From 397dc00e249ec64e106374565575dd0eb7e25998 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Mon, 16 Sep 2019 14:13:10 +0300 Subject: mips: sgi-ip27: switch from DISCONTIGMEM to SPARSEMEM The memory initialization of SGI-IP27 is already half-way to support SPARSEMEM. It only had free_bootmem_with_active_regions() left-overs interfering with sparse_memory_present_with_active_regions(). Replace these calls with simpler memblocks_present() call in prom_meminit() and adjust arch/mips/Kconfig to enable SPARSEMEM and SPARSEMEM_EXTREME for SGI-IP27.
