I'm trying to compile a device driver on newer kernel and either the
interface to rdtsc has changed is some way
since I was updated my kernel or I've got some other problem, anyway
baffled by this and hopefully there is some
obvious numpty error someone can point out:

I'm not using rdtsc in my driver. To me this looks like the code is
msr.h is choking something
else in the kernel headers and that it has sfa to do with my driver.
Problem occurs for kernel > 4.4.0-32 possibly older
No problem on k<=3.13.0.

Hi,
I am having the same problem with the pi_stage kernel module, using
kernel v5.0.0-37, how did you solve your problem?
Thanks,
Will
