GENERIC_IRQ_MULTI_HANDLER is incompatible with MULTI_IRQ_HANDLER because they define the same symbols. Multiple generic irqchip drivers select MULTI_IRQ_HANDLER, which is now defined on all architectures that provide set_handle_irq(). To solve this select GENERIC_IRQ_MULTI_HANDLER for all drivers that used to select MULTI_IRQ_HANDLER, but only when MULTI_IRQ_HANDLER doesn't exist. After that every architecture can be converted over from MULTI_IRQ_HANDLER to GENERIC_IRQ_MULTI_HANDLER before removing the extra MULTI_IRQ_HANDLER scaffolding.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
