Subject: [PATCH v2 1/5] mips: Dump memblock regions for debugging

It is useful to have the whole memblock memory space printed to console
when basic memlock initializations are done. It can be performed by
ready-to-use method memblock_dump_all(), which prints the available
and reserved memory spaces if memblock=debug kernel parameter is
specified. Lets call it at the very end of arch_mem_init() function,
when all memblock memory and reserved regions are defined, but before
any serious allocation is performed.

Signed-off-by: Serge Semin <>

Changelog v2
- Reword commit message since memblock debug printout is activated by
  memblock=debug kernel parameter
