x86: fix typo in filter_cpuid_features()
Impact: fix wrong disabling of cpu features
an amd system got this strange output:
CPU: CPU feature monitor disabled due to lack of CPUID level 0x5
but in /proc/cpuinfo I have:
cpuid level : 5
on intel system:
CPU: CPU feature monitor disabled due to lack of CPUID level 0x5
CPU: CPU feature dca disabled due to lack of CPUID level 0x9
but in /proc/cpuinfo i have:
cpuid level : 11
Tt turns out there is a typo, and we should use level member in df.
