The problem of this issue is due to commit db616173d787 ("x86/tsx: Add config options to set tsx=on|off|auto"), which sets the default to "off" for 100% safety.

Considering that disabling TSX is a policy decision likely to be taken by the OS vendor or by the system administrator, we could at least make the CPU model easier to use on those cases.
