[Xen-devel] [v3 00/10] PML (Page Modification Logging) support

[Kai Huang <kai.huang@xxxxxxxxxxxxxxx>]

v2->v3:

- Merged v2 patch 02 (document change) to patch 01 as a single patch, and
  changed new parameter description as suggested by Andrew.
- changed vmx_vcpu_flush_pml_buffer to call mark_dirty for all logged GFNs, and
  call p2m_change_type_one regardless of return value.
- Added ASSERT for vcpu (being current, or being non-running and unrunnable) to
  vmx_vcpu_flush_pml_buffer
- Other refinement in coding style, comments description, etc.

Sanity test of live migration has been tested both with and without PML.
