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 639/660] net: phylink: fix link mode modification in PHY mode
-
-Modifying the link settings via phylink_ethtool_ksettings_set() and
-phylink_ethtool_set_pauseparam() didn't always work as intended for
-PHY based setups, as calling phylink_mac_config() would result in the
-unresolved configuration being committed to the MAC, rather than the
-configuration with the speed and duplex setting.
-
-This would work fine if the update caused the link to renegotiate,
-but if no settings have changed, phylib won't trigger a renegotiation
-cycle, and the MAC will be left incorrectly configured.
-
-Avoid calling phylink_mac_config() unless we are using an inband mode
-in phylink_ethtool_ksettings_set(), and use phy_set_asym_pause() as
-introduced in 4.20 to set the PHY settings in
-phylink_ethtool_set_pauseparam().
