[ Impact ]

BHI_AUTO only mitigates newer systems. Upstream removed that option.
This change makes the config match the newer Ubuntu kernels (and upstream).

[ Test Case ]

Compile tested only.

[ Where Problems Could Occur ]

What could possibly go wrong with any spectre mitigation...? The usual kernel crashes and/or
call traces at boot.

Juerg Haefliger (1):
  UBUNTU: [Config] Set SPECTRE_BHI_ON=y
