They do not disable it. They only implement MSR which can allow you to disable it. If you want to stay with updated microcode and with HLE, just don't configure it as disabled.

Yes they have. The only conditionally disabled feature is xbegin/xend/xabort.

From the article:

> The other TSX sub-feature, Hardware Lock Elision (HLE), is unconditionally disabled by the new microcode...
