Subject[PATCH 0/3] Preparations for Linux on Apple Silicon
Date
This patch series contains the changes to common Linux
kernel code that are required to boot Linux on Apple Silicon
Mac computers.

The changes:

- Support for FIQ interrupts in-kernel

This is required for the timer and IPIs on Apple SoCs.

- WFI hook

Apple processors do not keep register state across WFI.
As such, put a mechanism in cpu_ops to put a custom
sleep function instead.

- use nGnRnE instead of nGnRE on Apple processors

Device-nGnRE writes go to nowhere on Apple processors, as
such use MAIR to change those to Device-nGnRE writes.

Mohamed Mediouni (1):
arm64: mm: use nGnRnE instead of nGnRE on Apple processors

Stan Skowronek (2):
arm64/kernel: FIQ support
arm64: kernel: Add a WFI hook.
