Stéphane Lesimple f34dd5fa7b enh: assume CPU is immune to Zenbleed regardless of vendor except AMD 
This contradicts our usual "if we don't know, consider vulnerable" motto,
but as this vuln is extremely specific (which is not the case for the Spectre
range of vulnerabilities, for example), this is the correct approach here.

Stéphane Lesimple 18df38fae6 fix: sgx: on locked down kernels, fallback to CPUID bit for detection 
on locked down kernels (Fedora / Red Hat feature that prevents writing
to MSRs from userspace, even if root), we can't write to FLUSH_CMD MSR
to verify that it's present. So fallback to checking the existence of
the L1D flush CPUID feature bit to infer that the microcode has been
updated in a recent enough version that also mitigates SGX (fixes for
both issues have been included in the same microcode updates for all
Intel CPUs)
