_raw_spin_unlock_irqrestore
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit 991de2e59090e55c65a7f59a049142e3c480f7bd
Author: Jiang Liu <jiang.liu@...ux.intel.com>
AuthorDate: Wed Jun 10 16:54:59 2015 +0800
Commit: Bjorn Helgaas <bhelgaas@...gle.com>
CommitDate: Thu Jul 30 14:05:57 2015 -0500
PCI, x86: Implement pcibios_alloc_irq() and pcibios_free_irq()
To support IOAPIC hotplug, we need to allocate PCI IRQ resources on demand
and free them when not used anymore.
Implement pcibios_alloc_irq() and pcibios_free_irq() to dynamically
allocate and free PCI IRQs.
Remove mp_should_keep_irq(), which is no longer used.
