[Bug 103731] [DRM/i915][Bisected] Kernel panic in setup_vector_irq() with HDMI LPE driver while putting offline CPU thread back to online

--- Comment #4 from Augustine Chen <augustine.chen at intel.com> ---
Two findings here...
The first is there is no well-recognized chip_data of HDMI LPE audio IRQ which
makes x86 APIC driver try to handle a invalid pointer and then causes kernel
panic.
The second is to disable CONFIG_CPUMASK_OFFSTACK to make cpumask_var_t be an
array type. Then nothing about invalid pointer in x86 APIC driver will happen.
