[PATCH v2 2/8] mm: convert PG_balloon to PG_offline

PG_balloon was introduced to implement page migration/compaction for pages inflated in virtio-balloon. Nowadays, it is only a marker that a page is part of virtio-balloon and therefore logically offline. We also want to make use of this flag in other balloon drivers - for inflated pages or when on

[PATCH v2 1/8] mm: balloon: update comment about isolation/migration/compaction

Commit b1123ea6d3b3 ("mm: balloon: use general non-lru movable page feature") reworked balloon handling to make use of the general non-lru movable page feature. The big comment block in balloon_compaction.h contains quite some outdated information. Let's fix this. Cc: Andrew Morton Cc: Matthew Wi

[PATCH v2 3/8] kexec: export PG_offline to VMCOREINFO

Right now, pages inflated as part of a balloon driver will be dumped by dump tools like makedumpfile. While XEN is able to check in the crash kernel whether a certain pfn is actuall backed by memory in the hypervisor (see xen_oldmem_pfn_is_ram) and optimize this case, dumps of other balloon inflate

[PATCH v2 7/8] PM / Hibernate: use pfn_to_online_page()

[PATCH v2 8/8] PM / Hibernate: exclude all PageOffline() pages

The content of pages that are marked PG_offline is not of interest (e.g. inflated by a balloon driver), let's skip these pages. In saveable_highmem_page(), move the PageReserved() check to a new check along with the PageOffline() check to separate it from the swsusp checks. Cc: "Rafael J. Wysocki

[PATCH v2] makedumpfile: exclude pages that are logically offline

Linux marks pages that are logically offline via a page flag (map count). Such pages e.g. include pages infated as part of a balloon driver or pages that were not actually onlined when onlining the whole section. While the hypervisor usually allows to read such inflated memory, we basically read a
