| Subject: powerpc/64s: Include cpu header |
| |
| From: Breno Leitao <leitao@debian.org> |
| |
| commit 42e2acde1237878462b028f5a27d9cc5bea7502c upstream. |
| |
| Current powerpc security.c file is defining functions, as |
| cpu_show_meltdown(), cpu_show_spectre_v{1,2} and others, that are being |
| declared at linux/cpu.h header without including the header file that |
| contains these declarations. |
| |
| This is being reported by sparse, which thinks that these functions are |
| static, due to the lack of declaration: |
| |
| arch/powerpc/kernel/security.c:105:9: warning: symbol 'cpu_show_meltdown' was not declared. Should it be static? |
| arch/powerpc/kernel/security.c:139:9: warning: symbol 'cpu_show_spectre_v1' was not declared. Should it be static? |
| arch/powerpc/kernel/security.c:161:9: warning: symbol 'cpu_show_spectre_v2' was not declared. Should it be static? |
| arch/powerpc/kernel/security.c:209:6: warning: symbol 'stf_barrier' was not declared. Should it be static? |
| arch/powerpc/kernel/security.c:289:9: warning: symbol 'cpu_show_spec_store_bypass' was not declared. Should it be static? |
| |
| This patch simply includes the proper header (linux/cpu.h) to match |
| function definition and declaration. |
