Currently we call irq_set_noprobe() in a loop for all IRQs, but indeed it only works for IRQs below NR_IRQS_LEGACY because at init_IRQ() only legacy interrupts have been allocated. Instead, we can define ARCH_IRQ_INIT_FLAGS as IRQ_NOPROBE in asm/hwirq.h and the core will automatically set the flag for all interrupts.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
