Subject[PATCH v5 2/3] memblock: add memblock_free() alloc when CONFIG_HAVE_MEMBLOCK is not set
From: Frank Rowand <>

When CONFIG_HAVE_MEMBLOCK is not set, an error version of
memblock_alloc() exists. Add the matching memblock_free().

Signed-off-by: Frank Rowand <>

Andrew or Michal, can you please ack this patch to be accepted
by Rob?

With "of: add early boot allocation of
of_find_node_by_phandle() cache" applied, kbuild test robot reports
tilex architecture build error due to no prototype for memblock_free().

The version of the patch that kbuild test robot reported was
"[PATCH v4 2/2] of: add early boot allocation of
of_find_node_by_phandle() cache". An updated version of that
patch is now patch 3/3 of this series.
