IBM Z / LinuxONE is supported by Red Hat and Ubuntu, which means we should eventually support the s390x architecture.

Linux s390 targets with official Ubuntu binutils etc. support:

stmmac: intel: Fix mdio bus registration issue for TGL-H/ADL-S
fa706dc 
On Intel platforms which consist of two Ethernet Controllers such as
TGL-H and ADL-S, a unique MDIO bus id is required for MDIO bus to be
successful registered:

Bluetooth: Add quirk to disable extended scanning
c1dacaf 
Broadcom 4377 controllers found in Apple x86 Macs with the T2 chip
claim to support extended scanning when querying supported states,

, but then fail to actually implement the extended scanning:
