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 613/660] net: phylink: don't start and stop SGMII PHYs in SFP
- modules twice
-
-SFP modules connected using the SGMII interface have their own PHYs which
-are handled by the struct phylink's phydev field. On the other hand, for
-the modules connected using 1000Base-X interface that field is not set.
-
-Since commit ce0aa27ff3f6 ("sfp: add sfp-bus to bridge between network
-devices and sfp cages") phylink_start() ends up setting the phydev field
-using the sfp-bus infrastructure, which eventually calls phy_start() on it,
-and then calling phy_start() again on the same phydev from phylink_start()
-itself. Similar call sequence holds for phylink_stop(), only in the reverse
-order. This results in WARNs during network interface bringup and shutdown
-when a copper SFP module is connected, as phy_start() and phy_stop() are
-called twice in a row for the same phy_device:

-SFP modules with the 1000Base-X interface are not affected.
-
-Place explicit calls to phy_start() and phy_stop() before enabling or after
-disabling an attached SFP module, where phydev is not yet set (or is
-already unset), so they will be made only from the inside of sfp-bus, if
-needed.
