fix(interrupts): save and restore priority mask To simplify secure interrupt handling, the threshold for interrupts was changed by modifying the priority mask without saving the current value of priority mask. This led to overriding of original priority mask. This patch performs save and restore of priority mask at appropriate times. Please note the current design makes the assumption that the target vCPU of a secure interrupt is pinned to the same physical CPU on which the secure interrupt triggered. The target vCPU has to be resumed on the current CPU in order for it to service the virtual interrupt. This design limitation simplifies the interrupt management implementation in SPMC.
