Subject: [PATCH v2 0/3] use bin_attribute to avoid buff overflow

patch #1 adds a new function cpumap_print_to_buf and patch #2 uses
this function in drivers/base/topology.c, and patch #3 uses this new
function in drivers/base/node.c.

v2:
split the original patch #1 into two patches and use kasprintf() in
patch #1 to simplify the code. do some minor formatting adjustments.

Tian Tao (3):
  lib: bitmap: introduce bitmap_print_to_buf
  topology: use bin_attribute to avoid buff overflow
  drivers/base/node.c: use bin_attribute to avoid buff overflow
