Marc Zyngier c9f43423c4 arm64: entry: factor irq triage logic into macros 
[ Upstream commit 9eb563cdab ]

In subsequent patches we'll allow an FIQ handler to be registered, and
FIQ exceptions will need to be triaged very similarly to IRQ exceptions.
So that we can reuse the existing logic, this patch factors the IRQ
triage logic out into macros that can be reused for FIQ.

The macros are named to follow the elX_foo_handler scheme used by the C
exception handlers. For consistency with other top-level exception
handlers, the kernel_entry/kernel_exit logic is not moved into the
macros. As FIQ will use a different C handler, this handler name is
provided as an argument to the macros.

There should be no functional change as a result of this patch.

README 

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.
