From 42b46aeff2e366bad54bd1c069b7b5381d9be8b3 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Mon, 11 Mar 2019 23:29:31 -0700 Subject: [PATCH] memblock: drop __memblock_alloc_base() The __memblock_alloc_base() function tries to allocate a memory up to the limit specified by its max_addr parameter. Depending on the value of this parameter, the __memblock_alloc_base() can is replaced with the appropriate memblock_phys_alloc*() variant.
