Regressions :-(

Tests which did not succeed and are blocking:

    libxc: obtain correct length of p2m during core dumping
    
    while implementing core dumping functionality for the libxl driver
    of libvirt, I discovered an issue with mapping pages of a pv guest.
    
    After dumping the core of a pv guest the domain was not cleared up
    properly and some pages were not unmapped. This issue is similar
    to the one reported here:
    http://lists.xensource.com/archives/html/xen-devel/2011-05/msg01314.html
    
    In xc_domain_dumpcore_via_callback in the file xc_core.c the function
    xc_core_arch_map_p2m is called to map P2M_FL_ENTRIES pages to the
    variable p2m.
    But to unmap the pages later, the dinfo->p2m_size has to be set
    accordingly.
    This was not done, instead a variable named p2m_size was set.
    This way P2M_FL_ENTRIES was always zero and the pages were left
    mapped.

    libxc: after saving, unmap correct amount for live_m2p
    
    With some help from Olaf, I've finally got to the bottom of an issue I
    came across while trying to implement save/restore in the libvirt
    libxenlight driver.  After issuing the save operation, the saved
    domain was not being cleaned up properly and left in this state from
    xl's perspective
    
    xen33:# xl list
    Name                   ID   Mem VCPUs      State   Time(s)
    Domain-0                0  6821     8     r-----     122.5
    (null)                  2     2     2     --pssd      10.8
    
    Checking the libvirtd /proc/$pid/maps I found this
    
    7f3798984000-7f3798b86000 r--s 00002000 00:03 4026532097
    /proc/xen/privcmd
    
    So not all all pages belonging to the domain were unmapped from
    libvirtd.  In tools/libxc/xc_domain_save.c we found that
    P2M_FL_ENTRIES were being mapped but only P2M_FLL_ENTRIES were being
    unmapped.  The attached patch changes the unmapping to use the same
    P2M_FL_ENTRIES macro.  I'm not too familiar with this code though so
    posting here for review.
    
    I suspect this was not noticed before since most (all?) processes
    doing save terminate after the save and are not long-running like
    libvirtd.

    This change should be backported to relevant earlier trees. -iwj
