Pull irq fixes from Thomas Gleixner: "A rather large update after the kaisered maintainer finally found time to handle regression reports. - The larger part addresses a regression caused by the x86 vector management rework. The reservation based model does not work reliably for MSI interrupts, if they cannot be masked (yes, yet another hw engineering trainwreck). The reason is that the reservation mode assigns a dummy vector when the interrupt is allocated and switches to a real vector when the interrupt is requested. If the MSI entry cannot be masked then the initialization might raise an interrupt before the interrupt is requested, which ends up as spurious interrupt and causes device malfunction and worse. The fix is to exclude MSI interrupts which do not support masking from reservation mode and assign a real vector right away. - Extend the extra lockdep class setup for nested interrupts with a class for the recently added irq_desc::request_mutex so lockdep can differeniate and does not emit false positive warnings. - A ratelimit guard for the bad irq printout so in case a bad irq comes back immediately the system does not drown in dmesg spam" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: genirq/msi, x86/vector: Prevent reservation mode for non maskable MSI genirq/irqdomain: Rename early argument of irq_domain_activate_irq() x86/vector: Use IRQD_CAN_RESERVE flag genirq: Introduce IRQD_CAN_RESERVE flag genirq/msi: Handle reactivation only on success gpio: brcmstb: Make really use of the new lockdep class genirq: Guard handle_bad_irq log messages kernel/irq: Extend lockdep class for request mutex
