ibrs can't be enabled on no ibrs cpu ( #195 )
...
* ibrs can't be enabled on no ibrs cpu
If the cpu is identified, and does not support SPEC_CTRL or IBRS, then ibrs can't be enabled, even if supported by the kernel.
Instead of reporting IBRS enabled and active UNKNOWN, report IBRS enabled and active NO.

cpuid and msr module check
...
This adds a check before loading the cpuid and msr modules under linux, ensuring they are not unloaded in exit_cleanup() if they were initially present.
