The commit a2055abe9c67 ("x86/mm: Pass flush_tlb_info to flush_tlb_others() etc") removed the unnecessary cpu parameter from uv_flush_tlb_others() but left an unused variable. arch/x86/mm/tlb.c: In function 'native_flush_tlb_others': arch/x86/mm/tlb.c:688:16: warning: variable 'cpu' set but not used [-Wunused-but-set-variable] unsigned int cpu; ^~~ Fixes: a2055abe9c67 ("x86/mm: Pass flush_tlb_info to flush_tlb_others() etc") Signed-off-by: Qian Cai <cai@lca.pw> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Andyt Lutomirski <luto@kernel.org> Cc: dave.hansen@linux.intel.com Cc: peterz@infradead.org Cc: bp@alien8.de Cc: hpa@zytor.com Link: https://lkml.kernel.org/r/20190228220155.88124-1-cai@lca.pw
