Since patches 1-4 are all arm64, don't do any harm on their own and
conflict significantly with other arm64 changes queued for 5.14, I've
queued them in the arm64 tree on the stable for-next/cpufeature branch:

[01/20] arm64: cpuinfo: Split AArch32 registers out into a separate struct
https://git.kernel.org/arm64/c/930a58b4093e
[02/20] arm64: Allow mismatched 32-bit EL0 support
https://git.kernel.org/arm64/c/2122a833316f
[03/20] KVM: arm64: Kill 32-bit vCPUs on systems with mismatched EL0 support
https://git.kernel.org/arm64/c/2f6a49bbc01d
[04/20] arm64: Kill 32-bit applications scheduled on 64-bit-only CPUs
https://git.kernel.org/arm64/c/873c3e89777c
