[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

[RFC PATCH v6 00/92] VM introspection
The KVM introspection subsystem provides a facility for applications running
on the host or in a separate VM, to control the execution of other VM-s
(pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.),
alter the page access bits in the shadow page tables (only for the hardware
backed ones, eg. Intel's EPT) and receive notifications when events of
