Subject: [PATCH v2] ACPI, APEI, EINJ, limit the range of einj_param
Date: Sat, 3 Mar 2012 11:56:43 +0800 [thread overview]
Message-ID: <1330747003-11891-1-git-send-email-gong.chen@linux.intel.com> (raw)
In-Reply-To: <4F506E8A.8010901@linux.intel.com>
On the platforms with ACPI4.x support, parameter extension
is not always doable, which means only parameter extension
is enabled, einj_param can take effect.
v2->v1: stopping early in einj_get_parameter_address for einj_param
