2011-10-16PM / Hibernate: Include storage keys in hibernation image on s390Martin Schwidefsky
For s390 there is one additional byte associated with each page, the storage key. This byte contains the referenced and changed bits and needs to be included into the hibernation image. If the storage keys are not restored to their previous state all original pages would appear to be dirty. This can cause inconsistencies e.g. with read-only filesystems.

2009-09-22[S390] hibernate: make sure pfn_is_nosave handles lowcore pagesHeiko Carstens
pfn_is_nosave doesn't return the correct value for the second lowcore page if lowcore protection is enabled. Make sure it always returns the correct value. While at it simplify the whole thing. NSS special handling is done by the tprot check like it already works for DCSS as well. So remove the extra code for NSS.

2009-09-11[S390] hibernation: merge files and move to kernel/Heiko Carstens
Merge the nearly empty C files and move everything from power/ to kernel/. That way the files are easier to handle. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
