[PATCH v4 8/9] x86/nmi: Simplify offline microcode handler invocation

[Chang S. Bae]

The microcode loader now uses the stop-machine facility for NMI-based
loading. The offline handler is the only remaining user of the microcode
NMI static key.

The handler already checks whether it is enabled, and how fast an offline
CPU handles the NMI does not matter. Instead of the static key, check the
build option.
