[PATCH 1/6] x86/Documentation/kernel-parameters.txt: Add wakeup_cpu_via_init kernel parameter help

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@xxxxxxxxx>

The new kernel parameter wakeup_cpu_via_init overrides mwait or nmi method and
forces to wake up offline CPU via INIT, INIT, STARTUP sequence. This is useful
in RAS when a temporary CPU error could be fixed by INIT.
