If you fix the issue, kindly add following tag where applicable

Note: the linux-next/master HEAD 036ad6daa8f0fd357af7f50f9da58539eaa6f68c builds fine.
       It may have been fixed somewhere.

All errors (new ones prefixed by >>):

    lib/x86_64/processor.c: In function 'vm_xsave_req_perm':
lib/x86_64/processor.c:636:25: error: 'KVM_X86_XCOMP_GUEST_SUPP' undeclared (first use in this function)

This is because the kernel headers have to be installed first
now.  So this command needs to be added:

Hi Guillaume,

Thanks for your guidance, we have added the command to the CI.

Best Regards,
Rong Chen

     make O=/tmp/kselftest headers

before running this one:

     make O=/tmp/kselftest -C tools/testing/selftests
