NR_MAX_IRQS is defined as 272 and IRQ_INVALID as 273 which implies that 272 is a valid irq number. In this case, an illegal access can occur at run time when irq_desc_array[] or irq_count[] is accessed with index 272. This fix stops the illegal access by renaming NR_MAX_IRQS to NR_IRQS and then places proper conditions for range checks. If the index is >= NR_IRQS, then index is invalid otherwise its considered valid for accessing irq arrays. IRQ_INVALID definition is also changed to 0xffffffffU to indicate maximum unsigned value.

Embedded-Hypervisor ################### This open source embedded hypervisor defines a software architecture for running multiple software subsystems managed securely on a consolidated system (by means of a virtual machine manager), and defines a reference framework Device Model implementation for devices emulation This embedded hypervisor is type-1 reference hypervisor, running directly on the system hardware. It can be used for building software defined cockpit (SDC) or In-Vehicle Experience (IVE) solutions running on Intel Architecture Apollo Lake platforms. As a reference implementation, it provides the basis for embedded hypervisor vendors to build solutions with an open source reference I/O mediation solution, and provides auto makers a reference software stack for SDC usage. This embedded hypervisor is able to support both Linux* and Android* as a Guest OS, managed by the hypervisor, where applications can run. This embedded hypervisor is a partitioning hypervisor reference stack, also suitable for non-automotive IoT & embedded device solutions. It will be addressing the gap that currently exists between datacenter hypervisors, hard partitioning hypervisors, and select industrial applications. Extending the scope of this open source embedded hypervisor relies on the involvement of community developers like you!
