Greetings,
after Carsten pitched CMM2 on the kvm mini summit here is a repost
of version 5 of the guest page hinting patches. The code is still
the same but has been adapted to the latest git level.

[patch 0/6] [rfc] guest page hinting version 5
After way to many months here is the fifth version of the guest page
hinting patches. Compared to version four a few improvements have been
added:
- Avoid page_host_discards() calls outside of page-states.h
- The discard list is now implemented via the page_free_discarded
hook and architecture specific code.
- PG_state_change page flag has been replaced with architecture
