SubjectRe: + ehea-fix-dlpar-memory-handling.patch added to -mm tree
Date
Hello,

please consider the ehea-fix-dlpar-memory-handling.patch as critical bug fix,
as it fixes a potential firmware error causing the driver to get inoperable
when system memory is sparse. Therefore please include this fix into 2.6.27.

Regards

Hannes
