Michael S. Tsirkin wrote:
CONFIG_KVM_TRACE in kernel conflicts with the definition
in external module. external-module-compat-comm.h tried
to work around this, but this didn't work as some
code still does #include <linux/autoconf.h>
directly.
Solve this differently by s/CONFIG_KVM_TRACE/CONFIG_KMOD_KVM_TRACE/
in awk. Had to tighten regular expressions in hack-module.awk
so that they don't trigger on kvm_host.h .
