Milk-V Jupiter Linux kernel
20dbad7525
commit a60dd06af674d3bb76b40da5d722e4a0ecefe650 upstream. irq_restore_affinity_of_irq() restarts managed interrupts unconditionally when the first CPU in the affinity mask comes online. That's correct during normal hotplug operations, but not when resuming from S3 because the drivers are not resumed yet and interrupt delivery is not expected by them. Skip the startup of suspended interrupts and let resume_device_irqs() deal with restoring them. This ensures that irqs are not delivered to drivers during the noirq phase of resuming from S3, after non-boot CPUs are brought back online.

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.
