From 90db7b220c9aea91948e82d51b99514f9398f9b5 Mon Sep 17 00:00:00 2001 From: David Abdurachmanov Date: Tue, 22 Oct 2019 19:21:35 +0300 Subject: riscv: fix fs/proc/kcore.c compilation with sparsemem enabled Failed to compile Fedora/RISCV kernel (5.4-rc3+) with sparsemem enabled: fs/proc/kcore.c: In function 'read_kcore': fs/proc/kcore.c:510:8: error: implicit declaration of function 'kern_addr_valid'; did you mean 'virt_addr_valid'? [-Werror=implicit-function-declaration] 510 | if (kern_addr_valid(start)) { | ^~~~~~~~~~~~~~~ | virt_addr_valid Looking at other architectures I don't see kern_addr_valid being guarded by CONFIG_FLATMEM.
