From c7b9095e87bf81f029fbae2e5d6a8354b6f11987 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Wed, 27 Jan 2021 12:52:16 +0000 Subject: arm64: Include linux/io.h in mm/mmap.c Commit 507d664450f8 ("arm64: mm: Remove unused header file") removed a bunch of apparently "unused" header inclusions from our mm/mmap.c implementation, but in doing so introduced the following warning when building with W=1: >> arch/arm64/mm/mmap.c:17:5: warning: no previous prototype for 'valid_phys_addr_range' [-Wmissing-prototypes] 17 | int valid_phys_addr_range(phys_addr_t addr, size_t size) | ^~~~~~~~~~~~~~~~~~~~~ >> arch/arm64/mm/mmap.c:36:5: warning: no previous prototype for 'valid_mmap_phys_addr_range' [-Wmissing-prototypes] 36 | int valid_mmap_phys_addr_range(unsigned long pfn, size_t size) | ^~~~~~~~~~~~~~~~~~~~~~~~~~ Add back the linux/io.h header inclusion to pull in the missing prototypes.
