s390/irq: improve displayed interrupt order in /proc/interrupts
Rework the irqclass_main_desc and irqclass_sub_desc data structures which are used to report detaild IRQ statistics in /proc/interrupts. When called from the procfs ops, the entries in the structures are processed one by one. The index of an IRQ in the structures is identical to its definition in the "enum interruption_class". To control and (re)order the displayed sequence, introduce an irq member in each entry. This helps to display related IRQs together without changing the assigned number in the interruption_class enumeration. That means, adding and displaying new IRQs are independent. Finally, this new behavior improves to maintain a kernel ABI. Signed-off-by: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
