0e440cbac6 enh: detect IPBP return predictor bypass in Inception/SRSO ("PB-Inception") (#500)
AMD Zen 1-3 CPUs don't flush return predictions on IBPB, allowing
cross-process Spectre attacks even with IBPB-on-entry active. The kernel
fix (v6.12+, backported) adds RSB fill after IBPB on affected CPUs.
Detect this gap by checking CPUID IBPB_RET bit and kernel ibpb_no_ret
bug flag, and flag systems relying on IBPB without the RSB fill fix.
