From: Luciano Leão <lucianorsleao@gmail.com> stable inclusion from stable-v5.10.150 commit 1ef5798638bd2389c25ff784fb4c64e2cd2ec077 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0XA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 30ea703a38ef76ca119673cd8bdd05c6e068e2ac ] Include the header containing the prototype of init_ia32_feat_ctl(), solving the following warning: $ make W=1 arch/x86/kernel/cpu/feat_ctl.o arch/x86/kernel/cpu/feat_ctl.c:112:6: warning: no previous prototype for ‘init_ia32_feat_ctl’ [-Wmissing-prototypes] 112 | void init_ia32_feat_ctl(struct cpuinfo_x86 *c) This warning appeared after commit 5d5103595e9e5 ("x86/cpu: Reinitialize IA32_FEAT_CTL MSR on BSP during wakeup") had moved the function init_ia32_feat_ctl()'s prototype from arch/x86/kernel/cpu/cpu.h to arch/x86/include/asm/cpu.h. Note that, before the commit mentioned above, the header include "cpu.h" (arch/x86/kernel/cpu/cpu.h) was added by commit 0e79ad863df43 ("x86/cpu: Fix a -Wmissing-prototypes warning for init_ia32_feat_ctl()") solely to fix init_ia32_feat_ctl()'s missing prototype. So, the header include "cpu.h" is no longer necessary.
