On compilation I get the following error.

../qemu-kvm.h:41: error: redefinition of 'kvm_log_tpr'
../qemu-kvm.h:41: error: previous definition of 'kvm_log_tpr' was here
make[2]: *** [i8259.o] Error 1
make[2]: Leaving directory
`/root/Download/software/tpr-opt-1/qemu/x86_64-softmmu'
make[1]: *** [subdir-x86_64-softmmu] Error 2
make[1]: Leaving directory `/root/Download/software/tpr-opt-1/qemu'
make: *** [qemu] Error 2

Any help would be appreciated. Thanks.
