NAME

probe_irq_mask - scan a bitmap of interrupt lines  

SYNOPSIS

unsigned int probe_irq_mask (unsigned long val);  

ARGUMENTS

val
mask of interrupts to consider
 

DESCRIPTION

Scan the ISA bus interrupt lines and return a bitmap of active interrupts. The interrupt probe logic state is then returned to its previous value.  

NOTE

we need to scan all the irq's even though we will only return ISA irq numbers - just so that we reset them all to a known state.
