Some bigger changes were done to this feature and we did not port this patch yet:
 * hack-5.4/207-disable-modorder.patch

This depends on BOOTMEM which was removed from the kernel, this needs some bigger changes:
 * hack-5.4/930-crashlog.patch

A different version of the FPU disable patch was merged upstream, OpenWrt needs some adaptations.
 * pending-5.4/304-mips_disable_fpu.patch

- no crashlog support yet as a required file got deleted upstream
- Removed patch below, which is now seen as a recursive dependency [1]
- Removed patch below due to build error [2]
- fix still required to avoid identical function def [3]
- Fixes included from Blocktrron
- Fixes included from Chunkeey
- Fix included from nbd regarding "dst leak in Flow Offload"

-Subject: [PATCH 612/660] net: sfp: Stop SFP polling and interrupt handling
- during shutdown
-
-SFP device polling can cause problems during the shutdown process if the
-parent devices of the network controller have been shut down already.
-This problem was seen on the iMX6 platform with PCIe devices, where
-accessing the device after the bus is shut down causes a hang.
-
-Free any acquired GPIO interrupts and stop all delayed work in the SFP
-driver during the shutdown process, so that we ensure that no pending
-operations are still occurring after the SFP shutdown completes.
