From 30c8f4e411fb76f752a193bd945d4b9ef06c2d87 Mon Sep 17 00:00:00 2001 From: Serge Semin Date: Fri, 3 May 2019 20:50:37 +0300 Subject: 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.
