Commitb00bee8afa("irqchip: Convert generic irqchip locking to guards") replaced calls to irq_gc_lock_irq{save,restore}() with guard(raw_spinlock_irq). However, in irq-atmel-aic5.c and irq-atmel-aic.c, the xlate callback is used in the early boot process, before interrupts are initially enabled. As its destructor enables interrupts, this triggers the warning in start_kernel(): WARNING: CPU: 0 PID: 0 at init/main.c:1024 start_kernel+0x4d0/0x5dc Interrupts were enabled early Fix this by using guard(raw_spinlock_irqsave) instead.

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.
