From b10d6bca87204cdafd0cd7aaa837ad30b4eb8c20 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Tue, 13 Oct 2020 16:58:08 -0700 Subject: arch, drivers: replace for_each_membock() with for_each_mem_range() There are several occurrences of the following pattern: for_each_memblock(memory, reg) { start = __pfn_to_phys(memblock_region_memory_base_pfn(reg); end = __pfn_to_phys(memblock_region_memory_end_pfn(reg)); /* do something with start and end */ } Using for_each_mem_range() iterator is more appropriate in such cases and allows simpler and cleaner code.
