Each patch is independent. Apart from mapping and unmapping page tables, no other functional change intended. --- Changed in v2: - I kept UNMAP_DOMAIN_PAGE() for now in v2, but I if people say in some cases it is an overkill and unmap_domain_page() should be used, I am okay with that and can make the change. - code cleanup and style fixes. - unmap as early as possible.
