On RISC-V platforms, the RINTC structures should be probed before any other interrupt controller structures and IMSIC before APLIC. This order is established by using MADT sub table types which are ordered in the incremental order from the RINTC. So, add the architecture function for RISC-V to reorder the interrupt controller probing as per the hierarchy like below. ACPI_MADT_TYPE_RINTC = 24, ACPI_MADT_TYPE_IMSIC = 25, ACPI_MADT_TYPE_APLIC = 26, ACPI_MADT_TYPE_PLIC = 27 This means processing all RINTC structures (in the order of appearance in MADT), followed by IMSIC strucutre and then all APLIC/PLIC structures.

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.
