Subject: [PATCH 0 of 8] x86/mm fixes
Date: Wed, 25 Jan 2012 22:53:24 -0500 [thread overview]
Message-ID: <patchbomb.1327550004@xdev.gridcentric.ca> (raw)
This patch series aggregates a number of fixes:
- Fix the paging load operation to correct the m2p entry, and
promote the p2m entry to the final guest-accessible type
- Fix locking around p2m_teardown
- Fix read-only mapping of shared pages
- Output to the console the per-domain count of shared pages
- Eliminate a stale var from a p2m audit debugtrace printk
- Correct accounting of paged out pages when a paging-out is
interrupted by a guest access
- Simplify (and in some cases eliminate) use of p2m get_gfn*_unlocked
- Allow for recursive locking in the mm-locks.h deadlock detection
scheme
Patches 1, 4 and 6 involve paging, cc'ed Olaf Hering.
Patches 2, 7 and 8 lay more groundwork in preparation of fully
synchronized p2m access.
