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.

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 Restructured Text 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.
