From 523d0fb4f05dcefed59c6325acb54adc34ee4c2d Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Mon, 14 Nov 2016 14:04:43 -0500 Subject: [PATCH] x86/percpu: Remove unnecessary include of module.h, add asm/desc.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This was originally a part of commit 186f43608a5c: ("x86/kernel: Audit and remove any unnecessary uses of module.h") ...but without the asm/desc.h addition. As such, Ingo reported a build failure on i386 allnoconfig with SMP=y during his pre-merge testing. For expediency the chunk was just dropped at that time. The failure was as follows: arch/x86/kernel/setup_percpu.c: In function ‘setup_percpu_segment’: arch/x86/kernel/setup_percpu.c:159:2: error: implicit declaration of function ‘pack_descriptor’ [-Werror=implicit-function-declaration] arch/x86/kernel/setup_percpu.c:162:2: error: implicit declaration of function ‘write_gdt_entry’ [-Werror=implicit-function-declaration] arch/x86/kernel/setup_percpu.c:162:18: error: implicit declaration of function ‘get_cpu_gdt_table’ [-Werror=implicit-function-declaration] As pack_descriptor(), write_gdt_entry() and get_cpu_gdt_table() all live in the file arch/x86/include/asm/desc.h -- calling that header out explicitly should fix things.
