/*
* Disabling TSX is not a trivial business.
*
* First of all, there's a CPUID bit: X86_FEATURE_RTM_ALWAYS_ABORT
* which says that TSX is practically disabled (all transactions are
* aborted by default). When that bit is set, the kernel unconditionally
* disables TSX.
*
* In order to do that, however, it needs to dance a bit:
*
* 1. The first method to disable it is through MSR_TSX_FORCE_ABORT and
* the MSR is present only when *two* CPUID bits are set:
*
* - X86_FEATURE_RTM_ALWAYS_ABORT
* - X86_FEATURE_TSX_FORCE_ABORT
*
* 2. The second method is for CPUs which do not have the above-mentioned
* MSR: those use a different MSR - MSR_IA32_TSX_CTRL and disable TSX
* through that one. Those CPUs can also have the initially mentioned
* CPUID bit X86_FEATURE_RTM_ALWAYS_ABORT set and for those the same strategy
* applies: TSX gets disabled unconditionally.
*
* When either of the two methods are present, the kernel disables TSX and
* clears the respective RTM and HLE feature flags.
*
* An additional twist in the whole thing presents late microcode loading
* which, when done, may cause for the X86_FEATURE_RTM_ALWAYS_ABORT CPUID
* bit to be set after the update.
*
* A subsequent hotplug operation on any logical CPU except the BSP will
* cause for the supported CPUID feature bits to get re-detected and, if
* RTM and HLE get cleared all of a sudden, but, userspace did consult
* them before the update, then funny explosions will happen. Long story
* short: the kernel doesn't modify CPUID feature bits after booting.
*
* That's why, this function's call in init_intel() doesn't clear the
* feature flags.
