Linux Interrupt Context maps to ARM CPSR.mode = IRQ

Hi,
As per a lot of linux documentation some components work in process
context and some work in interrupt context.
If we try to map these contexts to ARM processor modes then is it
safely to assume that
Process Context : CPSR.mode = SVC
Interrupt Context : CPSR.mode = IRQ
If not how to define interrupt context properly. Confusing at times.
