Under some conditions, MONITOR wakeups on Lunar Lake processors can be lost, resulting in significant user-visible delays.
Add LunarLake to X86_BUG_MONITOR so that wake_up_idle_cpu() always sends an IPI, avoiding this potential delay.
This kinda implies that X86_BUG_MONITOR only does one thing. What about the two other places in the tree that check it. Are those relevant?

This obviously conflicts with the VFM infrastructure, but shouldn't this also get backported to even older stable kernels?
I thought the "# 6.11" was to tell folks where it is *needed*, not where it actually applies.
