Change the outer macro to use __tmp. Avoids a sparse warning like the following at every call site of __emulate_2op arch/x86/kvm/x86_emulate.c:1091:3: warning: symbol '_tmp' shadows an earlier one arch/x86/kvm/x86_emulate.c:1091:3: originally declared here [18 more warnings suppressed] Signed-off-by: Harvey Harrison Signed-off-by: Avi Kivity --- diff --git a/arch/x86/kvm/x86_emulate.c b/arch/x86/kvm/x86_emulate.c index cacdcf5f32d7..f59ed93f5d24 100644 --- a/arch/x86/kvm/x86_emulate.c +++ b/arch/x86/kvm/x86_emulate.c @@ -371,7 +371,7 @@ static u16 group2_table[] = { #define __emulate_2op(_op,_src,_dst,_eflags,_bx,_by,_wx,_wy,_lx,_ly,_qx,_qy) \ do { \ - unsigned long _tmp; \ + unsigned long __tmp; \ switch ((_dst).bytes) { \ case 1: \ __asm__ __volatile__ ( \ @@ -379,7 +379,7 @@ static u16 group2_table[] = { _op"b %"_bx"3,%1; " \ _POST_EFLAGS("0", "4", "2") \ : "=m" (_eflags), "=m" ((_dst).val), \ - "=&r" (_tmp) \ + "=&r" (__tmp) \ : _by ((_src).val), "i" (EFLAGS_MASK)); \ break; \ default: \
