <20050930073232.10631.63786.sendpatchset@cherry.local>
This patch adds code to check the return value of acpi_find_root_pointer().
Without this patch systems without ACPI support such as QEMU crashes when
booting a NUMA kernel configured with CONFIG_ACPI_SRAT=y.
