Both these patches are already in the mainline kernel.
commit 1aa3d0274a4aac338ee45a3dfc3b17c944bcc2bc

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().
