Linux 6.10 Adds Support For Posted Interrupts On Bare Metal Hardware

Merged as part of the IRQ changes for the in-development Linux 6.10 kernel is support for posted interrupts on bare metal hardware. The notification interrupt then demultiplexes the pending bits in a memory based bitmap and invokes the corresponding device specific handlers. As this is only relevant for high end servers with multiple device queues per CPU attached and counterproductive for situations where interrupts are arriving at distinct times, the functionality is opt-in via a kernel command line parameter."
