From: Huang Ying Date: Thu, 8 Dec 2011 03:25:49 +0000 (+0800) Subject: ACPI, Record ACPI NVS regions X-Git-Tag: v3.3-rc1~8^2~2^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b54ac6d2a25084667da781c7ca2cebef52a2bcdd;p=pandora-kernel.git ACPI, Record ACPI NVS regions Some firmware will access memory in ACPI NVS region via APEI. That is, instructions in APEI ERST/EINJ table will read/write ACPI NVS region. The original resource conflict checking in APEI code will check memory/ioport accessed by APEI via general resource management mechanism. But ACPI NVS region is marked as busy already, so that the false resource conflict will prevent APEI ERST/EINJ to work. To fix this, this patch record ACPI NVS regions, so that we can avoid request resources for memory region inside it. Signed-off-by: Huang Ying Signed-off-by: Len Brown --- Reading git-diff-tree failed
