Hi;
-rc6 fails with latest gcc 4.2 snapshot as following;
CC [M] drivers/kvm/svm.o
drivers/kvm/svm.c:206: warning: 'inject_db' defined but not used
drivers/kvm/svm.c: In function 'svm_vcpu_run':
drivers/kvm/kvm.h:560: error: 'asm' operand has impossible constraints
make[2]: *** [drivers/kvm/svm.o] Error 1
make[1]: *** [drivers/kvm] Error 2
make: *** [drivers] Error 2
And according to this thread http://lkml.org/lkml/2006/11/11/129, solution is
converting g to rm, patch follows
