The last user of arch_irq_handler_default is gone now, so the entry-macro-multi.S file and all references to mach/entry-macro.S can be removed, as well as the asm_do_IRQ() entrypoint into the interrupt handling routines implemented in C. Note: The ARMv7-M entry still uses its own top-level IRQ entry, calling nvic_handle_irq() from assembly. This could be changed to go through generic_handle_arch_irq() as well, but it's unclear to me if there are any benefits.
