Short-circuiting the build by hard-disabling X86_FEATURE_INVLPGB, or even adding an explicit if(!IS_ENABLED(CONFIG_X86_BROADCAST_TLB_FLUSH)) is not enough to get the compiler to short-circuit the rest of the code in that function. We might need an #ifdef inside destroy_context_free_global_asid as well, no good way to move that one into a .h file without making the global asid data structures in tlb.c visible to the entire kernel instead of keeping them static in tlb.c --=20 All Rights Reversed.
