In commit 721255b9826b ("genirq: Use a maple tree for interrupt> > Fixes: 721255b9826b ("genirq: Use a maple tree for interrupt descriptor management")
descriptor management"), the irq_desc_tree was replaced with a
sparse_irqs tree using a maple tree structure. In the interest of
providing both a minimal bugfix as well as something that is unlikely to
break in the future, invoke the irq_to_desc() function directly from
within GDB in order to obtain the interrupt number. This requires us to
handle the gdb.error exception to continue walking the tree.
