 * pending-5.4/479-mtd-spi-nor-add-eon-en25qh64.patch

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"
