Both these patches are already in the mainline kernel.

    arm_pmu: acpi: Add a representative platform device for TRBE
    
    ACPI TRBE does not have a HID for identification which could create and add
    a platform device into the platform bus. Also without a platform device, it
    cannot be probed and bound to a platform driver.
    
    This creates a dummy platform device for TRBE after ascertaining that ACPI
    provides required interrupts uniformly across all cpus on the system. This
    device gets created inside drivers/perf/arm_pmu_acpi.c to accommodate TRBE
    being built as a module.

    arm_pmu: acpi: Refactor arm_spe_acpi_register_device()
    
    Sanity checking all the GICC tables for same interrupt number, and ensuring
    a homogeneous ACPI based machine, could be used for other platform devices
    as well. Hence this refactors arm_spe_acpi_register_device() into a common
    helper arm_acpi_register_pmu_device().
