Subject: [x86, irq] BUG: unable to handle kernel
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/jiangliu/linux.git irqdomain/p3v1
commit f0cff632d14bd3c01a8ec7ad0d5fe4f7cafa88fe
Author: Jiang Liu <jiang.liu@...ux.intel.com>

x86, irq: Convert IOAPIC to use hierarchy irqdomain interfaces
Convert IOAPIC driver to support and use hierarchy irqdomain interfaces.
It's a little big, but it always break bisectings if we split it into
multiple patches.
