[PATCH 0/2] migration/postcopy: map tmp and large zero page in setup stage

Posted by Wei Yang 6 years, 1 month ago

Currently we map these page when we want to use it, while this may be a
little late.

To make the code consistency, these two patches move the map into
postcopy_ram_incoming_setup.

Wei Yang (2):
  migration/postcopy: allocate tmp_page in setup stage
  migration/postcopy: map large zero page in
    postcopy_ram_incoming_setup()
