Subject: PCI: host: Mark PCIe/PCI (MSI) cascade ISR as IRQF_NO_THREAD
Git-commit: 3eefa790c9681a2dcbc923542dcd85b6989e8855
Patch-mainline: v4.13-rc1
References: fate#326536, fate#326532
Similar as commit 8ff0ef996ca0 ("PCI: host: Mark PCIe/PCI (MSI) IRQ cascade
handlers as IRQF_NO_THREAD"), we should mark PCIe/PCI (MSI) IRQ cascade
handlers in designware, qcom, and vmd as IRQF_NO_THREAD explicitly.
