[PATCH] x86-64: Make noirqdebug_setup function non init to fix modpost warning

o noirqdebug_setup() is __init but it is being called by
  quirk_intel_irqbalance() which if of type __devinit. If CONFIG_HOTPLUG=y,
  quirk_intel_irqbalance() is put into text section and it is wrong to
  call a function in __init section.

o MODPOST flags this on i386 if CONFIG_RELOCATABLE=y

WARNING: vmlinux - Section mismatch: reference to .init.text:noirqdebug_setup from .text between 'quirk_intel_irqbalance' (at offset 0xc010969e) and 'i8237A_suspend'

o Make noirqdebug_setup() non-init.
