commit 25af8e6b6106f47f5ee276545fcab47cefa67ba1
Merge: 3585895 dc54e25
Author: Peter Maydell <peter.maydell@xxxxxxxxxx>
Date:   Tue Jul 22 12:03:44 2014 +0100

    Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into 
staging
    
    One of the two pending migration fix, and a small KVM patch.

commit dc54e2525389e903cee2b847cf761b5d857f75cb
Author: Chen Gang <gang.chen.5i5j@xxxxxxxxx>
Date:   Sat Jul 19 09:21:46 2014 +0800

    kvm-all: Use 'tmpcpu' instead of 'cpu' in sub-looping to avoid 'cpu' be NULL
    
    If kvm_arch_remove_sw_breakpoint() in CPU_FOREACH() always be fail, it
    will let 'cpu' NULL. And the next kvm_arch_remove_sw_breakpoint() in
    QTAILQ_FOREACH_SAFE() will get NULL parameter for 'cpu'.
    
    And kvm_arch_remove_sw_breakpoint() can assumes 'cpu' must never be NULL,
    so need define additional temporary variable for 'cpu' to avoid the case.

commit 6886867e9880830d735d8ae6f6cc63ed9eb2be0c
Author: Paolo Bonzini <pbonzini@xxxxxxxxxx>
Date:   Mon Jul 21 16:45:18 2014 +0200

    exec: fix migration with devices that use address_space_rw
    
    Devices that use address_space_rw to write large areas to memory
    (as opposed to address_space_map/unmap) were broken with respect
    to migration since fe680d0 (exec: Limit translation limiting in
    address_space_translate to xen, 2014-05-07).  Such devices include
    IDE CD-ROMs.
    
    The reason is that invalidate_and_set_dirty (called by address_space_rw
    but not address_space_map/unmap) was only setting the dirty bit for
    the first page in the translation.
    
    To fix this, introduce cpu_physical_memory_set_dirty_range_nocode that
    is the same as cpu_physical_memory_set_dirty_range except it does not
    muck with the DIRTY_MEMORY_CODE bitmap.  This function can be used if
    the caller invalidates translations with tb_invalidate_phys_page_range.
    
    There is another difference between cpu_physical_memory_set_dirty_range
    and cpu_physical_memory_set_dirty_flag; the former includes a call
    to xen_modified_memory.  This is handled separately in
    invalidate_and_set_dirty, and is not needed in other callers of
    cpu_physical_memory_set_dirty_range_nocode, so leave it alone.
    
    Just one nit: now that invalidate_and_set_dirty takes care of handling
    multiple pages, there is no need for address_space_unmap to wrap it
    in a loop.  In fact that loop would now be O(n^2).
