LKP/0Day reported some building errors about kvm, and errors message are not always same: - lib/x86_64/processor.c:1083:31: error: ‘KVM_CAP_NESTED_STATE’ undeclared (first use in this function); did you mean ‘KVM_CAP_PIT_STATE2’? - lib/test_util.c:189:30: error: ‘MAP_HUGE_16KB’ undeclared (first use in this function); did you mean ‘MAP_HUGE_16GB’?
Although kvm relies on the khdr, they still be built in parallel when -j is specified. In this case, it will cause compiling errors.
Here we mark target khdr as NOTPARALLEL to make it be always built first.
