+
+- Page migration requires the use of swap handles to preserve the
+  information of the anonymous page table entries. This means that swap
+  space is reserved but never used. The maximum number of swap handles used
+  is determined by CHUNK_SIZE (see mm/mempolicy.c) per ongoing migration.
+  Reservation of pages could be avoided by having a special type of swap
+  handle that does not require swap space and that would only track the page
+  references. Something like that was proposed by Marcelo Tosatti in the
+  past (search for migration cache on lkml or linux-mm@kvack.org).
 
-19. The locks are dropped from the old and new page.
+- Page migration unmaps ptes for file backed pages and requires page
+  faults to reestablish these ptes. This could be optimized by somehow

+  However, there are several locking challenges that have to be overcome
+  before this is possible.
 
-20. The new page is moved to the LRU.
+- Page migration generates read ptes for anonymous pages. Dirty page
+  faults are required to make the pages writable again. It may be possible
+  to generate a pte marked dirty if it is known that the page is dirty and
+  that this process has the only reference to that page.

           EDAC is designed to report errors in the core system.
           These are low-level errors that are reported in the CPU or
           supporting chipset: memory errors, cache errors, PCI errors,
           thermal throttling, etc..  If unsure, select 'Y'.
 
+          If this code is reporting problems on your system, please
+          see the EDAC project web pages for more information at:
+
+          <http://bluesmoke.sourceforge.net/>
+
+          and:
+
+          <http://buttersideup.com/edacwiki>
+
+          There is also a mailing list for the EDAC project, which can
+          be found via the sourceforge page.
