Subject: [PATCH 0 of 2] x86/mm: Two hypervisor paging fixes
Date: Mon, 09 Jan 2012 16:41:25 -0500 [thread overview]
Message-ID: <patchbomb.1326145285@xdev.gridcentric.ca> (raw)
- Disallow for good paging_prep: it's unsafe
- Allow paging in of a page in paged-out state. This shortcuts the
need to reference the page and trigger a populate event, thus saving
a complete control stack round-trip.
